Is there a shortcut to reset the timer on a model being used. Also the space bar doesn't seem to work to turn off the engine. It just flashes really quick.
yes, you can press r for restart. These resets also the timer.
I guess you have defined a transmitter switch to the autorotation function in the functions tab in the calibrate input device window. Then these switch overrides the keyboard input. So, open the menu, change to Settings > Input Device. Press there Calibrate Input Device. Change to Functions tab and press in the Autorotation line the Reset button.
