I've had an hour or so in the Cabri - its a really nice machine, you can chuck it around without the fear of low G etc. Start-up is also a lot quicker and safer (for the machine!) than the 22/44 - just dial in what you want and away it goes.
It also has a nice trim system which makes flying so much easier than the R22 - if you do it right you can let go of the cyclic and it'll fly straight and level. I wouldn't dream of doing that in an R22.
Can't wait for these to hit the second hand market.
My only criticism is a nasty vibration especially when coming to a hover - Bruno isn't 100% sure why, but he thinks its to do with the 3 blade M/R setup. Hopefully its an easy fix.
