English isn't everyones native language sometimes reading can help clarify things. Not everyone can hear either, watching miniquad clips doesn't require it but sometimes videos like these would be appreciated by even hearing impaired individuals
I read the headline and said to myself, the best prop is the one that suits the job. Then that's first thing you say in the description lol. I use HQ props, so good I don't even bother to balance them. I have 500 size quad so not a racer obviously. Great channel and your flying skills are amazing! Thanks
That view of things also translates to other stuff. I'm a computer scientist (and hobby electro engineer) and if people ask me what computer(parts) they should buy, I always say the same: Buy and use that what suits your needs. Not that what others want or say it's cool, not that what the ads say. Use that what you need!
Dear Steele, Please stop telling the community to throw their props in the recycling bin. I am a professional in the recycling industry and the company I work for designs and builds sorting equipment for large recyclers such as Waste Management, Republic Services or Recommunity. Any prop for mini-quads that is currently being made will, when thrown in the recycling bin, contaminate another product and ultimately end up in the trash. I can explain this to you in more detail if you are interested, but not in a YT comment section. If you want to truly recycle your props, you have to bypass the recycling bin, collect a lot of them (by polymer grade) and then find a processor who actually grinds and extrudes recycled plastic. With all my industry knowledge I would actually have a hard time finding a place like that since the polymers used for props are very specific. Sorry for the reality check, but I am not going to stop protesting - it is in the interest of my customers. Thank you for understanding in advance.
I’ve been surprised by the number of things I’ve heard shouldn’t be recycled. Like mixed paper + bubble wrap padded envelopes, pizza boxes (grease, apparently?), and apparently plastic grocery bags require special handling as well. It’s hard to know what’s legit or not, so I appreciate this info.
A_NU_ I have a new name! Woo! Thanks for the shoutout man :) I agree with a lot of what you are getting on about, it's a basic physics equation, the tricky part is the number of variable involved. I am still only seeing 80-90A in punchouts with the 5051 propeller. This is due to a few things, the F60-2450kv is still only running N45 magnets, which while less powerful also limit the amount of amps you can pull through the copper winding. The key aspect I enjoy with the 5051 (other than me and my cousin designing them, for racing, not for freestyle, we have some more designs in the works for that) is they are designed to work well with airflows. They are designed using custom algorithms that employ 3D flow studies and models, developed with a target for max efficiency in ENERGY TRANSFER, meaning more energy in more thrust out. Also due to the design they disturb the surrounding air a bit less, which helps with prop wash and high speed control. They are definitely a heavy prop, and I wish they were lighter myself, so we are moving into new design iterations with a focus on Freestyle rather than racing. Our end goal is to always engineer something for a specific goal, not for a generalist, we designs these props for a target speed of 60mph at 16krpm with a 45deg angle of attack. Anywho, let me know if you ever want to talk/hang/chill/design some new stuff, it's what me and my cousin love to do, that an fly all the time! Being in the air is #1!! Cheers Man!
I'm at the park now getting as many flights as I can here in Northeast Ohio. How many others like myself feel good about your progress over the summer! 😊 I stuck to acro all summer and finally feel great. Flips, Rolls, and power loops. Awesome feeling. Don't get much time to hit the park. Mostly front yard Los flying. Mr. Steel and others have inspired me to get good before winter. Damn it feels good. 6s chameleon with tons of kiss power. These esc are by far the most durable and best feeling. Learned a ton from you guys. Thanks so much
2 things. First, I feel like I just tried to get a drink of water from a fire hose! :-) Seriously though, this is super helpful but man, I'm going to save & rewatch a few times to get it all as I'm rather new to this. Thank you! Secondly, thanks so much for your stance on sustainability at the end. You get to test a bunch of stuff... so not "hawking" junk on your channel but only recommending what works over the long haul... is greatly GREATLY appreciated! Thank you!
Mr Steele totally agree with you. Some people just need to have fun with this and not worry about winning, that is what Banni and johnny is for! But for my set up I love the HQ 5040x3 gn with the 2205 2300kv, its just so locked in feeling but is still very responsive. But for me it feels like everyone is saying the best quad is the one with the most power but its really what YOU can do with what power you have.
I feel you in staying in the air. I don't get much time to fly anyways so when something breaks or just quits it's a real bummer. I enjoy building a quad but I can't stand having to take it back apart.
Steele, dude you hopped on frame and I almost said aloud, "Yo he looks so cool like that he died his hair silver! That's really cool looking." A million thumbs up on the new look Steele!!!
Like the new haircut. You are sporting the silver well. Thanks for the prop theory. I was asking about this today at my local hobby shop, this made it so much better. So... more theory please, they are not wasted videos! Cheers.
I just got those yellow HQ 5x4x3 props the other day and I love them. I feel I can control my quad more. Really helps since I'm still learning acro. No crashes yet with these props! Proud of my self. Lol.
Great video. I'll admit I was one of those you mentioned at the end trying to go big or go home......and go home to rebuild it or fix crap. Since then I have dialed it back a bit, increased the durability and reliance of things and its awfully nice coming home on the same props you left with.
Niice haircut. Thanks for talking through props and your reasoning for this and that. Should do more videos like this; talk more about what and why and compare/contrast. I like it. Thanks!
Nice haircut :) I personally like king kong 5*4*3 purple props, they are so hard to break and they are cheap. I break hq props like I break girls' hearts :p And I love when you don't miss the details like being translucent and transparent. Thanks for all your videos.
Thanks for the tips man. Not sure if you made a video on this but could you make one on mounting an action cam such as a Go Pro on a drone. Like how to make sure its balanced, weight distribution etc. I want to put a camera on mine but not sure how to do it. How would you keep it from pitching forward with the added weight on the front ?
Trap Warrior you move the battery further back to correct the cg of the quad. Generally for a H or X type quad, you balance them at the middle from the front to rear motors.
Great info! like the ending keeping it real, been vloggin and never realized the amount of tries it takes to get it right! the tree said, "GET OFF ME" EPIC!
Thanks mr. Steele the video is so good I have to watch it twice to catch everything that you're saying. There's a lot of good knowledge here about drones and weight and dependability. So thank you very much
A fine mantra, "If you're not up in the air you're not learning... or having fun." Rightious! Keep up the fine work my friend. oh! and Sub'd!!! Gotta look up races and meets here in Germany. This shit rules!!
Really god episode Steele. I've been flying nothing but HQ 5040x3 and 4x4x3 for the last year and a half as well. I see no reason to change. That said, I saw some crazy deals on the 4 bladed HQs for Black Friday so I picked a bunch up (also some 4 inch) to try them out. If I don't like them they will at least look great for photography (I shoot all my quads when I initially build them).
great video man. very good wisdom for newer people getting into the hobby. so many people screw up and end up constantly working on their quads and want these ridiculous prop / motor combos that just don't work well.
Love these videos.. Please keep doing them. I just recently bought a Kingkong 210gt and I'm still trying to find the right prop for me.. Thanks for all the Knowledge
Good vid Steel, like all of them. I want to add note on motor KV and copper fill vs power in regards to one of your comment of higher KV having less copper. Big picture: Changing the KV of a motor does not usually take away copper (unless you lower copper fill in the stator slots), nor does it alter it's torque output capability. Details: Changing KV means altering the dimensions of the motor or the number of turns per tooth. A 1000KV motor and a 2000KV motor are both capable of the same torque output and RPM, but the way you get there is a bit different. Assuming copper fill of each slot is the same but the turn count is different, i.e. say a 1000KV = 10 turns and 2000KV = 5 turns. The 2000KV motor will take 2x the current of the 1000KV motor to reach the same torque output and the 1000KV motor will need 2x the voltage to reach the same RPM as the 2000KV motor (but half the amps), so at some point it will make more sense from a controller standpoint to up drive voltage vs upping current. Ultimately total power (watts = voltage x current) output comes down the copper fill. Part of reason you can often get more power (watts) from the same prop running a higher KV motor of the same size is efficiency will drop. An electric motor makes it's peak power at 50% of motor stall torque, which is roughly 50% of the unloaded KV. Torque is proportional to input current (at least until you start reaching core saturation or have high eddy current losses which increase with RPM) I should probably make a vid on motor physics in layman's terms since this is a complex topic and I often see bad info. Nerd mode disengaged...crap, it won't disengage!
Yup, lots of bad info mainly due to poor anecdotes, but it is a complex subject. I design high current 3 phase motor drives/inverters and code FOC motor control for fun (and hopefully profit). Helps to know the physics + math. Too bad learning the sticks isn't as easy as learning theory :(
+ZombieSS77 thanks for the info. I understand there are not black and white figures when it comes to three phase motors however. For this lesson in general what I said is a basic understanding of how these things work. The more winds the lower the KV the less winds the higher. Obviously copper fill/gauge/stator design/and even magnet strength taken part in final KV numbers. But. You think beginners want to have their minds twisted into a pretzel talking about that stuff. I appreciate the info. But I did go to school for this stuff and I choose my battles My audience is not wanting in depth theory. If they wanted that there are other more technical channels out there. I provide basics and real world application not numbers and calculates that don't pertain to the average joe :) Cheers man The audience is the key. You don't tell the world you're burning x amount of C02 emissions a minute you tell them baby seals are dying.
I thinks Steele has good point in the video. Of course it is not the most accurate way of explaining things but it is easy to understand and it fits well to the audience, as Steele already said. The shaft power of a motor is torque times rotational speed, so if you double the KV of the motor and keep the torque constant, the output power also doubles. That's why speed, torque and power are all connected to each other.
The mildly autistic engineer that lives in my head escaped again last night; then he got stoned. I locked him up in his lab again and gave him some calculus equations to solve. I think the dude models himself after James May, but I'm more of a Jeremy "More POWER!" Clarkson fan. Wife and I love the vids, she's learning how to fly a mini quad as well (I'm so lucky).
Ha ha ha i freaking love u Steele! Funny stuff and good information in one video, love watching your flying and i try to learn stuff of it, but videos like this really helps me understand stuff a little better in theory so thank u! :)
Thanks for the opinions/facts/insights. I'd love to try all those props/batteries/etc. but I don't have the time or the money do to it (like you said, I want to fly... ) so I appreciate what you have to say about it. When I can't fly due to weather, the need to build something new/hot/hype is strong, but it's nice to have a voice of reason too. You are that voice Mr S.
Efficiency on mini quads only means gaining a few extra seconds of flight. What you give up for that doesn't make sense (subjective). Having extra power when you need it is a lot more helpful, being light on the throttle, instead of rapidly changing your motor speed (accelerating and decelerating) unnecessarily does a way better job. Mini quads are like f1 cars (people hear this all the time but it's the best parallel) at the end of the day they have one purpose to have fun, fly fast, and turn on a dime. And they do that well enough, start trying to maximize efficiency and you're going to lose out on a lot. I'll probably get a lot of slack for this but in all honesty the returns of efficiency are limited when it comes to this stuff. Pick the gear that lets you fly your quad the way you want. I see it all the time on forums about people arguing about the theory behind stator diameter vs height. It is cool stuff but people need to understand that what happens on paper doesn't always play out the same way in real life go out, have fun, and share the hobby with as many people as you can.
I absolutely agree with you. The quest for more kv and spinning giant airfoils and massive pitch with heavy props is pissing off batteries, and heating up ESC's and motors all for the sake of what, 60 seconds of fast forward flight? :-) For the freestyle pilots, the HQ 5x4x3 can't be beat. I, like you, use them on my freestyle setups. I sometimes will run a DAL 5x4x3, but they are thin and flexible, and you don't always get that locked in "snap" corner feeling. I have tested the new DJI snail propulsion system though with the 5048S Quick release props, and, just like you said, they utilize a bigger stator and lower kv to swing that prop efficiently. it's a 2305 @2400kv, and it's not a battery killer like I thought it would be. Great video as always man, and I think it helps get the info out there that basically a prop should fit your style and what you do, there isn't a cookie cutter, one size fits all approach to prop choice. One last side note, the bendable props, like the DAL and the PC, the "hit, bend and land" has caused me some grief in the past, nothing like bending a prop and having it bend downward only to wreck an ESC... oh what fun that is! Keep up the good work man, I talked to Chad, and the next time you are all in Ohio, I will be flying with you! (hopefully)
Hey, you consider the mass to quantify the ease to spin up and down, but in fact you should consider also the distribution of it which will actually make the moment of inertia. For spinning up, the shape of the prop will also matter as a strong angle and surface close to the center will be easier to manage than if it's far. I have no clue of how the racekraft fly, but their design is interesting and implies things going beyond the simple mass of the prop.
Lots of discussion about mass and only one comment about inertia. The moment of inertia is a more critical metric than simple mass. I blame public schools. Thanks Manuel!
Awesome videos man cant wait to get flying never actually had a quad copter that was decent but im inspired by all your videos man Ive seen the very first one all the way to this videos and I watched your style get smoother and sicker every video, I hope one day I can fly a pack with you see you around man.
Good video. Keep these types of vids coming! A lot can be learned from hearing different people's rationale as to how and why they chose a particular set up.
about time someone said all this stuff. next up is telling people that C ratings are bull crap on most lipos. uk company is trying to sell a lipo at something like 90 to 180 C. no way! keep them coming dude. super informative.
I dig that alot Steele. Consistency is important. I did all that keeping up with the Jones's and following the new hype this week shit. Spent alot of money and hours rebuilding quads because I thought this product was this and that product was that. Now I do what works for me. Sure I still try new products. I just dont go out and buy them for every setup and rebuild the whole fleet with the newest and hotest this week. LOL.. Thanks again man.
You know what would be useful... some text on screen with the model of prop while you are talking about each prop.
Xaviera Yayaell dammnn. people complain about everythinggggggg..!
English isn't everyones native language sometimes reading can help clarify things. Not everyone can hear either, watching miniquad clips doesn't require it but sometimes videos like these would be appreciated by even hearing impaired individuals
click on the cc icon on the video for subtitles
He would....but he lost the telemetry data
the consistency in his gear is why he is so good
I read the headline and said to myself, the best prop is the one that suits the job. Then that's first thing you say in the description lol. I use HQ props, so good I don't even bother to balance them. I have 500 size quad so not a racer obviously. Great channel and your flying skills are amazing! Thanks
+Pat B hash thanks man Glad to have you as a viewer. It's nice to hear from people with similar prop views
That view of things also translates to other stuff. I'm a computer scientist (and hobby electro engineer) and if people ask me what computer(parts) they should buy, I always say the same: Buy and use that what suits your needs. Not that what others want or say it's cool, not that what the ads say. Use that what you need!
Dear Steele,
Please stop telling the community to throw their props in the recycling bin. I am a professional in the recycling industry and the company I work for designs and builds sorting equipment for large recyclers such as Waste Management, Republic Services or Recommunity. Any prop for mini-quads that is currently being made will, when thrown in the recycling bin, contaminate another product and ultimately end up in the trash. I can explain this to you in more detail if you are interested, but not in a YT comment section.
If you want to truly recycle your props, you have to bypass the recycling bin, collect a lot of them (by polymer grade) and then find a processor who actually grinds and extrudes recycled plastic. With all my industry knowledge I would actually have a hard time finding a place like that since the polymers used for props are very specific.
Sorry for the reality check, but I am not going to stop protesting - it is in the interest of my customers. Thank you for understanding in advance.
Definitely. That contamination greatly reduces what gets recycled.
Thanks So much
Good info from mr Steele and from you airwolf FPV!
I’ve been surprised by the number of things I’ve heard shouldn’t be recycled. Like mixed paper + bubble wrap padded envelopes, pizza boxes (grease, apparently?), and apparently plastic grocery bags require special handling as well.
It’s hard to know what’s legit or not, so I appreciate this info.
A_NU_ I have a new name! Woo! Thanks for the shoutout man :)
I agree with a lot of what you are getting on about, it's a basic physics equation, the tricky part is the number of variable involved. I am still only seeing 80-90A in punchouts with the 5051 propeller. This is due to a few things, the F60-2450kv is still only running N45 magnets, which while less powerful also limit the amount of amps you can pull through the copper winding. The key aspect I enjoy with the 5051 (other than me and my cousin designing them, for racing, not for freestyle, we have some more designs in the works for that) is they are designed to work well with airflows.

I'm at the park now getting as many flights as I can here in Northeast Ohio. How many others like myself feel good about your progress over the summer! 😊 I stuck to acro all summer and finally feel great. Flips, Rolls, and power loops. Awesome feeling. Don't get much time to hit the park. Mostly front yard Los flying. Mr. Steel and others have inspired me to get good before winter. Damn it feels good. 6s chameleon with tons of kiss power. These esc are by far the most durable and best feeling. Learned a ton from you guys. Thanks so much
this is exactly what I needed. almost a year old but that RUclips magic puts it right up there for me. once again thanks dude!
I give you mad props bro... ;-)
Y Naut FPV nice
Nice one
Bro you are the most accurate and acceptable RUclips I never watch !!! Thank you !!
I think that repairing my quad is as cool as flying it:)
And its half the fun. I love building!
Building/Tweaking/Repairing are more Fun, than one would think :)
Happy Flying.
2 things. First, I feel like I just tried to get a drink of water from a fire hose! :-) Seriously though, this is super helpful but man, I'm going to save & rewatch a few times to get it all as I'm rather new to this. Thank you! Secondly, thanks so much for your stance on sustainability at the end. You get to test a bunch of stuff... so not "hawking" junk on your channel but only recommending what works over the long haul... is greatly GREATLY appreciated! Thank you!
LOL everyone's trying to imitate johnny!
Mr Steele totally agree with you. Some people just need to have fun with this and not worry about winning, that is what Banni and johnny is for! But for my set up I love the HQ 5040x3 gn with the 2205 2300kv, its just so locked in feeling but is still very responsive. But for me it feels like everyone is saying the best quad is the one with the most power but its really what YOU can do with what power you have.
Platinum video, great reminder that motors in all walks of life are designed for the specific load imposed on them.
I hate when trees say "Get off me" lol, very informative thanks!
I feel you in staying in the air. I don't get much time to fly anyways so when something breaks or just quits it's a real bummer. I enjoy building a quad but I can't stand having to take it back apart.
Steele, dude you hopped on frame and I almost said aloud, "Yo he looks so cool like that he died his hair silver! That's really cool looking." A million thumbs up on the new look Steele!!!
Really appreciate you're cognizance of longevity, Steele. Very important factor, from my point of view.
Wow you really know your stuff, thanks for helping clear stuff up Steele!
right with you at the end. its about fly time. building is fun, but flying is more fun. btw, nice hair cut!
Like the way you explain Mr. Steele. Thanks a million for your time and video!
Your a beast brother. A true artist. Appreciate all your work. Thanks
You provide a bank of information that I really appreciate. Hope to watch you fly in person someday. Thanks
Very informative !!! Oh and HAPPY BELATED BIRTHDAY!!!!!
Thanks. So true about things breaking. Nice to have a durable quad.
Thanks for taking the time to do these reviews Steele. Very helpful!
Steel, you need to do a podcast so we can listen and drive to work :) it will be Yuge!
SweepwingsRC let's drone out is a good start killing a few hours
SweepwingsRC he actully has one now! Check out failsafe weekly podcast! :)
been loving your FPV drone videos, you're a great talker and i love your attitude
love the honesty in your videos, keep up the good work
Like the new haircut. You are sporting the silver well.
Thanks for the prop theory. I was asking about this today at my local hobby shop, this made it so much better. So... more theory please, they are not wasted videos! Cheers.
nice harcut, way better than the bun ;)
I like the color too! Neat how they colored it so perfectly faded.
I just got those yellow HQ 5x4x3 props the other day and I love them. I feel I can control my quad more. Really helps since I'm still learning acro. No crashes yet with these props! Proud of my self. Lol.

You look great with that new style!! Really like it
Thanks for the pro tips. Keep up the good work Steele.
Excellent video with lots of great information! These are the types of videos I love to watch and learn the most from! Thanks for sharing!
AWSEOME Hair cut dude, good job cutting off the man bun!!! Keep up the good work, you are amazing!!
Niice haircut. Thanks for talking through props and your reasoning for this and that. Should do more videos like this; talk more about what and why and compare/contrast. I like it. Thanks!
I bet for 98% of pilots the last 30 seconds is the most relevant. You need a setup that keeps you flying and out of the shop. Great advice.
I really appreciate that you drop knowledge along with amazing flight videos. My adventure in the fpv world will happen this Xmas.
Nice haircut :) I personally like king kong 5*4*3 purple props, they are so hard to break and they are cheap. I break hq props like I break girls' hearts :p And I love when you don't miss the details like being translucent and transparent. Thanks for all your videos.

Just went back to two blade props after all these years. I like how they feel greasy in the turns. Analog 4 life
Glad to see the channel growing. Recent 'non-drone-centric' vids are great. Hope you keep it up.
Instructive as always ! Like the haircut.
Once again a good video, Thanks so much for taking the time to post this stuff. Peace.
Thanks mr. Steele the video is so good I have to watch it twice to catch everything that you're saying. There's a lot of good knowledge here about drones and weight and dependability. So thank you very much
Awesome video man, your knowledge is exceptional
Nice and in depth! Always learning something from you ;) and the haircut looks good imo :)
Almost 50K now man..... Congrats in advanced!
Kudos Steele, Very well said and explained!
Now, this was very interesting!
Thanks Steele!
Great vid. I use HQ 5x4x4 on all my quads, they feel amazing on tight corners and handling. Love the wisdom bro!
Thanks Steele. Many good points in this vid.
Thank you for addressing the man-bun controversy. We need leaders like you to take a stand on these important issues
Another AWESOME video filled with good info thank you sir!!!
brand new look steele.. 2017 will be a great year, and of corse finding the right prop for better performance its most important
Great video Steele, very informative. Thanks for this insight into props and letting us know what you like/don't like.
Great info to share steele. I love the old school glass fiber HQ props except every time i looked at them funny they would break. :D
A fine mantra, "If you're not up in the air you're not learning... or having fun." Rightious! Keep up the fine work my friend. oh! and Sub'd!!! Gotta look up races and meets here in Germany. This shit rules!!

Good to see other people with an understanding of brushless motors. The Torque/KV nonsense is really widespread.

I thinks Steele has good point in the video. Of course it is not the most accurate way of explaining things but it is easy to understand and it fits well to the audience, as Steele already said.
The shaft power of a motor is torque times rotational speed, so if you double the KV of the motor and keep the torque constant, the output power also doubles. That's why speed, torque and power are all connected to each other.
The mildly autistic engineer that lives in my head escaped again last night; then he got stoned. I locked him up in his lab again and gave him some calculus equations to solve. I think the dude models himself after James May, but I'm more of a Jeremy "More POWER!" Clarkson fan. Wife and I love the vids, she's learning how to fly a mini quad as well (I'm so lucky).
All you said, spot on Mr.
Yeah, I enjoyed your video! Will look at some others. Great job and helping my out. Thanks
Love your hair man, also like the beard with the moustache better than just the moustache.
You look older with this cut... I love it!
SemmyRace do you know how old is he?
Yankı Bora Ayman no, but compare it to other videos...
Great video steele i am currently using the same props you do an i love em.!
Awesome brother
Ha ha ha i freaking love u Steele! Funny stuff and good information in one video, love watching your flying and i try to learn stuff of it, but videos like this really helps me understand stuff a little better in theory so thank u! :)
Thanks for the opinions/facts/insights. I'd love to try all those props/batteries/etc. but I don't have the time or the money do to it (like you said, I want to fly... ) so I appreciate what you have to say about it. When I can't fly due to weather, the need to build something new/hot/hype is strong, but it's nice to have a voice of reason too. You are that voice Mr S.
Great video love HQ 5X4.3x3V1S PC! Have been gifted a set of HQ5x4x4r, following your video looking forward to flying them tomorrow...
HAHAHA love the outtakes at the end :) great info on how and why to choose props based on setup rather than "the in thing"
I agree 100%. That is it. More KV, more props angle, more more more... but less flight times, less efficiency, and less FUN!!!!!!
Efficiency on mini quads only means gaining a few extra seconds of flight. What you give up for that doesn't make sense (subjective). Having extra power when you need it is a lot more helpful, being light on the throttle, instead of rapidly changing your motor speed (accelerating and decelerating) unnecessarily does a way better job. Mini quads are like f1 cars (people hear this all the time but it's the best parallel) at the end of the day they have one purpose to have fun, fly fast, and turn on a dime. And they do that well enough, start trying to maximize efficiency and you're going to lose out on a lot. I'll probably get a lot of slack for this but in all honesty the returns of efficiency are limited when it comes to this stuff. Pick the gear that lets you fly your quad the way you want. I see it all the time on forums about people arguing about the theory behind stator diameter vs height. It is cool stuff but people need to understand that what happens on paper doesn't always play out the same way in real life go out, have fun, and share the hobby with as many people as you can.
So that's the deal with props!!
:-)
Thanks Steele
Seriously, thank you for dropping that knowledge. Much Respect!!
I've tried every prop under the sun. Always go back to HQ 5040x3. The RK 5040x3 or would be my second favorite
Fantastic info as always!
Damn fine work. The bad news is that even though you've "answered this question", people are still going to ask.
Great video man! Great stuff keep it up!
I absolutely agree with you. The quest for more kv and spinning giant airfoils and massive pitch with heavy props is pissing off batteries, and heating up ESC's and motors all for the sake of what, 60 seconds of fast forward flight? :-) For the freestyle pilots, the HQ 5x4x3 can't be beat. I, like you, use them on my freestyle setups. I sometimes will run a DAL 5x4x3, but they are thin and flexible, and you don't always get that locked in "snap" corner feeling. I have tested the new DJI snail propulsion system though with the 5048S Quick release props, and, just like you said, they utilize a bigger stator and lower kv to swing that prop efficiently. it's a 2305 @2400kv, and it's not a battery killer like I thought it would be. Great video as always man, and I think it helps get the info out there that basically a prop should fit your style and what you do, there isn't a cookie cutter, one size fits all approach to prop choice. One last side note, the bendable props, like the DAL and the PC, the "hit, bend and land" has caused me some grief in the past, nothing like bending a prop and having it bend downward only to wreck an ESC... oh what fun that is! Keep up the good work man, I talked to Chad, and the next time you are all in Ohio, I will be flying with you! (hopefully)
Hey, you consider the mass to quantify the ease to spin up and down, but in fact you should consider also the distribution of it which will actually make the moment of inertia. For spinning up, the shape of the prop will also matter as a strong angle and surface close to the center will be easier to manage than if it's far. I have no clue of how the racekraft fly, but their design is interesting and implies things going beyond the simple mass of the prop.
Lots of discussion about mass and only one comment about inertia.
The moment of inertia is a more critical metric than simple mass. I blame public schools.
Thanks Manuel!
nice breakdown, thanks!
I like "schubkraft" 3x4.5x5 props
Awesome videos man cant wait to get flying never actually had a quad copter that was decent but im inspired by all your videos man Ive seen the very first one all the way to this videos and I watched your style get smoother and sicker every video, I hope one day I can fly a pack with you see you around man.
Good video. Keep these types of vids coming! A lot can be learned from hearing different people's rationale as to how and why they chose a particular set up.
Awesome video Steele! I got to order some props now.
Lot's of very useful information, thank you! :)
Awesome video man! Thank you!
about time someone said all this stuff. next up is telling people that C ratings are bull crap on most lipos. uk company is trying to sell a lipo at something like 90 to 180 C. no way! keep them coming dude. super informative.
I dig that alot Steele. Consistency is important. I did all that keeping up with the Jones's and following the new hype this week shit. Spent alot of money and hours rebuilding quads because I thought this product was this and that product was that. Now I do what works for me. Sure I still try new products. I just dont go out and buy them for every setup and rebuild the whole fleet with the newest and hotest this week. LOL.. Thanks again man.
Good info. I have been using some of the almost indestructible DAL props since I crash way too much.
good video steele! like what you talk!
This was most helpful. That break down doh!
