Yeah, the tip-tank = main tank wasn't Cessnas brightest ideas, LOL. She's much nicer to fly if you fill only the aux (inboard) tanks. Dutch roll tendency and inertia is reduced a LOT in that case.Concering fps, I get much better fps with the 'free radio' version and the main GPS turned off....

Yeah I was flying the 310 in a TStorm for fun and this thing was yawing and rolling all over the place, even when I put on the A/P wing leveler (I think I must have used the virtual throw-up bag quite a few times). I found good advice to max out the realism settings in FSX for one and the handling does improve above 85kias.I have a concern that the fps issue is related to sounds. This is a very sound intensive a/c with much realism built in but I think this takes up cpu processing space thus slowing the performance. I also face issues with the RXP unit in that it draws slowly. Shez

If you spend a lot of time in the sim and go flying real world don't tell them you fly in the sim which means you really have to watch cause the instructors will know cause simmers have a habit of always looking at the instruments and that will give you away.

This hasn't been my experience. But I think it depends on the age of your instructor. I was recently flying with an CFI that was furloughed from AA who told me MSFS was how he started out. Seems like a good first question to ask a potential CFI is their attitude towards using a flight simulator. If they are hostile to it don't hire them. Find someone else who is. I find that having a CFI who understands that using a simulator is a valuable learning tool help make the learning curve that much shorter.
