The non-Helionix T3 are still stuck with a 90kt limit on the IAS UM mode IFR so I think the problem is on both variants. Limitation cannot be removed unless tall fin is fitted. To be honest the place you actually notice the lack of fin area is that it is less stable in yaw in the hover. Sure you use less extremes of pedal cross wind (ie you don’t get as near to full travel) but you have to work harder to hold a heading.
All of nips and tucks on T3 are about making it better for high altitude out of wind hover. I prefer a P or T2+ For sea level to and fro work (although I do like Helionix a lot).
