Hi I'm having the same issue even before the recent update. I've looked into many of the bindings and can't find anything that's conflicting. On the runway and engine run-up, the engine parameters look normal, it's like there is a brake being applied only at high-power settings. Can't achieve much more than 20 knots or so. If I load the aircraft on the runway, engines already running, then the problem does not exist, and I can take off normally. But if I load the aircraft cold and dark, the problem persists on takeoff. Hopefully this data point helps with your troubleshooting. Looking forward to having this addressed, other than that brilliant airplane! BTW this is with Cargo variant, I’ll update if I can replicate the problem in the other variants.
