Can I use INAV to build a bicopter?

Yes, you can build a bicopter (2 props, 2 motors, and 2 servos) with INAV. It's more than possible, and over the years I've built several of those. But, INAV support for bicopters is not the best and is missing some features like selective Angle mode for one axis and logic for better handling the gyroscopic precession.

Great to know, Pawel! Thanks! 😃
Stay safe there with your family! 🖖😊
Love the idea of bi copters. Are there any plans of inav supporting vtol in future?
cool. Looking forward to it!
my inav bicopter is semi stable - hovering is ok, but a lot of pitch drift and beware of to aggresive inputs. very interesting mixer fact: you have to compensate yaw/pitch movements with a litte bit of more thrust otherwiese the copter will lowering. so I'm now waiting excitedly for version 5... a lot of thumbs up
Oh man to have an RC Chinook or an "Aerospatiale SA-2 Samson" from Avatar that operate smoothly aswell as fullfil that amazing scale look, wow. I'd love either one but the Chinook or even the Osprey but being Canadian myself I'm impartial to the Chinook as it was manufactured by Canadian born company Boeing.
I know I added a 'vote'(?) for it some time ago, but Ive never been able to understand the way the iNav dev pages/wiki (I dunno, grasping at straws even here!) to find out if successful or not...
BUT, did the servo feed-back code ever get implemented in iNav for use on Tricopters?
It was a fork of both iNav & BF were being worked on by the RCExplorer community & was looking quite promising...
(Which reminds me once more- I MUST get my Tricopter finished one day! :v )
I know they were also working on a Bicopter with servo feed-back for a while but I wasnt following that too closely....
Best of luck with this latest project! :D
love this. Now I want one. Would it not fly better if orientated so it flew like a chinook? Or would that make it "skid" due to yaw control mix? Have you tried this way?
Im game if you are!
He he he... when weather settles I'm testing new version :)
Cześć, mam problem z copterem. Przeszukałem już bardzo wiele jednak dalej nie mogę odnaleźć przyczyny dziwnego zachowania drona. Mogę się jakoś z Tobą skontaktować i opisać o co chodzi?
Pozdrawiam,
Szymon
How did u configure it im working on a similar kind of project
Hi sir i am your fan because of all your review about using inav i learn to much. I want to know if i can use gps module without using compass on rth failsafe on Quadcopter. Same like gps rescue on betaflight. ?
No. INAV has RTH not rescue and that needs compass
@@FPVUniversity thank very much
At 1:16, the reference to "gravity" is irrelevant; this stabaization topic is better known as the "pendulum rocket fallacy" (which applies to all aircraft, including drones, not just rockets).
The true reference is centre of mass (or centre of gravity, of aircraft) and the relationship of thrust angle to the centre of mass.
For stable flight, the centre of thrust must pass through the centre of mass. Even on winged aircraft.
Actually it is relevant. Because combined gravity and thrust vector create a torque that allows to change the orientation in space. Pendulum rocket fallacy refers to passive stability, not active orientation control
If your brain tends to want to reject the distinction Pawel is making, consider the last sentence "for stable flight the centre of thrust must pass through the centre of mass". Yet we have millions of planes and MCs flying around just fine with the thrust vector not quite aligned with the CG! Some are nowhere near the CG. How is this possible? It works, our planes actually fly, because Inav actively stabilizes them. It's not an uncontrolled model rocket that depends on static stability.
Ps - parachutes, including paramotors and powered parachutes are very stable in pitch. Why? Because while the pendulum effect is small in standard planes, it actually *does* exist.
@@senseisecurityschool9337 There is more to flight dynamics that CG and thrust angle. All forces, including forces produced by control surfaces, and other lift, drag forces need to be accounted for. (pendulum effect is not one of them)
Gliders, and paraglider actually produce a forward thrust vector, which coincidently passes near the centre of mass and the centre of lift.
Good luck trying to explain how the pendulum effect works for a glider, or parachute during a loop, or roll.
@@AerialWaviator "good luck trying to explain how the pendulum effect works for a glider" - as I stated, it's not a significant effect for a glider (speaking in terms of one shaped more or less like a traditional plane). Source - I design and fly gliders.
On the other hand, good luck trying to explain how thrust angle is the primary determinate of stability for an unpowered glider or parachute.
On the other hand, for a parachute the center of lift SO much higher than the CG that it becomes significant.
Lastly, with a parachute, the lines are not rigid in compression, and are attached by moveable joints. So whatever you think you know based on a solid body may no longer be true. The parts can move *relative to each other*. That makes some things different in ways that would be very surprising if your mental model is a rocket or plane.
I was disappointed, I thought the "Bee-copter" would be a new and exciting thing, but turns out it's just "Bi-Copter" with a Polish accent ;)
;)
The real question is can Inav support a tricopter? Because I’m in process to build one
Yes!
