I'm new to this hobby, my other hobby is stock car racing (dirt latemodels). My question is I'm now flying mini edge 540 from e-flite. There is a square hole about 1/2 way back on the bottom of the fusealodge, can I put white covering over it or will this cause the motor/speed control/battery to overheat or damage them. I'm using the recommended motor/speed control/battery. Any ideas and opinions are welcome.
