RE: does everyone here use lipo?
TommyGun... you use a 3S 11.1 lipo in most TX's. I love the one in my 3PMFASST. I go 5-6 months without having to recharge, and ive still never seen it drop below 11v. I use a CommonSenseRC 2800mah 3S pack.
No electric vehicles for me to use LiPo's. Though, i have successfully used them as RX packs (2S regulated to 6v) and of course TX packs.
