Candid - I am assuming that what you are reporting as far as not having to add much power to get the plane rolling is an artifact of the turbine engine modeling that they are working to correct. Hopefully when 1.5.2 is released you will see better modeling of the engines and, as a result, power settings.
As Cameron mentioned, and I think he is correct, most every bug has been found and reported in the Saab 340A support topic found here. Just search on my name and you'll see a couple I am sure!
