Hi, Just wondering how can I maximize the flight time on my Trex 450. My motor arrived dead, so I managed to changed it with my LHS but was given a 3150Kv align motor as he does not have stock for the 3550Kv model. Was told it will work as well.

I am running it with a 15T pinion, and a 2100Mah 22C align battery. Any idea how I can make the flight last longer? Will a higher Kv motor with a 11T pinion work? or is it just a battery thing?
