As a newbie to rc have a maverick vader and I am using 3200mah 3s lipos and I only seem get about 20 mins of run time, is it better to get something 3s with a higher mah or 2s with a higher mah not sure which would be better, as in the manual it talks about running it on lipos but not which ones, I just got the ones that were recommended by the store. Any hints or tips would be gratefully received thanks
