I am running a Y with reverser in my Funtana 90 for the elevator servos. I have 12" extensions and a 4.8v, 1500 nimh pack in the nose, also on about a 12" extension. The slaved elevator half has centering problems, as in it is slow to find neutral after any deflection in either direction. I am wondering if running 6 volts would solve this problem, or if I may need better servos. They are hitec 425's. The second part to this question is how do I know if my receiver can handle 6 volts? It's an older model 7 channel receiver that came with a hitec challenger radio. My transmitter, an Eclipse 7, won't handle seperate elevator hookups to the receiver, so I need to run the reversing Y or two opposing servos and a standard Y. Thanks for the help!!!
