Wombat
Gary, I'm pretty sure that machine you have is a one-off.
I have seen a Wombat once, before the idiot owner wrote it off.
Nice machine, but not for a beginner.
I assume your machine is a two-seat derivative of same.
I had heard there was one built, or part-built.
I doubt if you can do much with it, as UK regs would make it
beyond economic sense, if it was possible at all.
Perhaps you might post a picture of it here, if convenient.
A lady by the name of Shirley Jennings might be able to supply
more info on this. I dont have contact details, but the British
Rotorcraft Assoc would have.
Cheers.
