Nice looking plane. however an 8 pitch prop will be far from 115 MPH. It will be lucky to hit 100. A 22x10 might get you near 100, a 20x12 will get you around 115 a 18x14 will get you too 125mph. This is of course if your engine can turn these props at around 7300rpms on the ground.
I saw a T/F today with a 22x8 fly. It was very ''scale like'' around 85 mph.
My mustang flys at a very ''unscale like'' speed of 135mph. G-62 with T-6 racing prop on RCexel ignition. turns 7600 on the ground.
Agian nice plane.
Here is mine. 26lbs also
Scale top speed for a 1/5 scale would be 185 to 200 mph per this chart done by Kent Walters a few years ago. Certainly proportioning to get the "scale" speed is wrong.
