Control line stunter
By Rolland J. McDonald
While this ship was designed specifically as a "Nationals" airplane, built to operate from paved runways, the addition of slightly larger wheels should make it an excellent off-the-grass or -dirt job.
Prior to 1961 I had flown in four Nationals, and had finished second twice, third and fourth once. When I test flew the Challenger III I felt sure that '61 was going to be my year. So what happened? I broke a pushrod on the first day of practice at the Nats and left pieces of the front end all over Willow Grove NAS. Wound up flying a second-best ship to finish fourth again.
