How does the ST 75 work in
I was thinking of getting your ST G-75 Ring w/Muffler to put in my TF GE Corsair 60 size. I was wondering how your engine reacts with being mounted not in a vertical condition? What 3 blade prop would you recomend?

RE: How does the ST 75 work in
The SuperTigre G-75 should work out well in your Corsair. Just make sure it's well broken-in before you put it into the Corsair. You may want to fly it for a few gallons' worth of fuel in a sport model first, to get it well run-in. Once it's broken in and set correctly, it will run well in almost any mounting attitude.
For a 3-blade prop, maybe an 11 x 8 would work. It's hard to say. We normally run a 12 x 7 or 8 2-blade prop on this engine, so the 11 x 8 3-blader may work. Please remember, though, that 2-blade props actually work better, and you can't tell what's being used when the engine's running. If you want the "looks", then make a scale prop for display purposes.

I have an ST-G75 mounted sideways in a SIG 4*60, fitted with a Bisson Custom Mufflers Pitts-style muffler. It definitely needed a long run-in and the first several runs had to be sloppy-rich but once it got broken in on the test stand it has been a great engine. Easy to start, lots of power. I was using a 13 x 6 APC prop on it last season, but I may switch back to a 12x7 or 12x8 this season.

I have a ST 75 in the Hangar 9 corsair ARF, pitts muffler 45 degree mounting, works awsome, runs forever, bulletproof, even after several pilot error pile ins, it still has never dead sticked on me.
