How do you make it fail just after V1 or a few moments after VR? I saw in the falure section you can give a time of the engine fail. For exampe 20sec?

Its also in the failures menu, I just tried it out. Go to engines then scroll through the pages until you find V1 failure or VR failure, click to arm in say 5 seconds. Enjoy. Also it normally takes between 30 -45 seconds to get to V1 depending on thrust used and weight, altitude etc.......... Dan.
