RE: USRA Giant Scale Racing 2013
MArty, I had a brainstorm ( Or so I thought ) that I could fly my IMAC airplane in the sportsman class. Then I looked at the rules and saw that you run a 1600 ft course. Correct me if my math is off but with that size course a model would have to average 140 to 150 MPH to get close to the 2 min breakout. Even with a " speed " prop most IMACtype airplanes are in the 120 range at best.
