I can see both sides of the thread, which has been raised before.
The 22 ... well yes, it's difficult to master, unforgiving, etc. Been placed into the trainer role due to costs. Of course I've also heard that a 300 makes a good one, less unforgiving, etc. (And I may go up to ocean to fly one soon to try it out, heck having a "Real" cyclic for once hehe ...)
Are they really going just by cost though? If the 22 has such a rep, wouldn't it be cheaper to insure the other (300) ?
If so, and if costs are lower to run the 300, then why are operators NOT switching? (There's a thread for ya ...)
I do feel a machine needs to be balanced for it's mission.
The 22 certainly makes it easier to transition to others having more power available, etc. I flew the 22 a few times before the gov was made mandatory (That occured because too many of our brethern didn't manage to maintain RPM, having it now is nice, but not a necessity (For me anyways IMHO)).
I'd love $Shot's suggestion, I too with the 22's response would love a hydraulic pak for it
Of course such an addition would most likely leave that model single seat.
