Dak, in the days of the military Gazelle we used to low fly at IPS or MPS to give 120 kts or 135-140. At those high pitch settings, the risk of jackstall in a bird avoidance manoeuvre was real. We also demoed the dive to VNE and recovery (including jackstall if you were harsh in the manoeuvre).
Nowadays the DHFS Squirrel is artificially torque limited and so high pitch settings at low level are uncommon and the dive to VNE is seen as unneccessary. I suspect that if the Squirrel was actually owned by the military and used on the front line as the Gaz used to be, then you proably would demo the limits of its flight envelope but because it is owned by a civilian company and operated in a training environment to their limits, you don't.
That doesn't mean that the Squirrel won't jackstall (or suffer servo transparency if you prefer that term) - the only way to find out is to calculate the VNE (if it has a graph for it) and then dive at max pitch/Torque and pull - if it doesn't do it then great - write and tell us.
