Multiplex Cortina Giant flying wing sailplane
Just a quick note to let the R/C soaring group know I have a Multiplex
Cortina flying wing sailplane listed on ebay. Type in "multiplex
cortina" in the search window, with the quote marks, and you should
get to my auction. The auction ends late Sunday night, so get in there
now and place a bid before it gets away! There is no reserve on the
auction, no fake "shill" bidders, and no games...so the high bid wins.

Update: I was at the field with her last week-end. Flew well with all moving surface acting as aileron and the inner ones as elevator. Cannot manage to have all for elevator action? (not really a need in fact).
286 mm from leading edge is the aft limit. Fly and try is the best way to get the good balancing. If you need to have down trim, put some more lead in the nose till pitch is neutral.

I had to do some digging, but I found the Cortina instructions... The recommended CG is 286mm behind the leading edge. I know it looks funny as it is almost 3/4 of the way at the root. But remember the wings have quite a bit of sweep to them.. so it works out..
Mine flies great... very stable, almost like a scale ship.. Am retrofitting a nose tow release, but since there isn't a tug available... I guess there's no hurry...

Ready to fly, after a full update.
Last flight end in a spin (some switch was activated with a bad mix (airbrakes) in place of tow release...). Nose was broken, wings badly damaged...
Nose is wider, with tow hook, glassed wings with new paint scheme.
I can't resist to show her. We expect nice weather by tomorrow, so we plan aerotowing at the local field.
