RE: Great Planes Reactor GP/EP 3D ARF .46-.70
P.S. - you could easily offset the 3 ounce diff between the 82 and 91/100 by a combination of Carbon gear(1.5 savings) and change up some servos or lighter battery pack - maybe 2 cell lipo and regulator.
Wood prop would save you about an ounce over an APC.
