Chester Lanzo at the 1976 SAM Champs at Dayton, Ohio with his 1937 Radio Controlled Championship Model. Chester flew it in Free Flight. The Free Flight Director, Bill Hale, accused Chester of holding the wing tip on take off. I am not sure of the outcome. But years later at the Central Ohio Free Flight Dinner, Bill had a eight millimeter movie of Chester holding the wing tip and guiding the mode on takeoff.
Oh What Fun Model Airplane Can Be!
PS I saw Chester holding the wing tip on take off, but no one asked me for my opinion.
PSS The model was red slik with black trim.
