Hi guys

I watched the video and your correct it is impressive, but where does it say what specifications his model is, I know you dont get a good idea of scale of the videos but that model is nowhere near 6.5lb.unless 20% nitro makes an enormous difference I cant see a ys 63 doing all that on a model that ways anymore than 5lb. however, when you are flying a 13x4W do you need to take care with the throttle to ensure that is does not over rev, because I had problems with the 14x4W over revving and the noise was just too much. not to mention the wear on the motor.
