If you watch your throttle a Mej 30x13 is one of the best. Assuming it doesn't delam.
Hey there.... Tom did say in his first post that he wanted to use a 3 blade prop. Maybe you missed that?
I tried the 30x13 Mejzlik 2 weeks ago & it was a noisy prop for IMAC. Even with throttle management you will have trouble with sound. The 29x12N is the best I have found up to now.
Look on the Hall sensor pick-up. Is it turned all the way to the left (retarded)? There were updates to head bolts & other internal areas that are significant. Give Tony a call at Desert Aircraft & let him tell you if your engine has the updates. I am sure they would have it on file.
