I finally put two more flight on it today. The 4S may be something to look at down the road. Right now I have no complaints about the performance. It is taking a little getting use to it. Mostly, I think, because the plane is so light. For example I did a rolling circle at about 1/3 throttle today. In a glow plane I would use 1/3 power all the way. This plane started to slow as I deflected the surfaces. The extra drag on a 3lb plane required more power. Same on a snap. The plane was pretty much stopped after the snap. Not that this is the fault of electric. I really just think it is the overall weight.
I did not run the 14" prop today. I only ran the one I cut down to 13". I will try the 14" next time out. It would be hard to beat the performance I got today but you never know.
