RE: Jett .35 RPM range (new)
Well, still no luck with the engine. To review, I'm using it on a Sig Wonder, but I'm unable to get more than 17,000 with an 8x6 APC. I installed a bubbleless tank but no difference in performance. The engine is mounted at a 45 degree angle, rather than having the muffler facing directly down. I think this may be the issue. I rotated the engine so the muffler is facing directly down and got more RPM. But I'm not interested in landing on the muffler each time (the Wonder has no landing gear).
I find it hard to believe that a 45 degree rotation would diminish performance that much, but I've tried everything else. I sent the engine back to Jett and it worked for him. So I'm apparently out of options.
So I'm looking for a new plane to put the .35 Jett onto. Any suggestions? I'd like to go fast.
