I have a 17cc Chinese motor which I was thinking of using, but I don't know how well it'll run. I also have a couple Turnigy 26cc motors, the one I've run was the smoothest gasser I've ever seen and it seemed to have ample power. I don't think you can buy a gasser engine that wouldn't have more power than you'll need for the Sr. Telemaster. I'm planning on widening the fuse and putting a "radial" cowl. If I didn't plan on widening the fuse I think might go with a Evolution .60, a couple of my friends are running them and they run well.
