ever since the levers and switches came out i wanted parring breaks, so i can activate the engines yet have the plane sit still, i have activated a braking lever, but as soon as i let go of it it turns off the brakes, but i need it to stay on breaks. how do you do this? the break levers work while engines are on, but they dont lock.
Button with a variable
Piston on the ground
Look at this for ideas
