Will the Micro Brushless Rally
run okay on 2S or 3S LiPo packs? The pack it comes with is a 4.8v NiMH, so a 2S at 7.4 seems a little high and a 3S at 11.1 seems insane... but the manual on their site has an optional parts list and both of these batteries are on it.
An internet search turns up people having problems with 2S (servo works, esc won't spin motor), but 3S working. But I can't tell if these are the old vehicles with the optional brushless upgrade or this one with it already installed.
