VTOL RC Airplane 65 (dRehmFlight Test Flight) #rc #f-35 #vtol #teensy4
I even flew it using the dRehmFlight gyro.
It has different characteristics from the previous gyro, so I think it will fly well once you get used to it.
I think I need to practice controlling the airplane a lot in transition mode.

I installed a new gyro based on dRehmFlight data from the Internet. The instructions and video were well made, so it was easy(?) to follow along. It is more stable than the previous gyro.

All preparations for flight are complete. The landing gear was reinforced for STOL. I looked into flight controllers for the gyro, but there was nothing suitable.

Following the last video, flight tests are in progress. The wings were short, so I added strake, but it didn't work out well. In the end, we solved the problem by redesigning the wing shape.

Nice work!
Hello ,I am trying my best to figure out how to build a vtol similar to yours , dressed up as a harrier ,what is the best way to set up a reverse y in Inav if that is what you are using?
I can't give you an answer because I don't know anything about Inav. I hope it works out well.
Hey, you know Vtol means vertical takeoff and landing, not whatever that is
It says stol not vtol
Bery very creative
you should try an f405 wing mini its pretty good just need to learn inav or ardu pilot its not super easy but a few videos and forums helps a lot with setting it up
Indeed! I used exactly that (speedybee f405 wing mini and iNav) to build my own vtol. Capable of full inbound and outbound transition: ruclips.net/video/MhnkgsEyRRo/видео.html
flys without nose!
btw, the use of CF rod/tube in an application where it will be subjected to torque is not recommended.
WHY can't you see that DESIGN should result in a most-stable dom.! WHY can't you see that locating the mass of several servos aft-of the cg, and outboard, results a less-stable dom.! the cg should be located at thirty percent of mac. so, identify the mac and project a line at thirty percent to the wing root.!!! the c-m should be located (in the fuselage) slightly forward-of the cg line; at a point that aligns with twenty-five percent of mac. when you know where the cg/c-m Should be located, to the extent practical, 'arrange' mass concentrated in that zone. think of the dom of the entire model as a horizontally oriented teardrop 'shape'. see the Deliberate use of an elongated teardrop shape, in the fuselage of a typical ga lightplane. obviously, the application of these design rules to a delta/highly-swept wing requires some 'finesse'. you may know that, as a result of design constraints, the cg and c-m are 'nearly coincident' in some jet fighters. in that case, the aircraft will be susceptible unrecoverable flat spins. it is not known whether your model has this issue. googletranslate
thank you. I will take note.

안녕하세요! 혹시 컨트롤은 아두이노로만 하시나요?
처음 시작할때 컨트롤 보드가 따로 있다는걸 몰라서 자이로와 아두이노만 썼는데 지금와서 바꾸기도 그렇고 적응도 해서 그냥 사용하고 있어요.
@@a9rc 와우 정말 대단하십니다!!
I WILL SAY IT AGAIN there are things you could do to 'improve' the distribution of mass (dom). including, moving the mass of THREE servos nearer to the cg/c-m. c-m is center of mass. the use of bellcrank linkages would allow the OPTIMAL location the mass of the elevon servos; eg., nearer to the c-m and to the center line.
hay dude....can youplz provide your ikarus piccolo helicopter main rotor exact length and width?
I left out the Icarus rotor, but I can't find it. I am using a different rotor, but when compared, it would have been around 238mm , 40mm.
@@a9rc Thanks...this info is enough for me....

Man!!! that's so awesome. Stick to it and you'll succeed.
Thank you..
PROPELLERS, that are Sufficiently STIFF should be used.! you refuse to SEE what is in front of your face.!!! this is a design that necessarily has a Lot of mass, located aft-of the cg/c-m. therefore, the mass of three servos ABSOLUTELY should NOT be located aft-of the cg.!!! the locations of the cg and c-m are not supposed to be coincident. if they, ultimately, are there will probably be a major shortage of control authority. in other words, you NEED to KNOW where the c-m IS.! it should be located slightly forward of the cg. it is useful to think of correct distribution of mass (dom) as a sideways Teardrop --- one that is 'centered on' the point that is the ideal/optimal location of the c-m. d
I'll refer to it.
The transition must be slow ;) .
full video ruclips.net/video/wGP1jPu_k6Y/видео.html
suggest that 8-blade rotors be tried. ruclips.net/video/i58cC2hntqQ/видео.html are you still stoopidly using two coaxial rotors at the front.
I've already tried it, but I don't have the strength.
1:03 when an entire flight surface is articulated, the pivot point should be located at the neutral point. which is that is located, more or less, at twenty-five percent of chord / mac. also known as the 1/4-chord point. googletranslate
:01 this model STILL has a heavy tail.! because, in addition to the mass of the main wing, two motors and other stuff, the MASS of three servos is AVOIDABLY located aft of the cg/c-m.!!! a wing profile that is Optimal for the application and flying environment should be used. aka a very low reynolds number (re#). it is not undesirable that a wing make less lift, near the center line/fuselage. consequently, the use of a nearly symmetrical profile at the wing root is not a mistake. the rest of the wing, however, should have a profile that resembles the n-10. the shape of the nose is Very Not Symmetrical. :08 the use of CF in the design of an ACTIVE component, for example in landing gear, is a MISTAKE. the use of two coaxial props is a design Mistake; one that DOUBLES the mass.!!! suggest that a single edf-type impeller be tried. do you yet understand that, when the blades of a prop are 'more' flexible, they tend to 'unload' at higher rotation rates.?!?!? said another way, the amount of thrust produced by a prop that has flexible blade varies with rpms, in a way that is less-than obvious. it seems (to me) that, in order for a multi-blade prop to be efficient, the use of a 'greater' pitch value is needed. obviously, the performance of each propeller blade is affected by the amount of turbulence -- from the passage of the preceding blade -- that it encounters. googletranslate airfoiltools.com/airfoil/details?airfoil=n10-il obviously, the DESIGN of the fuselage should Result in enough enclosed space, to contain the Battery etc.!!!
Reducing weight is great.
👍🇷🇺
I've been watching since part 12, I really admire your dedication to this project
Thank you for watching for a long time. I think it'll be done in a little bit.
Респект за Российский триколор🇷🇺!!!
LOL
DISTRIBUTION of MASS (dom).!!! you still get an F, in dom optimization.!!!
Subscribed!!!!👍👍👍👍👍👍👍
thank you.
What’s next can’t wait ! Become a YT god > 'Promo sm'!!
The model looks great 👍
Arduino has slow CPU, use teensy instead. Nicholas Rehm's FC is perfect for this project
I'm used to Arduino, but I'll look for it.
you continue to FAIL to optimally located the mass of the elevon servos.!!!!!!!!!!
2:29 it appears that the wing profile used is nearly symmetrical. if so, then the ENTIRE wing will need to have positive aoa/aoi. in that case, the aircraft will be in a nose-up attitude, ALL THE TIME; and, wing will make More drag than if a WELL-chosen low-re# profile were used. compare the n-10. 2:44 this is NOT enough wing area. if you can determine the virtual root chord length, cg should be near fifty percent. at the same time, to the extent possible, the c-m Should be located a bit forward of the cg.!!! center of mass
2:02 finer control needed. suggest that more reduction at the servo output, be tried. this would give the servo more MA. mechanical advantage.
:55 the forward upper hatch(es) will act as a GREAT BIG AIRBRAKE.! if you don't care, fine.!
Nice try! I have the same one but learned that one touch acrobat button is useless! It just does not roll. You might need to trim out a bit by pressing down trim button, so it'll fly better and faster.
and the plans?
Unfortunately, this flight is no longer in progress. I'm focusing on VTOL.
Very Great Good job, Can you share the plans please so we can have the amazing plane
Unfortunately, I can't find the data because it's old. I think I quit because it was hard to make.
You've come so far since I started following your channel! Good job. It's very smooth transitioning, flying and landing. I remember some videos where it didn't work this smooth.
This is so cool! Nice work. Please try and capture a slowmo version of that final shot of the short take off with the dust.
Finally worked
대단하십니다!
What is the total cost of plane
It's about 400 to 500 dollars excluding receivers.
nice job
good
It flies better and better, maybe open the door to the sides left and right ?!
It's a good way, but I'm worried because there are a lot of things to change.
A transition! 👏🎉
niiiiiiceee!!!!!
Well, great to see it still intact! Youve done a good job refining the design and piloting it!
