RE: TT .07 props
I think I found the MA 7X3 to be the best on both the TT .07 and the Norvel .074. I usually use APCs on most of my stuff, but the MA seems to have more thrust in that particular size.

What numbers do you get with the 7x3?

I don't recall. My TT .07 isn't ina plane right now, so I can't tach it. Here's a video though.

Gaaah, you'ed think the way people talk about the TT GP-07 that is wouldn't begin to drag it off the grass anythingat all as well as that!
I have one older unused one, and was wondering how the newer ones perform and what fuel you're using?

I have used a MA 7x3 and APC 6x3 on my TT GP.07 and both worked well, didn't get any #'s on the 7x3 but i was getting 17000rpm on the APC 6x3 with 10% omega fuel and an OS A3 plug, my .07 is the purple head one, not the newer one.

I have my 07 in a Simple 400. The only prop I cared for was a MA 6x3. The 6x4 and APC 6x3 put too much load on engine and airplane performance suffered. Retired plane, not enough poop.

Mine made about 17500 rpm on a graupner 6x3 prop, in stock version.
With a turbo plug it did 18700 rpm on the same prop and 16700rpm on an APC 7x3.
Problem for me was that it was prone to overheating and a lack of longlivety. The crank to case fit is really sloppy straight out of the box and it wore out really quickly. Only got about half a season out of mine...
