RE: PC 9
The PC 9 is a good plane to fly as it is, these front wheels can be a problem as they are very soft. I replaced mine with a Dubro equivalent and have not had any trouble since. The plane is easy to take off and much easier to land than a tail dragger. When it comes in it sticks to the ground very well and does not bounce like a tail dragger does. I would also look a bit silly as a tail dragger because that is not the way it flies at full size.
Just be carefull with the engine, we started out with a magnum 52 fs which was ok, then went to a tt 54 fs which was a bit better and now fly with a Saito 72 fs in the nose, goes well has plenty of authority and will do all the moves.
