A little more flying time and I'm now learning knife edge with it, which I had never done before. The more I fly this plane the better I like it.

The Irvine 39 has a few tanks through it and it has picked up a few hundred rpm, plus I think I was running it a little rich at first. Now it really goes straight up like an arrow on this power. I think any strong 36 is a good match. A 52 to 62 four stroke would really be sweet too.
