The high pitches keep the noise down. on the 91 fz i ran a 14-10 and on the 110 i ran a 15-10. both engines were spinning around 9000 rpm. Normally i run Bolly Wheel pants. Expensive but they last. I don't know if you want to try flying pattern. But there are three contests this year not to far from you. one of them is at the radio control club of detroit. ww.rccd.org Another one is at the Midwest field. At 5 mile and beck in northville. And another one is at the signal seekers in westland. The swallow makes a nice pattern plane i used one in intermediate for two years.
