Latest MSFS update contain issue that was reported by several developers during beta test but still ignored by ASOBO – it broke throttle of many aircraft.
It affect JW1 and DG808 for sure, maybe Aircreation as well. I know how to fix it in the code, just will take some time to prepare updates.
– use F1-F2 keys to increase engine(s) thrust, F3-F4 to decrease
– assign Throttle Axis Engine 1/2/3/4 to your throttle lever
You will get notifications about dedicated aircraft updates soon.
