I was in a group of 4 on a retractable single ! This was a disaster financially too!
I am sure this is not typical but stands as a warning!
3 of the group were great one was a complete idiot and an excuse for a pilot!
He crash landed once meaning we lost the aircraft for six months and an insurance claim! From the first crash we had no end of avionic problems which continued to cost us dearly for an aircraft the rest of the group were not even having a chance to fly!
Then he landed gear up ! Not only was our usage minimal but digging into pockets maximum but when we sold it we lost half the value!
A complete disaster ; (
So beware but as I said I am sure my example is not typical!
Sad thing he was an arrogant bast rd who blamed everything but himself
