Wa11banger,
You are right in that small gassers do not make a lot of power , but do weight a lot. Most all are chainsaw or weadeater motors and are designed for that enviroment. Weight is not a big concern. Move up in size and you get power. My Desert Aircraft 50 weight just over 3 lbs and swings a 24x8 at 6600 RPM's. That is BIG power. It will put a 18 lb. plane up unlimited with ease. The new Roto's I alluded to are converted glow engines to gas. They are light and have good power.

You are right in the smaller category. From a 1.40 to a 2.0 glow rules. It rules, but from there own up gas is king. The new Roto's and etc. are starting to make inroads into the 1.40-2.0 categories though.

My Katana took 18 oz.s of lead with a 4 cell 1400mah pack under the tank. I do have all metal gear servos in the tail though and I used the Dubro rudder mount. It has beefy hardware. You could put it on a 30% easy in fact I have it for a WildHare Edge 540T and it is 28% and is 17 lbs. with my DA 50.
