FSX-SE IRIS PC-9/A strange behavior under FSX:SE

[Aker 0]

I purchased the IRIS - Pro Training Series - Pilatus PC-9/A (for FSX) from JustFlight in 28/12/2017.

I did not test it under other base platforms like P3D or FSX:SP2 or Acceleration, so might be the aircraft behaves the same way,

as I expect the IRIS SIMULATIONS development has been cancelled to provide or support this product from now on.

The problem that I was facing was the following:

Any time I turn on the BAT Switch - ON - (which part is attached to RADIO Master or AVIONICS Master) I got a huge frame (FPS) hit, minus 10 or 20, if I turn it back OFF, everything goes back stable and normally. The issue appears harder when the plane turns, without using the RADIO Master BAT the plane turns as fast as the default FSX Cessna.

What can I do? If I not turn it ON and I use the GEN only then the attitude indicator will not appear.

Anyone can confirm my words?
