Byron original sukhoi
Greetings!!!
I had built a Byron Original Sukhoi in the early 90s with the 4.2 with purr-power systam. RTF weight is over 23 pounds and at 7000 feet here in Santa Fe NM, it just did not perform that well. The newer 50cc engines are just too light for CG reasons. Is there anyone out there still flying B.O. Sukhoi? Any help will be great!!!! The 4.2 with purr-power weighs 6/12 pounds. The way I see it will be to buy a bigger engine close to that weight.
