Hello Harryangus, how is your Avistar wokring out for you? We had discussed it a bit in the thread about positive incidence.

As for the simulator question here, I have Realflight 4.5 myself, mostly for keeping the thumbs in shape during our long, cold, northern Canada winters. I have found the same as you have, that most of the models drop the nosea lot more than real life, and for the most part must be landed pretty quick. Even though I have been flying real R/C for over 15 years, it took a bit of getting used to. After doing some monkeying around in the "edit aircraft" section, I have managed to get a lot of my favorites to fly the way I would set up a real one of the same airplane. The biggest problem I have found is that 90% of the airplanes in realflight are "set up" overweight, and very nose heavy. This causes you to have to use a lot of trim at low speed to get the nose up, and also the nose dropping too much in turns. The other neat thing to play with is the incidence angles of the wing and stab. You can really edit a whole lot of parameters in realflight, for each individual aircraft, and therferore you can get them to fly exactly like the real ones. There is a Spacewalker in RF 4.5, but it flies more like an overpowered sport plane than a nice slow "sunday flier" that the spaewalker really is. So, I lightened it, reduced the control throws, reduced the engine size, increased the prop diameter, and put a slightly higher lifting airfoil on it. Now, it flies pretty much the same as a nice, light 1/4 scale sig spacewalker.

Give it a try, go into the "edit" settings with the avistar and you can caerfully play with settings until it flies almostjust like your real one. Do keep in mind though what da Rock mentioned, that the simulator airplane will never be quite the same. There will always be some diferences in how the airplanes fly compared to real life.
