Wayne Plamer (Workrite was his company) was the man that got us all tearing apart Black & Decker grass trimmers for winter fun. I got in maybe 3 seasons of 1/12th gas before moving to 1/8th. The Cox GTP came along at the wrong time for me and never got the support that John McKay gave the Jerobee cars, thus never took off.
Getting the Cox motor to run right was a draw back when compared to the .21 motors in the 1/8th cars. It'd be a few years later when the Lite Machine heli people showed me how a Glo Bee glo head would get the Cox motors to run right.
1/12th Gas got me started in RC racing in 1974 and I'm still at it. It's all about the fun, friends, and good times.
The Bolink starter used a 1/24th scale slot car wheel and tire.
