I'm almost done building a synchropter http://lmgtfy.com/?q=synchropter
and looking for a flight controller for it . . . no luck so far.

Tried SK720 tandem setup and it almost worked!
Only 2 differences, rudder and elevator control
-Tandem Rudder : *Differential collective + *Differential Aileron
-Synchropter Rudder: Differential collective only
-Tandem Elevator: *Cyclic + *Differential collective
-Synchropter Elevator : Cyclic only
*At least what SK does

I couldn't find a way to do that.

Can SK add a synchropter mixer or a custom mixer?
I know it is too much to ask but I have to try

First take off attempt was the worst nightmare.
Forgot that the servos were at full travel for test.
Some aileron correction and its side on the floor.

Almost done repairing

BTW while testing some more
I found the phase trim has no effect on rudder for tandem setup.
If this is fixed SK will possibly work!
Also tail servo slot is left unused here. Why?

How's the vibration?
