Hi Dave,

I thought about the Tower .61 is is tempting. What attracted me to the Evolution is that it had a great write up in Fly RC and claims the position of the plug prevents flame outs. The writer was Dave Geike (SP? Sorry) he seemed skeptical over the flame out claim but was very impressed. I am not sure how the Tower or Evolution engine will handle inverted. I am attempting to put together a very simple trouble free, what every that means in RC, pattern plan for practice. The manufacturer recommends an inverted 4 stroke. But I am not to sure how trouble free a inverted 4 stroke would be. Most of my 4 strokes have on board igniters. Trying to avoid that on this plane. But maybe I have no choice. I thought the 2 stroke would be a good compromise.

Thanks
Gary
