Hello again,
it is like this: when i want to fly, i press one of the three tiny grey button and i climb into the plane as usual. Then i start the engine by pressing "E" and the propeller starts moving with sound. So far there is no problem. But when the propeller reaches its highest speed, the propeller sound interrupts. The propeller keeps moving but the plane does not move at all.
In this situation i checked my gun and it worked with sound. i can fire around but cannot fly. it also possible to go back to the tower and the main menue, so my pc has not crashed.
It is crazy i know.
Is there anybody who had this problem before?
