Coy Lady" for building project?#0 source
I would like to build a straightforward, upright-engine full-fuselage flapped stunter this winter. I have been circling around the available designs, and keep coming back to this one. So, a couple of questions for the jury: (1) any particular quirks about the airplane? It looks quite straightforward, in a photo anyway. I think someone won Oz's nationals last year with one powered by a Fox .35. This brings up my second question, what to power the little beast with? A photo I found in a current English magazine shows one that travelled from Canada for flying last summer, powered by a OS .46 LA engine, which seems a bit much on the face of it. I have my original Fox .35 from kid days in 1962, a nice new 50th Anniversary Fox .35, and my Enya .29 or Enya .35. All of which will need running-in in varying amounts. Thanks to all.

Yes, Mark Batty won F2B at the 2000 Australian Nats with a Fox 35-powered Coy Lady. The engine has a hemi head and stuffer backplate. I agree that a 46LA seems a bit big. In fact, a good number of people are using OS, Magnum and Thunder Tiger 25s where a Fox 35 once went.

The design was first published in 1959 so you should be able to trim a bit of weight from the model by using modern building techniques and use your favourite among your 35s.

Go for it. Geoff

I recently got the plans for Coy Lady & Coy Kat from Xlist plans service.

The Coy Kat is from 2 years later than the Lady and has a swept forward T/E and looks to be a bit more developed than the lady.

I also remember that a semi-scale version of the basic wing and tail setup with 'jap fighter' looks existed with a radial cowl, unfortunately Xlist plans tell me the drawing for this was not passed over to them!

The Lady shows a McCoy 35 and the Kat a Merco (I think judging by the outline).

The semi scale jap fighter version was called 'Geisha Girl'

According to Dave Day's excellent site Ray Brown won the 1960's Gold Trophy at the UK Nats with a McCoy 35 powered Coy Kat and is still active in R/C helicopters!
