extra reciever power?

[RobH]

All of you have seen the torque and speed ratings for servos. You have one set for 4.8v (rechargeable AA's) and one for 6v (hump packs and normal Alkalines). We all know more voltage means more power and speed. That's kind of obvious.

Voltage isn't a specific thing. I know you can put a little more voltage in most things and it's no problem. I always thought 6v was as high as you should go with voltage to the receiver and servos.

I was reading another thread where a fellow had 6.7v or something because he was using 5 rechargeable AA's. The response was that's fine. Plus or Minus a certain voltage is fine. what about 7.5 volts? Is that acceptable? Has anyone tried using 5 AA Alkalines (7.5v) instead of 4 AA Alkalines (6v)? Some electrical person must have thought of this already. Does anyone you know use more than 6v for the receiver and servos? Am I adding more wear and reducing the life of my servos and receiver by using a higher voltage?

I'm guessing M@xximillion must know a thing or two about this. I'm sure, however, he's a busy guy.

Any info you can add would be great.

Thanks,
Robert

I believe when you put more than 6v to a receiver you take a chance by frying your receiver. Unless, your receiver has a BEC. Your best bet is to use a 6v rechargeable 5 cell hump pack.

I got all excited when I saw the 7.2v battery pack in a news post on the front page this morning. Come to find out it's for those micro R/C from HPI. I could also try putting an extra AA in and see what happens. I have an old traxxas reciever I don't give a crap about.
