I'm building a T-copter. The goal is aerobatics and FPV. I know a higher Kv, shorter prop is going to give me more aerobatic ability, but I'm also looking for efficiency in flight time for FPV.
Here are my current choices:
SunnySky 1400kv, 8047
real good response and thrust + smaller rotor = more stability for hover. A really aerobatic machine but only maybe 7min on a 2200mah loaded with FPV equipment
SunnySky 980kv, 9047
the maths claim 15% more efficiency, slightly less thrust, larger prop = less hover stability and less responsiveness but more efficiency.
I'm aiming for at least 10min FPV on a ~2700mah. Ultimately I'm not sure the g/w efficiency really matters because the quality of the motors are similar and I feel as if more weight = less fly time no matter what kinda motor/prop config you're using. I only really see it making a difference when you get into 6+ motors. Is this notion correct? Should I not worry and just go with the 1400kv?
