This is entertaining. Far as Landing goes I wound pull off the goggles and landed line of sight. Or enable auto level mode. Please keep this going I want to see more👍😀
Nice one Dave! Always creating. Thanks for sharing your imaginations… and a definite big thanks to your Flywoo Explorer LR design.. of all my 12 quadcopters it’s the one I’ve been flying with the most. 🙏🏼👍🏼🔥🔥🔥
I was asking about something like this in Kabab's Facebook group. Almost everybody said it couldn't be done, I was only thinking of 150 mph and at that time I didn't have a 3d printer, but now I do. Thanks Dave
WOWee that was fast my friend. Add some smoke and when take off, punch the throttle hahaha. it will be a rocket take off. Did you try the new Flight one firmware? that might give even more control over all parameters and PIDs.
Findest du GNB oder Tattu besser? Und hast du schonmal die SLS Noc Race ausprobiert? Ich hab mir davon gerade ein paar geholt und ich finde die schon ziemlich insane
Someone just showed me this. Pretty awesome. Not unlike Ryan L's rocket quads. Get that GPS inside and moving the motors forward a bit to balance the weight with the battery will help a little although aero is far more important than a bit of weight distribution at this point. Polish the walls if possible. From my discussion with Ryan, the center of pressure is extremely important. Also, detune the quad a bit to assure you're getting to max rpm. You can consider putting something over the FPV cam as well. With aero like that, you also don't need a triblade as much. An aggressive twin will get you significantly more speed. Impressive speed already, you could probably get it up around 290+kmph on whatever drivetrain that is on it already which would be pretty incredible for a 3". Great work as usual. Ryan was doing around 170mph on 4S with his 5" things. It looks like he's made his highest speed runs private but check out the videos he has up. Pretty interesting ideas. 200mph on 5S ruclips.net/video/CIsZSAUcGbw/видео.html Six gram 5" frame ruclips.net/video/y8v-NvAYVo8/видео.html His site downanddirtydrones.wpcomstaging.com/portfolio/xlr-1/
Thanks man! I didn't really mess around with those high speed builds lately because the whole Flywoo Explorer thing kept me busy but I have a new version of it in the making that is powered by 4 small EDF jets😅 Also included things like two cams with an aux switch and smoother surfaces 👌🏻
@@DaveCFPV awesome. Consider using the upcoming Ant Lite 4:3 that I had them make specifically for me and stick one directly in the nose and another at about 45 deg. The lens is such that you can mount it flush with the exterior really easily. They're making this version of the Ant Lite the default one in the 4:3 version
Magic! I think you would do well marketing your Rocket Drone and wish you well in doing so. Perhaps add a parachute - take it high switch off then open parachute maybe.
Hey Dave, excellent video. Have you thought about creating or modifying an existing design for a cinematic 4" drone which can carry the caddx vista? I think your project microlongrange is an excellent fit but 16x16 stacks are less common and less capable than the 20a whoop boards. What do you think? Seems like 4" would be a better balance vs 3" to carry the extra weight of the vista.
If you order the 4in Micro Long Range frame from Nick at CNC Madness, he has a version with holes for dual 20x20 stacks, pressed mounting nuts and chamfered arms.
Hey! Thanks! Actually the Microlongrange can carry the Vista already. Fits perfectly. I know 16x16 are less common but they are the only way to have a very compact frame. CNC madness however sells a few different Versions that are stretched by 6mm and have mounts to fit 20x20 stacks and AIOs
To make it faster, print with ABS, it's density is around 1.04g/cm3, compared to PLA 1.24 g/cm³. You can also get better aerodynamics with acetone smoothing
Would it be feasible to drop a cheap FPV cam inside the tail where the antennas come out, put on a diff vtx channel and switch to that for landing? Just thinking out loud..... Great video, I may need to build one.
@@SCFPV surprisingly one of the fastest rtf quads you can buy is a 3 inch (some diatone quad that can do 6s) it does 120mph, but 40mph is a lot aerodynamic wise I think
Quick question, I just printed out your design and I’m about to build it all out, but I was wondering, did you place the battery in the middle section or the bottom section? I’m in Italy currently, so the weather is still good to fly this quad for a little while longer.
you can use Colorfabb's lightweight PLA for non structural but aerodynamic parts. this material foams up in the nozzle depending on the temperature it's printed at and can foam up to 3 times its normal volume, allowing for 66% weight reductionof these parts. it's not quite as strong as regular PLA, but for aeroydnamic fairings and light hardware brackets it's a real weight saver. I used it on a 2,5m wingspan airplane for the nose cone, wing /fuselage intersection fairing and leading edges of the wing and tailsurfaces.
That is really something! You could catch that with a butterfly net to avoid damage. Or even stick it into the ground and fly the quad into it. Thanks!
You need the cam on a pivot controlled by a small servo and a switch. 90 deg out the side for t/o and landing, or pointed towards the nose for speed. Seems you could easily work out a pivot mount for the cam and a mount for the servo for v3 print.
Easier to have a 2nd camera and just switch from high tilt for speed run and to low tilt for landing. Less weight and more reliable. Bicks Multiview is what I use on my Cheaters and works great. Also ViFly or one of the dual cam FC would work.
Forgive me if this question has already been answered or if it a stupid question, but what is the position of the quad during flight? Is it flying like a normal quad, with propellers pointing up? From the video and the footage from the quad I would say the nose is pointing forward, which would put the motors and props turned 90 degrees facing into the wind. If That's the case, how were you achieving that constant during flight? Maybe next video you could have the sticks showing in your OSD. Very interested in how you piloted this quad
Yes exactly the Flight controller is programmed just like on a regular configuration with the motors on a horizontal plane. I fly it in Airmode which makes the Controller stop trying to Autolevel and instead hold the current angle. So I just need to tilt it by pushing the sticks foreward and back to neutral and it will stay pointing foreward untill I push them in the reverse direction
Two cameras at two different angles on two different channels. Flip channels to land. Landing cam can be low quality and at a really low transmit power level since it will be near you on landing.
If you put a distance sensor at the rear end and 3 legs like a space x rocket controlled by a servo by distance read, u will be able to use auto landing with help if the distance sensor. Its basicly a pid for height controll. But for landing you will need to use the sensor and not your altitude with a set value of 0.
Very cool. I have a 3D printer on the way. I plan to attempt some sort of quadcopter and airplane hybrid myself. Thanks for sharing your work with us. It was entertaining.
there is FC that support two camera inputs and can switch between them (also i believe, if i remember correctly dronemesh has a board that can do that even on a regular fc) so you could go with a dual camera setup - one for flying, one for landing
Nice, very nice. You could have the camera tilt using a servo and a spare channel on the link so at the flip of a switch it points the camera down to "landing mode" and then before you take off you set it back to "speed mode"
Do you have an idea of what the top speed of the hardware you used is on a standard frame. Curious how much of a difference the aerodynamic frame makes. Don't think that the extra frame weight will make much difference in the top end, but will in terms of responsiveness. The body seems quite wide, although I suspect that it's probably as small as you could go to be able to fit the battery. Any room to be able to reduce the cross section area? Could you make it thinner with a different battery configuration. Eg 2x3S packs stacked on top of each other. Your current design allows you to change camera angle, but comes at the expense of a large turbulence creating hole at the leading point. Be interested to see if there was any improvement if you allow only a specific angle and reduce the hole to just fit the camera. The air flow is currently optimised in the direction of thrust. Wonder if the main body would be better optimised in direction of travel. Would need to figure out what angle that would be at though.
Hey there, it might help to discontinue thinking of the rotors as providing thrust and instead refer to it as lift. This could help to change your thought process on builds. An interesting fact is that one of the fastest helicopters is the CH-47 Chinook. The Chinook is not very aerodynamic, or more so than other helicopters. What it has is a lot of rotor disk area. That gives it a lot of lift force. Helicopters generate thrust by creating a difference in lift force across the rotor disk(s). If there is a greater amount of lift force on one area of the rotor disk, say at the 6 o'clock area, than that greater force will want to spread out over the rotor disk. The lift force wants to be in equilibrium across the rotor disk or system of disks. The greater lift force in the example will move toward the area of lower lift force. The movement of the energy creates thrust in the opposite direction. Multirotors accomplish this by varying the lift produced at the various rotors. Essentially, the way to make a helicopter as fast as possible is to increase the size of the rotor disk and reduce the weight load. The problem with larger rotors is that they have a higher moment of inertia. That takes more power, which takes larger motors and increases the energy requirements. There's also the ability to increase the amount of lift the rotor(s) produce, but there's still a peak and diminished returns once you pass the peak. Another aspect of the helicopter is that the wind speed over the rotor blades cannot exceed the speed of sound. If they do, the air will detach and lift will be lost. That max speed can be calculated by taking the distance the rotor blade tip travels in one revolution and multiplying that by the RPH and dividing by the distance equivalent of one mile or one kilometer. The max speed will be the difference between that number and the speed of sound. The RPM output of an electric motor is the kV rating multiplied by the voltage. There's a lot more, but I hope this helps.
Interesting project. Do you know what your thrust to weight ratio is? Considering this is a rocket, you might want to optimize for minimal weight rather than crash resistance... after all, it's easy to make replacement parts, and even a thick wall will not survive this thing at full speed. Also perhaps you might consider a design with mirror symmetry rather than radial symmetry. Making it more plane-like where you have larger horizontal fins for lift could be an improvement, helping improve lift-to-drag.
there is a huge hole in the front taking most of unnecessary drag.. I don't know how experienced you are but why don't ju just hand catch or just drop the quad in LOS?
The hole is used for getting some airflow through the batteries and electronics and out of the back hole. Landing LOS was my plan initially but it's harder to switch from goggles to LOS than I thought. The quad still moves pretty fast and due to it being pretty small and symmetrical it's hard to tell what its orientation has. Plus you are a bit disoriented and blinded by the sunlight yourself after a couple of minutes under the Goggles. So just carefully dropping it at low speeds and altitude was a safer bet. A version 2.0 of this I'm starting to work on will simply have two FPV cams that can be switched through an AUX channel
You will likely have less drag if you add a small acrylic glass half ball over the tip where the camera is. You can likely source it from those coin operated machine prizes, they use them as containers for small toys.
Hi Dave, awesome build, maybe servo on tilt for camera and flip of swich extra channel and your in hover mode cam looking down ,more great videos, and please keep em flying!
Can you put a small gimbal on the camera? You can then alter it in flight for speed run/normal flying/landing on a 3 position switch on TX or on a scroller if your TX has one
I have been working on something similar for a while, have you looked at golf ball style dimples? Not sure if they would help at 300KMH plus maybe somebody knows.
You should try this with 5” gear.! The body wouldn’t have to be much bigger just bigger fins. So the weight increase shouldn’t be much compared to the power you’ would gain. For easier landings you could use angle mode when close to yourself and land “line of sight” .
To be honest I stopped telling people things are reliable just because they worked for me. I'd probably have to test 10 or 20 to be sure i wasn't just lucky and got a good one. But yes, mine worked perfectly fine :-)
Next time tke the 3.5 seconds and put a Highcutcj Filter or SOME sorft of EQ on that sound bro... you are killing 198613196 ears and speakers with the 27000 subs you have.... Dope video !! =D kinda have to work on the landing hahaha xD
Bro that was sick 😃👊 To land just pull your goggles off and land line of site. This might sound funny , if weight is an issue, make it bigger 5" or more with hi kv motors on 6s or more 😃👊 you can tell im excited for you , right? Bro its so cool. I got some custom batteries made last year. U could get some long ones made to fit rocket. You could run air unit in it. Record in hd and gps and have clear plastic cover over fpv camera , less air drag. I can see you getting Speed WR in the future bro 😃👊 Do you What the Speed WR is ? Bro you got this thanks for sharing
That was cool, I bet if you moved up to 5 or 6 inch the power to weight ratio would be much better, with something like 2407, 2506, etc, I think you might get a world record.
Nicely done...almost done with mine and like the slot you added in the nose for the camera angle . I made a launch pad and put it up on thingiverse but haven't tested it's stability yet...Have to wait until the parks open up again to get a test flight in...*sigh*...
since the weight is already high, maybe look into ducted fan designs that actually improve thrust. The ducts wont add much weight and you could potentially get some pretty good thrust improvement, though with high prop speeds, it may not produce much more if any extra thrust.
This is entertaining. Far as Landing goes I wound pull off the goggles and landed line of sight. Or enable auto level mode. Please keep this going I want to see more👍😀
Put gps inside frame. 1-2 mm of pla shouldn't affect signal, but aerodynamics will improve.

Great stuff man.
Love the 1408 motors...could they run decent on 3S?
3500kV is a bit low for 3S but sure it would run just fine with 3" props
Almost 160 mph! That rocks! Want!
Net landing like in drone raceing is what you want also if you made it fly 3d (ie make motor direction reversible) so it can air brakes basically.
You could try hooking the camera up to a servo, so you can change the angle on the fly, for landing, and speed tests, respectively.
That's awesome! Nice build, and some impressive results.

I would assume they do. But I don't know how significant the effect would be
Wow this is very very good
Maybe sand down the outside or add a thin coating? The 3d printing leaves texture on the frame which probably adds more drag then one would think.

Next time tke the 3.5 seconds and put a Highcutcj Filter or SOME sorft of EQ on that sound bro... you are killing 198613196 ears and speakers with the 27000 subs you have....
Dope video !! =D kinda have to work on the landing hahaha xD
AAAAAARGH the noise!!!!!!!!!! :-) Ace project though
cool :D , will you build a 5" version aswell?
Sweet, could you add GPS for height data and cut motors a few inches off ground?
Bro that was sick 😃👊
To land just pull your goggles off and land line of site.
This might sound funny , if weight is an issue, make it bigger 5" or more with hi kv motors on 6s or more 😃👊 you can tell im excited for you , right?
Bro its so cool.
I got some custom batteries made last year. U could get some long ones made to fit rocket.
You could run air unit in it. Record in hd and gps and have clear plastic cover over fpv camera , less air drag.
I can see you getting Speed WR in the future bro 😃👊
Do you What the Speed WR is ?
Bro you got this thanks for sharing
With more research and weight reduction this will be a good drone to fly .
Loved your 5" toothpick design, now this? Looks like I'm gonna be making one of these now lol
Look out neighborhood!!!! 😁
This is quite the design, not bad speed either, 159 mph!
That was cool, I bet if you moved up to 5 or 6 inch the power to weight ratio would be much better, with something like 2407, 2506, etc, I think you might get a world record.
Nicely done...almost done with mine and like the slot you added in the nose for the camera angle . I made a launch pad and put it up on thingiverse but haven't tested it's stability yet...Have to wait until the parks open up again to get a test flight in...*sigh*...
Hi. Fantastic design. I am building a similar one. Where can I find the .stl file? to use it as my base.
Thank you
Thingiverse. Look for my profile. Same handle :-)
since the weight is already high, maybe look into ducted fan designs that actually improve thrust. The ducts wont add much weight and you could potentially get some pretty good thrust improvement, though with high prop speeds, it may not produce much more if any extra thrust.
flight data is beautiful. I wonder if you can still optimize the design to reach the maximum performance.
how do you arm at such high core temp?
I have a quad refuse to arm at 75 due to VTX mounted so close to FC
The Mamba F722 does that alle the time even in other quads with good airflow bug I never had any issues with arming
Very nice build! Put you antennas inside your frame no need to be a outside.
Fantastically fast! Love it!
