Aerosoft just got some new sound recordings for the Twin Otter, to improve the sounds. If you have real life experience with the Twin Otter, Mathijs Kok is looking for people to help test the new Twin Otter sounds:
We are building a new sound set for the Twin Otter and we would like to invite some testers. Clearly we prefer people who have experience on the model because it has a internal sound that is rather peculiar (with nearly no sound dampening and the props directly aligned the the cockpit).
We do have some pilots assisting us but it is clear we have to find a balance between what it should be and what is expected.
Contact me on [e-mail snipped, go to the Aerosoft post for the e-mail] if you like to assist us.
