I didn't want to bother you with this Pete so i waited as long as i could . i have version 5.152 . I've never had a problem with throttles in any of my aircraft, including Pmdg , the general aircraft like Carenado ,you name it there all ok but i hit a snag here .I'm running P3d version 4 , I have the Controls --DISABLED in P3d setting, the rudders, the yoke, and brakes, was no problem setting up but i just can't get the throttles to respond no how . In the aircraft they DON"T move , I have the Precision flight control quadrant i have the 2 engine one . I've read post after post about lots having the same problem, and yes it's the serial port one and never had a problem with it . This aircraft has been out for about 4 - 5 yrs and pmdg quality and very realistic like every thing else they put out. What they are suggesting is setting one throttle that control every thing but don't know if I'm reading the instructions wrong but I'm not having any luck .. I go to Axis Assignment bring up Throttle Send direct to FSUIPC then i move the one throttle up and down then i go to Joystick Calibration on page 1 where is says Throttle but using PFC and i tick Map to 4 throttles but nothing works then i go to the ini file in modules i delete it and start over but no luck and I'm using F2 and F3 in the mean time .. It sure been a long time since we were in Seattle ha ----Louis ---Canada
