Would like advice on this.
I plan on using the Futaba s9206 servo for the swash function. This will be in the 120 degree rather than the 90 degree.
I would like to run the system from a a 6 volt supply.
Is it ok to have a voltage dropper between the rx and each servo or is there a better way.
Thanks.

Better Way

I personally would eliminate any unnecessary equipment that may cause failure. Just run 4.8 volt, and increase the capacity size. Or switch to 9202's which are plenty of power for that size Vario and use the 6 volts. Why risk it. Hope that helps, -Adam

Thanks Adam,
A few people have said that the 9202 is ok for this but at around 69 oz it seems a little on the light side for moving four blades.
Have you experience of the BK117?

Im with Adam on this. The 9202's will be fine on the multi head. 9206's at 4.8v are more then up to the task as well. I've flown both with great results

Four blade head

Hi reg, look in my gallery, my Vario ec has the same 4 blade head you are using, is about the same size, and I'm using the 3 servo 120 with 9202's and it works great. Remember your not looking for 3d movement on these servos, just holding torque. 9202's work great for this application. Hope that helps, - Adam

Thanks guys for your input.
Adam, that is one impressive helicopter, I sometimes feel a twinge of envy at the feedback you must receive at your meets.
9202 it will be, as you say, why risk it.
Thanks again
Reg
