P3Dv3. Go firing up the latest version of Manfred's popular Douglas C-47 Skytrain the moment you install it without ensuring your ducks are in a row. This is by no means a typical freeware "toy" and if you treat her wrong she will respond accordingly. This is honestly one of the best if not the best freeware aircraft I have ever touched. Dare I say A2A quality? It's pretty damn close... Well the results of my first flight can be easily seen above. Failure on 2, fire on 1. No doubt it was a "white knuckle" approach. Highly recommended!
