I wouldnt go as far to say this Cap is a better fit with a gas engine. A 160 does a fine job. Mine weights in a 12 lb 3 oz, I can hover it a atad over half throttle. Now throw in a gas engine and leave the plane stock as in not going with carbon prop, spinner ,no wheel pants etc and your pushing the 14-15 lb range. You guys have to remember that this Cap has a 79 inch wing span with 1168 sq inches of wing area. I've watched Lou's videos with the 160 and the 40 cc in his Cap and you can tell that with the 160 in it that it flys better on the wing. More 3-D like. I'm sure some of you might differ, but thats what it looks like to me. I'm sure Lou will chime in and correct me if I'm wrong. I might add, that 3D is more than pulling out of a hover like a foamy. I saved my DA 50 for a true gasser plane with 1400 sq inches plus.
