I looked for one of these recently, and was not lucky enough to find one. In the end I bought a Black Horse ARF - 92" span. I fitted a Moki 180 inverted FULLY inside the cowl - rotated about 20 degrees clockwise from vertical. This only needed some holes cut in the bottom for the muffler outlets, no other curring involved. Mounted this way it does take a geared starter to get it running, but thats ok.
Flies like a DREAM , and despite having flaps fitted, it lands superbly, easy approaches, without using flaps at all.
Good luck, it will be great!
