Is 3 bateries to many?

[Riven]

how many bats does it take to start making motors fry? will 3? 4? 5?

Riven,

The Rx can handle up to 5v, so four cells or anything on a 5V output voltage booster is the absoulte upper limit for voltage. As far as frying the motors - the hot winds tend to fry at higher voltages, but the higher resistance motors can take it. A 1.6 or 2.2 should be ok, with any motor over a 2.2 you are pushing your luck with three cells. Some pager type motors are actually designed for higher voltages (check www.didel.com ). It all depends on your objectives.

so u are saying i should stick with 2? hehe

Here's how it works.

1 cell to 2 cell
"HOLY CRAP!"

2 cell to 3 cell
"oh, thats nice, I guess"

3 cell to 4 cell
"do you smell something burning?"

4 cell to 5 cell
"can you help, my pants are on fire"
