I had probably a dozen Red Head Stunt 35's. I had a George Aldrich Blue Head 40, and a McCoy 29 stunt (older Style) that was all silver with no steel fins. My Dad bought it along with a all silver except for the black fins Torpedo 19 somewhere in late '51 or early '52? I never wore any of these out. I used Fox fuel most of the time. I horse traded them off eventually.

A friend had a McCoy 29 Red Head rear intake ingine. It was based more on the same cylinder assembly as the earlier all silver McCoy 29 and 36 engines. Having never worn one out, I horse traded for a 36 one time. It was a POS because someone had burned it up.

I always bought the Super Fuel in the square metal gallon cans. Being a stunt pattern guy, I always ran my engines a the 2-4 break point so they were run rather rich. They wouldn't have a whole lot of compression just after a run but seemed OK when they cooled down. They'd still run though, to start one up while it was still warm.

The McCoy 35's, OS MAX S 35's, and Fox 35 stunts were good about not running away on you. You set them right at the top of the 4 cycle point and they would stay that way. A Super Tiger G21-40 was real bad about going lean on you. My Johnson stunt Supremes were a little more prone to go lean than the McCoy's and Fox Stunt 35's. The Super Tigre G21-46's had milder timing than the G21-40 and was nicer for stunt. I had a OS H 40 stunt at one time but didn't like it as well as the 35's.

The all silver OS MAX S 35 was a wonderful engine for stunt and it ran in the air about like the McCoy. There was a older OS 35 that had black steel fins on it, I never owned one.

I still have several Fox 35's, OS MAX S 35's, a Johnson 35 Stunt Supreme, A Original style Fox 40 Stunt with the steel fins, a ST G21-40 and several G21-46's if anyone is interested? I'll give you some Ring Masters, Magicians, etc too if you'll come by the house.
