Help
I Ran 3 litres through my new G90 with a 14x8 MA on stand with 8oz tank last weekend . It should have been a 13x6 . no throttle or leaning at 9000 k should I start again with 13x6 and 12 grand rpm. No over heating what so ever. possibly be OK as is
Thanx Bob.

While the SuperTigre G-90 should be run at higher RPM, if it's running well for you, and flying your model the way you like, there's nothing wrong with running it slower. It does, though, "prefer" to run in the 11,000's, where you'll get the best handling and power. More noise, too.

Thank you.
This motor is brand new and I foo pard with the prop size.
It will be put in a 7ft Cessna so will run the 13x6
Should I run it in with that 13x6 some more, before installing.

Run it a bit with the 13 x 6 to make sure the engine's tuned and running well. You will have to reset the carburetor to account for the difference in RPM the engine will run.

I know were your coming form
Thanx.
