Ramm, prop on landing issues are generally associated with too much pitch. Even though the engine is at idle, the prop still creates thrust. So a lower pitch is going to give you more of a "braking" action. This especially shows up when you are flying an airplane that is very clean aerodynamically, which the D9 is. Hence the need to use flap properly. More pitch will give more thrust than less, if the rpms at idle are the same. THis will hold true at idle, in the air as well. An extreme example of this is in pylon racing. Trying to land one of those at idle is very tough, so we just deadsticked them in, so we could get a good approach and get them to stop.

There was a lot of discussion earlier in this thread about some having problems not having any luck landing this plane. The times I witnessed such issues, the plane was not slow enough, and a high pitched prop was being used.
