I've searched for an answer to this but couldn't find it so here goes: I've recently gon back to flying the PMDG 737-800 in FS9. Everything works just great except the a/c taxis at about 40 kts even with the throttle closed. If I hit F1, N1 goes down to approx 25% and the a/c will stop with the throttles closed. If I even up the throttle a bit, the a/c goes back to 40 kts. I have to drag my toe brakes to hold the speed down.I remember that the NG is supposed to taxi with the throttles closed so some toe brake is required but the difference between 15 kts and 40 is substantial. Any help will be much appreciated.Thanks

Check the throttle calibration. She's normally very easy to control.

I've recalibrated the CH Yoke and CH Pedals but haven't been able to fly since I wrote the above question. I'll try tonight. We've been out of town.Thanks~

I've had the same problem recently with a Logitech force 3d pro joystick and the 737NG. Fixed the problem by deleting the joystick assigments and subsequently assigned everything again. Works OK since then.
