Eventhough we all called the Cessna 337 a "Mixmaster" at the airport and that's the name we remember them by.....

The real name of the plane was "Skymaster" as Dar said.

The Continental IO 360 didn't have but an average 800 hr TBO (published TBO was 1500hrs) even in the front of the plane. This was at a time when other engines had a pulished 2000 hr TBO and it would seem to do more harm than good to take one down then.

The name "Mixmaster" came about from "Skymaster" due to the fact that if you ever heard one, it sounded like the engines were out of sync.

Cooling is a real problem with pusher engines in our models. A friend had a big pusher model with a Fox 78. The first time he went to fly the plane, he was making sure everything was OK and was taxing around the field when the engine quit. It melted the head button around the glow plug and the glow plug was gone.
