But at the higher classes, and at the NATS, your plane must be below the limit to be legal. If someone from the AMA or the NSRCA would care to explain the reasoning behind the 11lb weight limit, I would like to hear the answer. It seems to me that with modern electric components, you have about 6lbs of airframe including wheels prop/spinner, and about 5lbs for motor/ESC/Servos/Battery/Etc..... If your plane is heavy it will not perform the same as a lighter plane, but why make the bar so low and restrictive? is it just to drive up the cost? Why on earth would you drive the cost up for everyone? Does not make any sense to me.....
