Hi Guy's, I would like to know what you all think, Is running a 6v a lot or only marginaly better than 4.8v?? I have been running 6 volts because of the extra torque it gives the servos plus I have been told they are better safety wise as if you lose a cell the plane will still fly on the 4.8 volts that remain.

Problem is I bought 2 Hitec 645 MG servos but when set up on 6v tended to twitch and after asking those who should know was advised that Hitec don't recommend them for 6v, something to do with the pick up feed wire??

These servos still have heaps of torque at 4.8 volts which is plenty for the plane I'm building (Cmpro Eagle) but not sure if going back to a 4.8 v system is a good move or not.
I have to say that my first large plane (Pacific Gee Bee) was only set up on 4.8 v without any apparent problems although it is only a fairly easy, non aerobatic plane that doesn't put too much load on the servos.

Any input from you guy's would be very much appreciated

Rgds,
Rod.
