Multiple servo wiring

[Stuart Palmer]

I am using multiple servos to control the elevators on my Pitts special, two hitec servos that will have the control arms connected by adjustable linkages. The servos don't have the high voltage connection so they can't be connected directly to the battery.

I am unsure how to wire two servos on the same channel without overloading the receiver with the current of two servos. Basically, I didn't think it wise to solder two servos together on one coonector into the receiver. Have you done this, did it work or did it fail?
How have others gone about this, what are your suggestions?

Stuart,
I often have 2 servos on a control surface on my planes. I agree with you that it is not good to use a simple 'Y' lead. I use a 9 channel receiver and then use a seperate reciever channel for each with a simple mix from the primary channel.

You can aslo make yourself a seperate power feed for servos so that the current does not go through the receiver. If you look inside a receiver you will find that the row of pin connectors for the servo wires are all directly connected. All the +ve and all the -ve pins are simple connected across to each other on the circuit board. Hence connecting them together outside of the receiver is fine.

Thanks Andy

I set up a spare receiver this morning with two servos as you suggested. I think it will do what I need.
Thanks Andy.
