Hi at all!
@ R/C-Plane: It´s 30 - (40) Km/h fast, and it fly´s, "at no wind", very underpowered.
@ Iroeine: Very, very nice idea, your thrust vectors. I will put it on my plane, too.
I fly the su 4 times at stock motor setup and i think, she is totally underpowered. Iroeine is on the right way, brushless and new fans. The transmitter and electronic is very sloppy, when you can order it without electronic, then do this.
But it is a beautyfull model.
