As anyone who has flown a Beaver will tell you, they are completely trustworthy
and, as mentioned above, aeroplanes are inherently more stable, and this particular Beaver stalled at around 30 kts - in fact we often took off across the runway if the crosswind was bad enough. We also had a full IFR fit plus Decca, so we didn't get lost
Of course, it was in the military, so things were a little different - we had good reason to go off in bad weather. Certain pilots I know were doing radar approaches in Bell 47s with that basic instrument fit. I was happier doing that in the Scout.
I don't recommend a 45 kts stalling speed in any helicopter - they don't have one. The minimum IFR speed will be in the flight manual
