Thanks Mr Shepherd...It was both a Houston and Dallas events where i saw the grater than 11 pound planes being alowed to compete....iYour right i think technology will eventually get it there, although i believe the real problem is the rule....which has been 5 kilos since 2 stoke .61 days.....i Fly in Europe also where i work and have run into a mess of top guys over there refusing to compete anymore unless the rules are changed. Some say any weight limits should be minimums not maximums or at least the nitros should have to be weight at full flight tanks tanks so they have to stress over ever drop like electrics must do over every watt.....
