Guys,

Downsizing the prop will most definitely affect the plane's performance, which is why you need to be careful. Go too small, and you won't be happy. Use "baby steps." Diameter has more effect on the current draw than pitch, so you can drop from a 10x3.8 to a 9x4.7, for example, and end up with a lower current draw.

tylerman, the problem with the way it's set up now is that you're exceeding the rated limits on pretty much everything in the plane when you go full throttle. Get a little heavy-handed, and it's going to cost you some $$$.

How is the plane's performance now? If you're flying mostly in the bottom half of the throttle travel, you can afford to lose a little power on the top end.
