Yes, my first diesel was an ED 1.0 cc with amber tank, around 1952 and I couldn’t believe how long it took to run out a tank. I made a little hydroplane airboat out of a cedar shingle with a razor blade rudder. It ran the whole lake and then beached itself continuing to run out the tank. I was so impressed I bought a second one for backup.

Around that time McCoy released their first version of their .049 so I quickly bought one and it had unbelievable power so I soon started flying the McCoy and used it in my favorite C/L models. They really came alive with the McCoy .049 diesel. The McCoy diesel also used my favorite 2-screw radial mounting like the Wasp, Atwood, Spitfire, Holland Hornet, OK Cub .039 & .049X, and K&B .049 Torpedo and McCoy Baby Mac glo.

A McCoy diesel with tank is very rare, most were sold without a tank. There were many broken cranks as guys over-compressed in an attempt for even more power. You had to listen for that laboring sound and then back off the compression until you heard that “Happy” sound.
