adding propwash, and other dynamics

Hi all, I'm trying to modify some cfg's and air files of airplanes I've really flown to make them a bit more real, as I remember them at last.. :)So far, I was able to add a propwash effect by moving the engine location below 0, and moving it to the right to have some torque to counteract. Then, I also moved the empty weight CG forward, to gain a little nose down attitude when cutting power and on stalls. But I'm not satisfied yet. The plane is way too stable on its lateral axis, it seems that engine or not engine, the pitch is unaffected by it. The torque is very very low, I remember I had to use almost full rudder on take off with 300 HP. And landing is a trick, it floats too much, I can almost land with the trim and not the elevator...So, to summarise, here are the key elements I need:- increase torque, P-effect, etc, everything related to the spinning propeller, say- modify the pitch momentum when changing RPM's, or configuration, stalls.. (propwash, flaps, etc)Thank you very muchCheersP.S. FSX, I forgot to mention :)
