@Del Halley if you've got something to say about him address the man himself... I mean he took the time to come comment in this youtube comments section, a real man of the people.
The future (like it or not) is sub250g and I've been saying that for quite a while already. Can't wait to see what you've come up with Tommy, as soon as I can afford to I'll buy into these motors, props and whatever frame you come up with. Sounds groundbreaking for all those who want to go sub250 without moving down to smaller frames. Great work man!
In Europe if its sub 250g but "has a sensor" it still needs to be registered... Ans you need a license. I don't see why anyone thinks the 250g limit will hold. They want you out of the air, it's not like they care about the size or safety, they just want you out.
@@cinialvespow1054 What is "a sensor"? An accelerometer is a sensor. A gyro is a sensor. You guys need to push back. Remember... governments are not your master, they are your servant -- they work for YOU. Don't be bullied!
@@xjet well said. I don't see what can be done though. Saying the government is your servant may be beautiful but it doesn't feel like that's actually true. I wonder if their classification of sensor / camera includes the fpv cam you use to see, as its not taking photos. How are we meant to make it better
@@cinialvespow1054 Their defintion of "sensor" includes any camera, even if it's not recording and just "streaming" (FPV). Even if you had no cam but a microphone, you'd need registration. The exact wording is: "a sensor able to capture personal data". Btw: You don't have to register the quad, but yourself as a pilot. You then get an ID and have to put that on any of your quads that require registration.
Enjoyed this a lot, but my only question is: Why develop in a bubble? It seems like you are ignoring all the other options in the last 5-6 months that use this same formula. Its cool to see the entire process, but especially frame wise, there are 3-4 options that i have reviewed that could have saved you some time. Noteably the DaveC mini long range 5" and the CMW Shocker lite. Cant wait to see the end result, and how it compares to the existing options. And it is also cool to see all the considerations that go into developing these solutions.
wth, this was THE BEST vid I have seen the last moths. In my country (The Netherlands) the EU laws are getting in place, they do make things easier but the 250 gram is really a turningpiont in what you are alowed to do and what not. I was really getting into fpv 2 years ago, spent a year on learing everything and for what to lookout for in fpv, bought 1 year ago the tinyhawk s, spent a year flighing that., its an awesome tinywhoop. Now I have made up my mind, I want to go into racing... So first, I need a spot to fly, very important! So I have 3 places where I could fly/race, but there is a chance that some people are going to hear and see it, so I need to keep the rules to play it safe and not risk fines. But back to the piont, max 250g is really a save weight to not get fined and still have all the fun that FPV quads bring. So I have been looking for parts to build a fpv racing quad for the last year, still getting more info on what to look out for. So I have a racing setup now, only need to buy the parts and looking for the right props... But now I think, I dont gonna spent 300 on a quad and have to buy 6 lipo's for getting the risk getting in trouble... So max 250 is I think now from now on my new focus piont to study on.... (still dont have a 5 inch quad) But I love to see more of these kind of vids to study on what parts to buy and to look out for... Also I might start looking for study vids on the combination of props and motors, I dont have seen much vids on that subject, but it is a very important factor on how your quad will fly in the end. Anyway, thanks for the info and the awesome vid!
I just bought my first two packs of umma grip (1 tbs version and 1 lite) and watching this video makes me a lot more proud to use the umma grip. Respect.
The best part of this is making "Mag Motors" modelled after your favorite wheels. When your drone matches your car ...well, let's just say ... you are complete.
9:15 man tommy, what a throwback! my first quad was a ZMR250 on 3S with 5030 props, over 5 years ago now and I thought it was the greatest thing ever! It's amazing not only how far we have come, but that we've come full circle too!
@@ummagawdFPV i know right?! idk about you but it just blows my mind. Also, in a somewhat related note I think you might be somewhat on the wrong track with a sub250 freestyle build, you seem to not be taking around the mass of the quad relative to prop disk area into account. Part of the reason toothpicks fly like toothpicks is because of their relatively low mass relative to the area of the prop disks, you can see this by comparing how say.... a 2" vs a 3" toothpick at similar masses fly. I'm sure your 5" sub250 will fly great when it's done, but it makes me wonder: What would happen if we came up with a 3.5" prop based quad built around a target AUW of 248g? Either way, keep up the good work Tommy!
I have been known to do, what you call, over propping with excellent results (ok, I don't fly stunts). I have had two sub-250 gram 5-inch quads powered by BrotherHobby 1504.5 3950 KV motors. Smooth flight, stable, and no wobbles. Of course, my throttle is normally about 30 percent when flying these rigs; just nice cruising around at high altitudes.
I love my Flywoo Explorer LR, its got great flight times, some light freestyle chops and a decent top speed of 60mph. Batteries on this quad are everything since performance is relaxed so I only fly 4s 850 Rline packs on it since the voltage sag is minimal and you get recovery very soon.
Thank you, that was really entertaining to watch ! That said if you want a balancer freestyle quad under 250g AUW, go for 4 inch... I built a Micro Reverb with 1408, 20x20 stack, Gemfan 4023, 850mAh 4S Tattu and it flies really well ! 5-6min freestyle, up to 10min cruising...
Awesome content Tommy... I may be against you on this one but I like the 4" for the ± 250g setup. Has enough prop area "float" to still "feel" heavier more like a traditional 5".
4" these days (with the right setup) is definitely good (I was using a Dave C micro LR frame and 1505s). It's what had me thinking what could be done with 5". We'll see!
This format is so smart it shows the perceived value of what you’ve put into this, the thought process you’ve used and I like that you have brought us along for the ride this is the way to claim the innovations that you’re doing before they get cloned. I like what you’re doing and I like how you’re doing it.👍🚀
Thanks for taking notice. I've learned that I can't fight the "cloners", and that I'll never be able to compete with their "race to the bottom pricing". So I decided I'd just be open about my story/journey and if you're down, then great. I hope you'll support it in however way you find fit. It became easier for me to find my path when I realized that I do this for people like yourself, not the people waiting for the clone version. 🙏🤙
The interesting thing is that you only need a beefy frame because you're carrying quite a bit of weight into a crash. When you reduce the auw, you don't lose much durability per gram you reduce it by (again, law of diminishing returns here) because there's much less mass going into the crash
This is actually what i've been missing for a lot of the build videos... Which architectural decisions went into the "picking between options" part of the design. Love this video !! Because It's not like if you produce something REALLY good like the Flywoo Explorer LR that others won't try to reproduce it using their parts... (and sometimes fail like on the diatone Roma)
Glad you found it useful. I feel like this part of the story really helps people understand the intent/purpose of the build and so they can make better decisions towards their own builds. That said, I def anticipate the Flywoo's of the world to reproduce it. Which I'm OK with. I don't do this for them, I do it for people like yourself.
PROPS!!! Thanks for sharing... Great mix of micro motor elements into the design... Love the idea of designing a motor and custom prop for this. thats one way to solve a possible regulatory problem.. and be closer to what we all know and love with standard 5 inch quads.
I like KababFPV's analytics and his motivation but you take it to another level. Maybe your not as scientific but certainly much more fun and enjoyable to watch! Just love it! Keep it up!
Just to add,just finished my last Build sort of using stuff I had left over, F7 AIO, GS 35amp esc, Emax 2206 last of my analog transmitter and cameras, I’m right in the MIDDLE of the analog - hd switch, having the Dom V3s it’s got hdmi in so the Sharkbyte is a good not to expensive move, So I’m just hedging my bets at the moment!! You can see my predicament, FATSHARK ole!, £500.00 + module,! Or sell and Dji??
I use a similar sub-250 gram build methodology, however, I break down a little differently. First, take 1/3 (83 grams) off as a battery allowance which leaves 166 grams for the dry weight of the quad. Divide this by 3 which is 55.3 grams for each of the 3 subsystems of the quad. 1) Electronics (everything electrical except the motors), 2) Frame (including standoffs, bolts, TPU parts, etc.), 3) Propulsion (motors, props, bolts, etc.). For any given type, the electronics are pretty much the same. I use the same FC, Camera, VTX, Receiver, etc. in all of my builds (ok, there may be a couple of grams difference, but still close) The 2 subsystems that sort of balance between each other are the Frame and Propulsion; IE: lighter frame means more for motors. The reality is that 15 grams is about the maximum weight for a single propulsion unit (motor, props, bolts) regardless of the physical size. Generally, T-Mount motors weight less than 5mm prop mount motors. >> First, put together the lightest electronics package (yeah, analog). Next, use the lightest frame that you can find; look for less than 50 grams. If you get these two down, that will give about 10+ grams to add to the propulsion system which might allow for 18 grams per unit. Keep in mind that the battery weight can not exceed 83 grams unless you want to compromise somewhere else.
You're on the right track! I would highly recommend also trying Gemfan 5125 triblades. If you want a solid frame to do testing on until you're own design is ready look into the ET5 from Racer X. 4s 850 seems to be about the optimal size and weight compromise on batteries. Alternatively, if you go with higher motor kv (3000-3500) running a 3s 1100 mah pack can work really well. A 1000 uf capacitor attached directly to the battery pads can really help smooth out motor response on these light weight 5" builds. I'm currently really enjoying a build with 2203 3450 kv motors. It flies really well with a 4s 850 and Gemfan 4023 triblades, or 3s 1100 and Gemfan 5125 props. The auw ends up right about 265g either way. Switching to your new motors would probably be enough to get me under that magic 250 number. I'll be looking forward to seeing how this project turns out.
Here is one way you can lighten the quad, use the Sony VTC6 battery it is small low weight and is a 3000mA hr that can run to very low voltages. Normally used in those Vape cigarettes and you can always hook up two , three or 4.
Yep for light weight 5 inch 2004 is a good spot. It's going to be interesting to see your take on the frame versus other people who have made frames for the same idea.
I really like your style, your personality and what you are doing. A cool guy, with great knowledge, presenting great things. You have something other's youtubers don't have in the fpv landscape. Your language seams "free of interest" to me, even if you are taking about motors you will sell at some point. Keep this mindset. Thanks 👍
Thank you Julien. Yea I don’t like shoving things down people’s throats. I’m just sharing what I’m trying to do, and if you’re interested in the same things and agree with my findings... then cool. And if not, then hopefully I made ya laugh
I think the axis on the graph should have been reversed there (without changing the graph itself. What happens there is that the motors are infinitely responsive and stable as the graph continues to the right instead of hitting a limit. Sick motors there, can't wait to see the frame!
I really like this video and style. I know it took longer to make, but it’s just as good (or better) than anything on TV. I teach, and I want students to watch this it’s so good. Thanks for making it - and including all of us on the journey.
If you can pull this off, you would have found the "Holy Grail" of FPV. According to Kabab, that 250g number dates back to some random number that was pretty much pulled out of the air.
It might be that frames have to stop being flat panels water jetted out and the arms have to be angle or C chanel so they can be thinner, lighter yet strong.
The 2003 motors are plenty on 3s for 5” and super efficient. Already been flying the 5” t mount and that’s where it’s at. CANT run 4s on 3450kv without a ton of problems on a whoop fc. Of corse the kv can be lowered to make it work. But the sweet spot for light weight is definitely 2003’s and they have a ton of thrust. Specifically the stanfpv/bob rougy 2003’s Get some you will see what I’m saying. Bob has recently upped his motor to a 2004 for more throttle precision for a more rounded motor that can do heavy quads also, but if you want to do a lighter setup the 2003’s are insane!
250g is a game of compromises and I personally think 5" is out of the sweet spot for 250g. If you optimize everything for 5" the best outcome you can expect is a quad that flies nicely for 3 minutes but hasn't the best grip and is fragile. 4" on the other hand makes it much easier to build an agile quad with 3 blade props and a more robust frame. Both ways even a GoPro Session will be bad for performance so it's either 1080p from the air unit or analog with a Tarsier or Hybrid. I'm really excited about 2004 motors ever since I listend to KabapFPV's endless ramblings about stator dimensions. They do look sexy. I hope there will be a version with something around 2100kv for 6S (4").
Lol. Those phone calls actually went down exactly like that. “We need the frame for the 2004 motors... never mind we can test with the moongoat... just kidding, we need a frame to test these motors...”
Those interested design should pick up a free user Fusion 360 account. Once a person gets comfortable making a model they can start to save all those models into a folder. These models can then be treated as a component. Creating a library of parts(everything from FC/ESC stacks to Cameras even down to the props) takes a lot of time. But then when it comes for a new design it GREATLY reduces the time to make a new frame design. I had one build where my 3.5in Advan props were modeled to come within less than 1/16 inch of the camera mount/frame. After being built the clearances were to spec and parts fit, for that motor/prop combo. Fusion 360 can give you a volume for parts you design which you can then use with known density of materials and you can come really close to weight estimates for the parts you use. Inserting a model as a component and then having a 3D print, the milled parts, and the electronics all fit just like the model shows is one of the more satisfying feelings I have had in the hobby. Have done 3in ducted builds all the way up to Kaiju sized 22 inch monsters. It took me a good 6-8 months before I started to use components properly. But now it has become fairly enjoyable when I decide to sit down and design something. Put in a movie, or 4... and do a 10-12 hour design session. Have had 3D printer going along with CNC all at the same time. Feels like a Tony Stark kinda moment. CAM side of Fusion 360 and learning tool paths and feeds&speeds is a whole another ball of wax.
I tried making a crazy-lite 5 inch with those HQ 5030 t-mounts (great props!) but with only 1404 motors. Was super fluffy and floaty, and very unsatisfying. When I can afford it, I think the 2004's will hit the sweet spot.
Finally a FPV video with a story behind it. Videos lately have been getting a bit same old same old. Even my cat sat and watched it with me (she loves fpv too) You had me gripped for the whole video and really looking forward to Part 2. Hats off to you Amazing peace of work. 🤘🏻Peace
Nice job! I was waiting for soft mounting the motors. Looking forward to more insight on the motors. May be looking for some lighter ones soon for 6s to give me a bit longer flight time. I just tend to cruise.
Dang dude. I am working on the same thing, dealing with the same issues, the video format is right on, but... I am sitting here on the edge of my seat waiting the the holy grail and the episode ends.
I loved this video and those motors, what would you recommend for a 4 inch long range build using the flywoo Explorer lr 4 v2 frame, 3000mah 4s1p and 3000mah 6s1p lithium ion batteries
Great! Go for it! Here are several questions for Part 2 ESC: you will probably get away with a "small" ESC. Do you know how many Amps you are targeting? I'm thinking about the SucceX-A 40a F4 AIO flight Controller special for DJI with 30.5*30.5mm mounting. For the frame: please think not only about traditional small stacks or "whoop" style mounting but also 30x30. Great job!
I get into it more on the next video but the answer is YES. Thankfully, this motor/prop combo doesn't pull much amps. And... noted on the AIO suggestions (I think you'll be happy with what we came up with)
I can appreciate the work you are doing but I think the FAA is going to require Registration for all drones if everyone tries to skirt around the current regulations. I don't mind Registration or maybe making sure people have AMA membership because that comes with some insurance coverage. I don't like being over regulated but being an American we should be used to it.
this was the greatest ummagawd video i have ever seen and i want those motors
That it’s cause u came late to the party ... and u where looking nurk channel for shure
Great vid! Totally agree, love the weight of 5 inch freestyle.. a scaled down fs rig would be ideal 🤩..

When will you finish your quad i mean this build i desperately waiting to see
I love the cinematic video and the comedy that you added. I can’t wait to see the complete build on your site

Just to add,just finished my last Build sort of using stuff I had left over, F7 AIO, GS 35amp esc, Emax 2206 last of my analog transmitter and cameras, I’m right in the MIDDLE of the analog - hd switch, having the Dom V3s it’s got hdmi in so the Sharkbyte is a good not to expensive move,
So I’m just hedging my bets at the moment!! You can see my predicament, FATSHARK ole!, £500.00 + module,! Or sell and Dji??
I use a similar sub-250 gram build methodology, however, I break down a little differently. First, take 1/3 (83 grams) off as a battery allowance which leaves 166 grams for the dry weight of the quad. Divide this by 3 which is 55.3 grams for each of the 3 subsystems of the quad. 1) Electronics (everything electrical except the motors), 2) Frame (including standoffs, bolts, TPU parts, etc.), 3) Propulsion (motors, props, bolts, etc.). For any given type, the electronics are pretty much the same. I use the same FC, Camera, VTX, Receiver, etc. in all of my builds (ok, there may be a couple of grams difference, but still close) The 2 subsystems that sort of balance between each other are the Frame and Propulsion; IE: lighter frame means more for motors. The reality is that 15 grams is about the maximum weight for a single propulsion unit (motor, props, bolts) regardless of the physical size. Generally, T-Mount motors weight less than 5mm prop mount motors. >> First, put together the lightest electronics package (yeah, analog). Next, use the lightest frame that you can find; look for less than 50 grams. If you get these two down, that will give about 10+ grams to add to the propulsion system which might allow for 18 grams per unit. Keep in mind that the battery weight can not exceed 83 grams unless you want to compromise somewhere else.
EPIC video, thanks Tommy. Looking forward to the next one.
this is possible the most exciting thing in 2020 and you have orange motors... im sold
You're on the right track! I would highly recommend also trying Gemfan 5125 triblades. If you want a solid frame to do testing on until you're own design is ready look into the ET5 from Racer X. 4s 850 seems to be about the optimal size and weight compromise on batteries. Alternatively, if you go with higher motor kv (3000-3500) running a 3s 1100 mah pack can work really well. A 1000 uf capacitor attached directly to the battery pads can really help smooth out motor response on these light weight 5" builds.
I'm currently really enjoying a build with 2203 3450 kv motors. It flies really well with a 4s 850 and Gemfan 4023 triblades, or 3s 1100 and Gemfan 5125 props. The auw ends up right about 265g either way. Switching to your new motors would probably be enough to get me under that magic 250 number. I'll be looking forward to seeing how this project turns out.
Really nice video editing! Enjoyed watching it. Would like to take a closer look at your quad wall! 😉
yea maybe I should do a history episode of my wall
@@ummagawdFPV That would be nice! Greets from Germany.
Here is one way you can lighten the quad, use the Sony VTC6 battery it is small low weight and is a 3000mA hr that can run to very low voltages. Normally used in those Vape cigarettes and you can always hook up two , three or 4.
Yep for light weight 5 inch 2004 is a good spot. It's going to be interesting to see your take on the frame versus other people who have made frames for the same idea.
I really like your style, your personality and what you are doing. A cool guy, with great knowledge, presenting great things. You have something other's youtubers don't have in the fpv landscape. Your language seams "free of interest" to me, even if you are taking about motors you will sell at some point. Keep this mindset. Thanks 👍
Thank you Julien. Yea I don’t like shoving things down people’s throats. I’m just sharing what I’m trying to do, and if you’re interested in the same things and agree with my findings... then cool. And if not, then hopefully I made ya laugh
@@ummagawdFPV Definitely a cool guy
BEST FPV VIDEO / STORY EVER !!! LOVE IT!!!
Thanks T. Looks good so far. Can't wait to see what comes of this.
Sub 250g is what I want. 😉👍
I think the axis on the graph should have been reversed there (without changing the graph itself. What happens there is that the motors are infinitely responsive and stable as the graph continues to the right instead of hitting a limit. Sick motors there, can't wait to see the frame!
I really like this video and style. I know it took longer to make, but it’s just as good (or better) than anything on TV. I teach, and I want students to watch this it’s so good. Thanks for making it - and including all of us on the journey.
So good! Your greatest video yet man! Looking forward to the next one!
thanks Wynn!
If you can pull this off, you would have found the "Holy Grail" of FPV. According to Kabab, that 250g number dates back to some random number that was pretty much pulled out of the air.
I just made a sub 250 racer using the betaFPV 2003 motors, goes hard
great video!!! would love to see more videos like this in the fpv world
Best video of them all. Technical, informational, funny. No offense to others but you're the best.
thanks man!
Work in progress, nice to follow along :)
Another good option to keep in mind. At this point, for light weight builds, the best quality hd camera option seems to be the insta360 go.
That was extremely well done Tommy. Loved it.
thank you. You answered my prayers. Definitely getting a set for my 360 build
I'm very curious and intrigued with one of these builds. I'll be staying tuned to see what you come up with for a frame. I'll am for sure on board.
This might be my favorite vide you have ever made. Can't wait for part 2. You the man UMG!
thanks 🤙🤙
It might be that frames have to stop being flat panels water jetted out and the arms have to be angle or C chanel so they can be thinner, lighter yet strong.
Once again Tommy at his Best !! Love your ideas man !!
The 2003 motors are plenty on 3s for 5” and super efficient.
Already been flying the 5” t mount and that’s where it’s at.
CANT run 4s on 3450kv without a ton of problems on a whoop fc.
Of corse the kv can be lowered to make it work. But the sweet spot for light weight is definitely 2003’s and they have a ton of thrust.
Specifically the stanfpv/bob rougy 2003’s
Get some you will see what I’m saying. Bob has recently upped his motor to a 2004 for more throttle precision for a more rounded motor that can do heavy quads also, but if you want to do a lighter setup the 2003’s are insane!
Hmmm... you should stay tuned for the next videos then... lol I think you might be surprised
Very interesting and exciting journey. Love your Acrobrat frame and Brat motors. Can't wait to see the rest of the story. 💖🤓
This style of video was excellent. Loved the storytelling
Following !,, in the UK! Similar rules but no remote ID!! Frame Next??
Yup!
Totally liked the story, looking forward to the next chapter.
Story telling. Nailed it. Can't wait for part 2. Keep on rocking man
thanks Jose
can't wait to see the final build!
250g is a game of compromises and I personally think 5" is out of the sweet spot for 250g. If you optimize everything for 5" the best outcome you can expect is a quad that flies nicely for 3 minutes but hasn't the best grip and is fragile. 4" on the other hand makes it much easier to build an agile quad with 3 blade props and a more robust frame. Both ways even a GoPro Session will be bad for performance so it's either 1080p from the air unit or analog with a Tarsier or Hybrid. I'm really excited about 2004 motors ever since I listend to KabapFPV's endless ramblings about stator dimensions. They do look sexy. I hope there will be a version with something around 2100kv for 6S (4").
Stick around then... what I found with this setup might change your mind.
@@ummagawdFPV Definitely will. Very excited about your research. You've proven that you will not settle for subpar configurations.
Lol. Those phone calls actually went down exactly like that. “We need the frame for the 2004 motors... never mind we can test with the moongoat... just kidding, we need a frame to test these motors...”
If you can fit a well protected naked gopro/smo 4k in a 250g 5 inch, I'd be very impressed. That's really all I need! Great video
Really fun! It had everything! A dramatic story, sick vibes, a slick dance number, and a Kabab-like chart! 👍
I try to sprinkle a little of everything when I get a chance
Bro! I love this! More please!
thanks man (I love your name btw)
Can't wait to see the resolution.
Freakin amazing!
Absolute genius Tommy!!!
Now that’s content that just raised the bar for everyone creating for the fpv community.
Well done 👍
such an amazing experience. sign me up for those motors man !!! can't wait for the second part
Those interested design should pick up a free user Fusion 360 account. Once a person gets comfortable making a model they can start to save all those models into a folder. These models can then be treated as a component.
Creating a library of parts(everything from FC/ESC stacks to Cameras even down to the props) takes a lot of time. But then when it comes for a new design it GREATLY reduces the time to make a new frame design.
I had one build where my 3.5in Advan props were modeled to come within less than 1/16 inch of the camera mount/frame. After being built the clearances were to spec and parts fit, for that motor/prop combo.
Fusion 360 can give you a volume for parts you design which you can then use with known density of materials and you can come really close to weight estimates for the parts you use.
Inserting a model as a component and then having a 3D print, the milled parts, and the electronics all fit just like the model shows is one of the more satisfying feelings I have had in the hobby. Have done 3in ducted builds all the way up to Kaiju sized 22 inch monsters.
It took me a good 6-8 months before I started to use components properly. But now it has become fairly enjoyable when I decide to sit down and design something.
Put in a movie, or 4... and do a 10-12 hour design session. Have had 3D printer going along with CNC all at the same time. Feels like a Tony Stark kinda moment.
CAM side of Fusion 360 and learning tool paths and feeds&speeds is a whole another ball of wax.
I tried making a crazy-lite 5 inch with those HQ 5030 t-mounts (great props!) but with only 1404 motors. Was super fluffy and floaty, and very unsatisfying. When I can afford it, I think the 2004's will hit the sweet spot.
that's that 'sad face' territory I'm talking 'bout 😉
Awesome! waiting for the next part.
Finally a FPV video with a story behind it. Videos lately have been getting a bit same old same old. Even my cat sat and watched it with me (she loves fpv too) You had me gripped for the whole video and really looking forward to Part 2. Hats off to you Amazing peace of work. 🤘🏻Peace
well thanks man! (and thanks to your cat too)
Nice job! I was waiting for soft mounting the motors. Looking forward to more insight on the motors. May be looking for some lighter ones soon for 6s to give me a bit longer flight time. I just tend to cruise.
Dang dude. I am working on the same thing, dealing with the same issues, the video format is right on, but... I am sitting here on the edge of my seat waiting the the holy grail and the episode ends.
we'll figure it out! 😉
I loved this video and those motors, what would you recommend for a 4 inch long range build using the flywoo Explorer lr 4 v2 frame, 3000mah 4s1p and 3000mah 6s1p lithium ion batteries
probably a 1404
Great! Go for it!
Here are several questions for Part 2
ESC: you will probably get away with a "small" ESC. Do you know how many Amps you are targeting?
I'm thinking about the SucceX-A 40a F4 AIO flight Controller special for DJI with 30.5*30.5mm mounting.
For the frame: please think not only about traditional small stacks or "whoop" style mounting but also 30x30.
Great job!
I get into it more on the next video but the answer is YES. Thankfully, this motor/prop combo doesn't pull much amps. And... noted on the AIO suggestions (I think you'll be happy with what we came up with)
Awesome man. I absolutely love them. When I do a lightweight build I'll be sure to grab a set of these babies!
Really enjoyed this style of video. Funny, informative and really cool to see a little behind the scenes of development. Can’t wait for the next part.
I can appreciate the work you are doing but I think the FAA is going to require Registration for all drones if everyone tries to skirt around the current regulations. I don't mind Registration or maybe making sure people have AMA membership because that comes with some insurance coverage. I don't like being over regulated but being an American we should be used to it.
