Stable hovering, little "pendulum". Nice design.

As you say : we want to see the transition, the trickiest phase for a VTOL.

What controler are you using ? gyros and Program Tx , KK or multiwii FC board ?

Good job

I use Gyro and Tx progam,the video it'is really the first attempt outside garage and CoG it's exactely under the lift vector of the engines so i have to move the lipo a little bit forward (i think) to reduce pendulum in Rome Italy ,the forecast its very bad;i hope in W.end the transition will be tested and filmed too.
Tks for your apprezzation and sorry for my poor English
Stay tuned,regards

How many gyro are there ? 2, 3 ? , angle between gyros ? 90, 120 ?

What sort of Tx prog and mixer are you using ? Plane, Heli ?

At the moment I'm building a prototype with H2 heli tx mixing :
-for the two front motors (pitch and aileron channel behind two gyros 90 hovering only ) ,
and a rear pushing motor ( throttle channel) with 2 servos (yaw and elevator) the tail being a close copy of the polaris's one.

Adjusting the throttle/pitch curve and playing with 2 different idling curves, I hope I don't have to move the front motors for forward flight.

Thanks for the congratulations and for your interest in my project ...
This device is very simple: the motors rotate on a shaft in carbon tube
8mm diameter: channel 4 (rudder) moves the tubes, channel 2 (elevator)
moves the servo that moves the channel 4 servo (mechanical mixer) and Channel 7 moves across the base of the mixer causing the forward tilt of the engines.
next time the block diagram and some pictures.

very interesting ,, especially the mechanical mixer...but that is what I started out with and really it did work the best for the area I used it on as I could get more conversion throw with the mechanical setup than with an electronic !!!!

All what we have to do,is to wait that Markusab,have a nice transition with the plane.
I have to admit that plane only with mechanical mixing,it hover really stabile..
Best regards
