I remember that first flight very well: how scared I was at the time frantically attempting to negotiate this big beast around the field. The flight ended when the engine power began to sag and the forced landing was made in the rough off the runway. The cause of the power loss was abundantly clear as soon as we approached the downed Yardstick. The high revolutions caused the screws holding the cylinder to the crankcase to loosen to the point that the members were on the verge of separating. The problem could have been solved with a bigger and higher pitch propeller but as I recall I couldn't bring myself to spend thirty dollars for a propeller that may have lasted no more than a flight or two.
One day while flying the model with the large Quadra 40 Gas Engine installed, it suffered a nasty accident when it was caught in a tail wind and hung vertically by the propeller. Foolishly I immediately reduced power, instead of trying to power out of the problem and it settled heavily onto its tail feathers. In the end this was the final straw for my old Yardstick, not worth repairing and too large to store in my limited hanger space.
