We're(USRA) starting a new race class using these...Engines can be up to 65cc, mag or battery, no tuned pipes..Our first race will be at Rabbit Dry Lake near Victorville, California on Oct 13-16..
ours will be DA60 powered if it gets done in time...Gotta be faster than our old AT6 racers, about 130 mph using the special APC race props..Could be as many at 10 of these racing..
usrainfo.org has the rules...Come on out, it will be great racing..
G62s turn 9000 in the air, I would think DLE55s would work great..
