ive had a qx65 for a while now. the stock motors and batterys gave out. i got 25000kv motors and 2.0 battery connector on it now. i was wondering what is the max battery(physical size and mah)i could get on there. i currently hase some 260mah stock size that i only get like 1min 30sec flight time on. i was thinkin like a 450 mah like from an tiny hawk like that kinda battery. would it be too heavy or wood the new motors handle it. in just looking for longer flight time not better performance, i dont do acro moves or anything with it just fast flying around and dives. nothing crazy.
