A little off topic here, however I don't see the need to create a problem where none exists, and I may be dead wrong. While I like MAS for a number of projects, it is a relatively low RPM producer because it is somewhat bulky. I use them on trainers, fly some APC buzz saws, and mostly wood props which I do break a couple now and then.

The point is that an 11-7 is a lot of prop for a .46 glow engine. I hope you are not overloading it because an 11-7 is to me a small .60 prop. For a .46, an 11-6 may do well for first flights but if you want a faster fighter, I suggest a 10.5-6 or 10-7 APC (actually that is a .51 prop) after you get it tested out. Just my thoughts as I have only flown glow since Ray Arden invented the glow-plug, some 60 years ago. MAN, I do be OLD! [:-]
