A value of 1724 is only about 2.6% of full range (65536), so I guess it's not that much more than you might expect. My joystick also showed values of similar magnitude when it wasn't calibrated. After calibration with jscal, the values stayed below 300 or 0.5%. -- Roy Vegard Ovesen _______________________________________________ Flightgear-users mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-users 2f585eeea02e2c79d7b1d8c4963bae2d
