What did you find gents? 
Hey Dom...
I'm gonna write quickly what I remember before I fall asleep on my keyboard
Basically, the plane is just too powerful and has an imperial ton of lift.
On full throttles and with the stick pulled full back, the plane will not stall. It pitches up about 30-40 degrees, gains some altitude and loses speed, then the nose drops to level, and then it will pitch up again once it reaches 80 or so knots, and keep climbing. I've never flown in one of these before but I'm pretty sure that's not possible.
What Murray is referring to is mostly it's straight line speed. I had no problem pushing my throttle to full and leaving Murray's plane (which i'm sure was far better simmed) behind by a large margin, him doing 115 knots indicated at about 90% throttle (correct me if wrong Murray) and me doing 160, 165 indicated... groundspeed 200+.
The worst part was trying to maintain formation with Murray and E-J, cos the slightest touch in my throttle meant going from 100 IAS to 130, I kept having to forward and retard it constantly to keep at 110.
The last but not least of my problems is the plane's behaviour when under flaps. With 20 or 30 flaps (I know it doesnt need that much at landing), an increase in throttle will make it pitch down rather violently. It has a lot of lift even in slow speeds which makes it rather tricky to land, I go in to the landing with negative pitch which in every way you look at it, it's wrong. I don't know at which IAS the plane will fly on but I'm pretty sure the difference between too much lift and a stall is quite small. And then when you notice the danger of stalling, you advance the throttle, and as I said before, it pitches down on it's own.
So yeah I hope that gives you some clues on where to look, sorry for the verbosity, when I'm looking for problems I like having as much info as I can.
