Good question Curtis ! I have heard that the older Twin Squirrels can't maintain height on one engine. Is this the case? If so do the N models have much better SE performance. By perf A , I mean, have the ability to continue flight after an engine failure at any phase of flight. Hope this clears the question up
Thanks for the icing clearance info.
Docstone, could you tell me what SPIFR means? Sorry to be slow but been out of rotary for 15 years and just getting back in.
