And please tell @Walter that he is still a very smart person 
and deserves the bonus that you had in mind for him at the end of the year 
Nice zoom camera, what camera is it?
I didn’t understand your circuit diagram, could you make the circuit diagram more clearly? Thank you
What you do not understand ?
Yes, I have a problem with my circuit board. Thank you.

Looks really well you do the same as me FBWA to QHover and let if slow down. I will have to try my transitions a bit lower next time .
What camera are you using for the on board footage
David Ardis
An old Mobius actioncam

Some successfull testflights with arduplane 3.9.0beta5 this weekend:

Dear Rolf, what power modules did you use?
tks
These are quit ordinary power modules for Pixhawk

Hi Rolf
Thanks for sharing your nice job. What I’m afraid with this is…is not adopted for tilt rotor type VTOL because rotors should be shared by copter and plane mode. Am I right?
Yes. At tiltable motors you would need a switch. Whether the possible advantage is worth a high current switch ? i don’t know.
Rolf
Thanks Rolf,
Is there any “Switch” for tilt type VTOL except Foxtech? ( which I think is over priced ^^; )

I have no idea if there are good relays, for example.
Our next tri-tiltrotor vtol should have only one front motor tiltable ( Reverse Tricopter-VTOL Plane )
Both rear motors are just for hovering and will get a separate battery.
it would be interesting !
Rolf, thank you very much for sharing your models. Let me ask you something: Why the flight battery and hover battery are connected in the negative wire?
Regards,
Because the voltage reference needs to be the same. Without this bad things will happen.

Hi @MolettoLobos,
as @amilcarlucas already wrote, it is important as common signal ground. The voltage drop should be as low as possible. The cable should therefore have approximately the same diameter as the battery cables.

@Rolf In your arrangement, it appears that the VTOL battery powers the FC and the Flight battery powers the servos.
In my build configuration, the Flight battery powers the FC and the servo rail (separate BEC’s) while the VTOL battery only powers the VTOL motors. Is it possible to use the VTOL battery as the backup power for the FC in case the Flight battery fails? I intend to use a BEC for the VTOL power so that voltage is monitored even if it isn’t a backup power source. FYI - I am using a Pixhawk 2.1 cube and Mauch power modules.
This would be a question for @pompecukor as well since it is a hybrid power setup.
Cheers,
Christian
