Hi Elson-

I am about to brake this engine in, which is already installed in a GP 120 Super stearman (ARF). Question:
Could I just burn 2-3 20 oz. fuel tanks and then fly it, or should I take it onto a stand?
And what kind of prop would you use to brake it in and which one to fly, I know now for your previous post that a 18X10 for sport f. will do it, but what brand?

Many thanks.

Enrique.
