I have an old OS .46 with a davis conversion for one of my planes, I love it because its so quiet. I was wondering if anyone had ever run one in a car. I have an old T-Maxx roller and was just thinking about how much more quiet it would be... Would it work? I would probably have to rig up a cooling fan or something, it doesn't seem like my plane engine gets too hot...

The same manufacturer sells heads for car engines.

Fantastic! I havent been to the site since I ordered my other head, which was years ago. I just ordered the OS .12 head for the hell of it. Thanks.
