I've struggled i little bit, but finally found what was the problem. There is small bug with the hover engines.
When i first tried them i overlooked the STOWED option, and instead i rotated the engine manually to desired position. On the runway however, i could start the engine in any mode and adjust the power, but i could not steer in any direction. Only after i unchecked stowed in hangar i could finally use steering and move the craft properly. But it was quite tricky to realise since engines were actually functioning.
I think that stowed engines should not be able to start , or should auto unfold on launch/stage, or at least have that indicator light red when stowed. It took me almost an hour to figure out why i can lift the craft but not steer after, only hoovering in place.
Another thing i noticed - hoover engines tend to tilt right or left once they reach full speed and acceleration button is still pressed.
PS:
How about spider legs?
