Brian,

Balsa Products is a good vendor to deal with, and they carry the full GWS lineup. Here's a direct [link=http://www.balsapr.com/catalog/motors/EPS350cView.asp?ProductId=T433964]LINK[/link] to the product I was referring to in my last post. The page will show a 5.33:1 gearbox and motor, as well as a chart showing power consumption and thrust on various voltages. There are some recommended props at the bottom also; the 8x6 slowflyer, 9x5 direct drive, and 9x7 slowflyer are the best on this motor in my experience. The 9x7 will yield the most thrust and pitchspeed, but it will require the most current, so the 9x5 is probably a good compromise. Other vendors for GWS include Tower Hobbies, Aeromicro, and GWS-Parts. A google search of any of those names should get you to their websites.
