Hey All,

I have a Highwind H4 frame,  I'm currently running 1306 3100kv on it and 3s.  I do feel that it's a little under powered.  I'd like to put some 4s capable motors on it, but I'm not sure which ones.  Seems like rs2205 has plenty of thrust, but it does weigh a lot.

Is it possible at all to have a 4 inch setup that can keep up with 5inch triblade quads?  I find my current setup to be the easiest to fly, it almost feels like it hugs around corners, but it does feel a little under powered.

I am running my Airblade Assault 130 on 3 inch tri props with 1306 4000Kv Motors on 3S and 4S with no problems at all. on 4S the motors get warmish but never too hot to touch.

It depends on the race course and pilot but 5" should be faster on the open and straights...
2600kv/2800kv motors work well on a 4" inch build
