This is a beast!! Nice work. I haven't built any 100+mph planes this size yet. I've built a V tail that had a 29" wing span that hit 115mph with a 40 gram gps mounted. But I think I will soon. Thanks for the inspiration!
Thanks man! The goal for this design is to hit 150mph (242km/h) and doing 226km/h at best led to my conclusion to (painfully) redesign the entire wing, and by that, the entire fuselage, but keep the tail original. More on that in the build process video!
all your fpvs are amazing bro, i was trying to learn how to make but alot of the videos on youtube dont go into depth on the wiring (its prolly so simple). would be cool if you made a video how you wire them up for noobs
Its always refreshing to watch your videos sir,keep it up please. On another note the road you land on does it damage the under carriage in a short period of time? And props.
The undersides are reinforced with ducttapes for durability and has worked for years without retaping/replacements. The prop has a 'Brake' feature and won't break upon landings.
Looks like you’re having fun and it’s very cool to be doing something interesting and different from the majority! Although you must have also seen the most recent TBS release. Yours seems more practical and probably handles better IMHO. Just curious, what is the reasoning behind the swept wings? What are low speed stall characteristics? I would think that high speed stall would obviously be at higher power settings and be very similar to low speed power on stall characteristics. I would think it’d be very important to test this so that you could bank and yank at speed. You also end up at relatively high AOA when recovering from unusual attitudes. I would think that a straight wing would perform better in all aspects. Very cool project!
Thanks Spike! The aircraft was fun to fly indeed (disassembled it for a straight wing replacement) The swept wing idea came from former Reno Air Race warbirds like the P-51R "Miss Ashley II" or P-51D "Vendetta" which were Mustangs modified with Learjet wings. Those were my source of inspiration for the Swept Wing design. It's symmetrical airfoil explains the relatively high AoA at cruise speeds & landing the plane could be done with quite a low speed as well (which I was surprised about with a 1.41m wingspan w/ symmetrical airfoil, no flaperons & 2.6kg AUW) - although, I haven't stall-tested it, but it definitely felt stable enough after loop-stalls.
@@AeroStuffFPV I've never heard of any benefits from wing sweep under the transonic regime. will be interesting to see how the straight wing compares. with such a high speed envelope, makes sense to use a symmetrical foil. Even some supersonic aircraft use straight wings. The sound barrier does not scale. What is a loop-stall? I've never heard of it? are you talking about a wing-over?
@ I meant the wing-over, but couldn't get to the name. I bet the straight wing with reduced wingspan, but same chord & type airfoil, results in less wing-area & drag and will def. contribute to speed increase. I've an APC 16x16 prop in mind, sized down to 14x16, for better speed-performance but might be a challenge at by unexperienced torque-roll after hand-launch
@@AeroStuffFPV I wonder if some type of wingtip design is best for high speeds? It would be the only other way I can think of for squeezing out a little extra speed. certainly nothing large, but maybe. a rounded tip.. start by looking at other high speed aircraft. maybe a rounded fairing at the tip.? not sure if there is some aero benefit, or just a convenient place to put fuel tanks on some aircraft..? the square prop cut down should work well for speed.. and yes, it would technically be over square once cut. if you are interested in speed, you should also watch the Arnold documentaries about the speed record little EAA plane. some area ruling application might serve you well, at least some version of it, which he explains, even at sub sonic speeds. has to do with the overall pressure gradient.
I believe a Pusher will be less ideal for high speeds because Propeller Efficiency is mandatory and pusher props deal with turbulent wake/air caused by the structure of the aircraft. At high speeds, the drag increases too (especially with this square-shaped fuselage) and by that, the standard pusher propeller will be ''overwhelmed'' by the drag-forces and decrease in effiency and will increase in noise. If this plane had it's prop located behind the tail, I personally believe it wouldn't be as fast, and be noticeably noisy at high speed attempts.
There's something magical about that plane. How can you get that speed fro a 600 kv motor ?!?! I have a light weight wing with a 2400 kv motor and a 3 blade prop that couldn't keep up with you... granted I'm onlt 3s and my motor is screaming but somehow yours is really quiet and just moving .... wow. What's your secret ?
Nothing special here. A 12x14 Tractor Prop doing about 12000RPM, compared to about double the RPM and significantly smaller prop, which tend to be noisy in general.
Well, that airplane with a weight of 2.26 kg, speed of 200 km/h and even doing a wide turn of 100m radius would be experiencing a G Force of approximately 3.15g. To put 3.15 g into perspective: Formula 1 cars: up to 5 g Typical aircraft turns: 1.5-2.5 g Space shuttle launch: up to 6-8 g
Not fragile at all. This has been a standard way of securing a wing to its fuselage in model airplanes for decades. It may not look the prettiest but it performs its function well. Also the plane in the video *obviously* performs very well.
The video about the build process is in the making. Stay tuned💨
EDIT: Build video will be released in February
I am waiting👌🤙👍
@MuhammedAlparslanAsar me too ;)
No fpv feed record? Bummer. Nice and quiet!
The speed is insane🤯🤯
Good filming! I like the low passtrough.Enjoyed watching this. Thanks🎉😊
Dude you got guts. Fast as hell and blue for blind pilots. Wow
cant wait for the build video, your builds are awesome!
It'll be released in March!

@AeroStuffFPV I figured out after 100mph it gets a lot harder. But yeah. It will have to be a whole new design. I can't wait to see it!
That's wicked. Love it!
Very nice👌🏻
Sir kindly make its construction video please
looks great! I just built a vtail pusher based on your design
very fast plane, cool build. thanks for sharing
That was awesome ...super fast 👏
Can you make a tutorial video on how to connect all the electronics in the trunk? I really like your videos.
Could you release a video how you complete the electronic system of the fpv
all your fpvs are amazing bro, i was trying to learn how to make but alot of the videos on youtube dont go into depth on the wiring (its prolly so simple). would be cool if you made a video how you wire them up for noobs
Thank you! I'll consider making a dedicated video about the electronics used in my planes.
Take a look at the Flite Test “Beginner Series” videos on electronics, as well as the various “wing” flight controller product pages.
Sehr gut 👍🏻

@@AeroStuffFPV Oh, and the Arnold plane used an over square prop too!!
I hope you make a video on how to build this plane.
太棒了，速度真快，后掠翼非常棒。
this is great stuff !
is the frame cardboard ?
Thanks!
It's 5mm foamboard, reinforced with woods & carbon tubes. Carboard doesn't survive +220km/h
@@AeroStuffFPV haven't you considered cardboard ? like for long distance v-tail one ? maybe it will help for more records.
Hello can you tell me which transmitter you use for these uavs
Approx how much all this parts costing to do some kind of FPV like this one ?
About 200$ for electronics alone, including a flightcontroller.
@@AeroStuffFPV including the battery?
awesome))
Why did you choose tractor configuration? What do you think about pusher propeller configuration for that plane? Thanks
I believe a Pusher will be less ideal for high speeds because Propeller Efficiency is mandatory and pusher props deal with turbulent wake/air caused by the structure of the aircraft.
At high speeds, the drag increases too (especially with this square-shaped fuselage) and by that, the standard pusher propeller will be ''overwhelmed'' by the drag-forces and decrease in effiency and will increase in noise.

@AeroStuffFPV thank you for explanation.
Last question: what flight time have you achieved on that battery?
What's the motor and prob used?
build video?😅
There's something magical about that plane.
How can you get that speed fro a 600 kv motor ?!?! I have a light weight wing with a 2400 kv motor and a 3 blade prop that couldn't keep up with you... granted I'm onlt 3s and my motor is screaming but somehow yours is really quiet and just moving .... wow.

2.6 KG? Dang that's pretty heavy.
电机有没有下拉角？
No
how can he be so quiet ?
I hate the rubberbands looks too fragile
Well, that airplane with a weight of 2.26 kg, speed of 200 km/h and even doing a wide turn of 100m radius would be experiencing a G Force of approximately 3.15g. To put 3.15 g into perspective:
