Thanks for the information. I'll have to trade a bit of weigt in the form of batteries to use the GWS motor, but I know on 6 cells it is not pulling a lot of current.
I'll stick with rudder/elevator for this time around. Maybe a built-up wing with a bit more area if things go well.
Hey - good idea switching to a screw on spinner cap! The old style would last one landing. At least with these I can remove the cap and drill the prop and re-install without glue
