    Part of an Ebay lot. A 1975 Effy built by a science teacher in New York. Flew it on an A8-3 today for the first time. It SCOOTS!

    I know it's been awhile since anyone posted in this Forum, so I'm hoping someone can help me -

    Does anyone have the scanned instructions for the CMR EFFY?

    Why I'm asking is Bill Gee and I laser cut a few sets of the fins (based on an old one I had), and I'm planning on putting together some kits to give out to club members that are interested in competing, but never have before. Kind of as a "bribe" to get them started in competition.

    The CMR Effy is an excellent P/D or S/D bird. I used it in my first competition back in 1977.

    John
