Hey guys!

I was talking to a friend a while ago and he said that some poeple used 2 receiver batteries. I though that was only meant for the giant scale guys but he pointed out that you could use 2 batteries on the same receiver for more speed and torque on the servos...I'm really not sure if this true or not..it does makes sense but i'v never seen the setup. I'll apreciate any info you guys can share! Thanks!

for a fully charged battery, it wont make a difference. 2.8 volts is 4.8 volts, you will just get a longer run if you use 2. it is little different than going from a single 700 MA battery, to a single 1400 MA battery, only your using 2, 700 MA batteries.

It won't speed up the servos, that's for sure. Higher voltage will, as in 5 cell pack instead of 4 cell. Many guys use a separate large battery for servo power with an isolator. I don't see much sense in it on a smaller bird.

I'll swear by a 5 cell pack, that's all I use in every profile, I make my own packs and use a 6 volt regulator to keep consistency. Search for MPI on this forum I'm sure you'll find their site, you can buy ready made packs and whatever else you need. Hope this helps.

Yeah, I'm 6v in all my stuff these days. Can't see any reason not to. It's more torque and speed.

I agree. A rx is set up on a paralell bus system. You could put 4 different packs on a rx and all it will do is increase your Mah(mili-amp hours). This will only increase you flight time and your weight[&o] and in 3d, wt is the enemy... If you want more speed and torque, go with the 5 cell pack as Gordo stated. Also, some servos will not take a 5cell=6vdc load. Find out your servo specs before you fry one...better safe than poor......
My 2 cents,

A signgle batt. is all you need on anything under a 120 size plane, but go with 5 cell and icrease you're servo speed. Allthough my experience has been when you use faster servos, you end up compensating with expenential which defeats the purpose. Just use standard servos and 4.8 batt. and go light on expo. D Boothe

Exponential has no effect on how fast the servo gets to where you want it, or how much torque it produces. Even if a guy does use more expo, that doen't by any means defeat the purpose of a 5 cell pack.

A standard Futaba gets over 25% increase in Torque, that can mean a big boost for a 40 sized plane with huge surfaces (seriously tightened the waterfall on my Knife, for example). And when you need that rudder NOW the little speed increase is helpful.

When I switched, I could see the difference. Took a bit of getting used to. I use less expo than I ever have, but that's because I've been weaning myself off of it, nothing to do with battery voltage. I have 5 cells in all my planes now, just like it better.
