Is there any annunciation on the CAS panel (amber annunciators should throw an MC)? When does the MC go on? Have you pressed it to turn it off? Does the EFB show anything unusual?
Is your rudder trim set correctly for takeoff?
I will say, with the more complexly simulated airplanes (which includes all of Black Square’s offerings), I never start on the runway. There’s always something that doesn’t sync up and throws random errors, or worse, I forget to config something that would have been done in a prior portion of the checklist.
