Some of you guys have a power box in her plane. From how many servo's you need this power box?
In the DV8R there will be 8 servo's for only control of the rudders.
Each 2 servo's will be connected to a Y-wire and than to the receiver (2 servo's for elevator ---> Y-wire ---> receiver, 2 servo's rudder ---> Y-wire ---> receiver, 2 servo's ailerons --> Y-wire ---> receiver, 2 servo's flaps ---> Y-wire ---> receiver.)

Whit those 8 servo's i didn't count the servo's for retracts, brake etc etc. The rudder function will even have 2 Y-wires to 1 receiver connection., because i also need to connect the steering servo of the retract. I think i need 3 or 4 extra small sevo's for those extra functions.

I need all those Y-wire's because i have not enough connections to my receiver and transmitter.
I have an Field Force 9 from Futaba, and this only can control 8 functions.
The functions i need are; 1:rudder 2:elevator 3:flaps 4: ailerons 5: retracts 6: brakes 7: engine switch 8: engine control

Can i feed al those servo's directly from the receiver, or do i also need a power box?

greetings Paul
