RE: TP 4200 vs. TP 5300 LiPo Batteries
Hello Xavier.
I do not know how the altitude will affect your battery consumption, but using TP 6000 mAh packs in a model weighing close to 5 kg/11 lbs (at sea level) I regularly consume between 4000 and 4500 mAh for a P07 flight. In my model, with my flying style, the 4200 mAh packs would simply not have enough capacity.
