We had an original L, with the C-20 and water methanol. It worked really well, we acknowledged its limits and got 12,000 hours out of it, before a new owner put a junior pilot into it and he flew the new owner into a low cloud and came out vertical. Splat.
The 206L flew faster than its shedmate the 206B, was far smoother with the Nodamatic suspension, and for the same operating costs, we got 2 more bums on the tourist seats.
