As I read this, the talk of 8000 and 6000 batteries leads me to belive you guys are running maxamps packs. Do not buy the 6000 pack and expect it to work well, it is made of a 2p configuration of 3000 cells which are 12c cells at best. All of ma stuff drops voltage quite a bit under load. And their prices went up, so buy flightpower, neuenergy, polyqest or polyrc batteries. They are all made with enerland cells, best tested on the market right now. They will give you longer runtimes and more punch, and will most likely last longer. I had a bunch of maxamps stuff, and have recently changed over. Huge difference. A 3700 polyrc 5s pack can outdo a maxamps 5000 5s pack, punch, runtimes, everything. A pair of trakpower hardcased 4900 2s lipos will outdo a pair of maxamps 5000 2s lipos, in fact a huge difference! And if you plan to run 3s, you will need good batteries, as the amp draw is higher. That is why 4s is better, and will not add weight, just improve temps.
