Did mine on the R22 at Jandakot Western Australia back in 1989. Right down to the ground many times with Colin who ran West Coast Helicopters. No doors in a hot climate with your hand always on the collective. I can't say I enjoyed it but Colin is always there at the back of my mind. The Robbo is an uncomfortable little helicopter but traches you to fly just like the PA 38 fixed wing. If you want a nice aircraft never buy either.
Is Colin still around? Must be in his 70's if so.
