poor quality battery may also cause the fets not open\close as they should, atleast so have i heard. Turnigy is one of the more common batterys out there so i recommend tekin to get some suitable ones fore testing purpose.

As your affiliated with the manufacture and prob have allot of knowledge(atleas more than me) im surprised you are blaming the battery and claiming lower capacity ones can deliver more power than the bigger ones

dont think this thread was meant for blaming ore find the reason just for showing off like yes i burnt the rx8
