Took me a few seconds, but I finally realzied that you're talking about the Sig Bristol Scout. They classify it as a Park Flyer, so that's probably where you should put it.

10 minutes, eh? He must be able to run at a much lower current due to his choice of gearing and 12-cell setup. Admittedly, I probably don't have the most efficient prop in the world on this bird; the 12x8 is really for 3D flying. I could probably fly a 12x6 or an 11x7 on the same throttle settings and get 10 minutes. The plane's awful draggy and slow for such a high-pitch prop.

As you can probably tell, I'm really hot on finding The Budget Power System(tm) for .40-size trainers. It would bring the two "worlds" together.
