Hi 8iggles,

Knew I'd seen it somewhere, try this:
http://www.mycncuk.com/forums/showth...spindle-design

I just skim read it again and it might be just right for you given your mild loads. Based on a brushless motor intended for model aircraft, cars etc. These are all over ebay (Chinese).

Just off topic briefly, since you asked, the Avatar is my own design - called Precision3. A 1.9m span Patternship running from a 10s Lipo (36v), 2KWatt brushless motor, 100A Opto SC. 5.2kg all up weight, 2 years of design, CAD, hand cut out (pre-CNC m/c!), build, cover and fly. Maiden flight about 1 month ago. Wonderful flier with no downthrust, side thrust or incidence changes required. I'll not be at the green acres - bathroom project (but Cosford LMA is on!). OK, back to the spindle . . .
