Type...if I were to start again I would only go to a school that had Guimbal Cabri G2. I have flown over 30 types of helicopter (not including sub-variants) including R22 and Schweizer and the G2 is a far better piston training platform that any of the rest. When you use that to shortlist schools, then look for decent (time isnt everything) instructors, moderate sized fleet and personal recommendation. Of course if your future job is going to be on R22, R44 then use it for basic. Second choice Schweizer (so look at Bristows in USA) but G2 first.
