Wow, talk about a performance difference. Going from the fastest turboprop to the slow Twotter must be a let down.
Is life so bad at Avantair that flying a Twotter would be so appealing? I wonder what their beef was with Avantair to do that?
Based on this comment I doubt you've flown an Otter. Since when is speed the sole basis of performance. Besides speed I would guess an Otter outperforms a Piaggio in every other aspect.
