Thanks for the tips. We have been do the boats for a few years now and turning engines up between 17K and 25K. As far as the engines not holding up I would have to guess that the airplane engines are not the quality of those for boats because Novarossi, Picco, CMB, and MAC can all take the rpm. You should hear a Novarossi 21 hit the pipe's fourth stage. AWESOME.
I have a JETT 40 and it is great out of the box, I just thought a speed plane could turn well over 20K.
