Paul,
You must live near Akrotiri.. I'm glad Paff has inproved on the kit. The Kranz "kit" came with a single sheet 3-view with the CG marked in pencil and even this proved to be wrong.
I had to do a great deal of head scratching to get the gear and fuel tanks worked out and cut down a SM MB-339 pipe. A P-80 more than enough but it will need nose weight due to the aft location. A Wren Super Sport or a P-70 would be ideal.
