I built a Roaring 20 from the Top Flite kit in the early 70's. It was powered with a Pee Wee .02. The radio was a Mattel pulse unit with an Adams Baby actuator for rudder only bang bang.

Cox was not known for the greatest quality control back then and a lot of poor performing engines like mine hit the market. Leisure Dynamics was in charge back then.

Anywho, I decided that morning to R.O.G. my model. It was a warm humid day and the engine just didn't want to run right. Undaunted I set the 20 in the center of the runway and let go. Just about the time it got going fast enough to lift the tail, the engine sagged. This happened a time or two, then it hit a pebble. The prop hit the ground, the engine burped and began running backwards!

The tail wheel planted itself firmly on the ground and that cranky old engine roared into life! Arrow straight down the center line, right back past the pits backwards with 6 foot tall me in hot pursuit! I never heard so much laughter! My Roaring 20 lacked a steerable tail wheel and the rudder didn't do any good being in the front! Red faced I finally caught up with it when it ran out of gas. No damage, except to my ego and the model lived to fly many more times!

They just don't make 'em like that anymore!
