Thruster problem

i was trying to make a flying box with thrusters but something went wrong.
I had the thruster on 10000 (on a box) so when i pressed 7(HOLD) i heard the steam from the thruster go off for a second and stopped. It did not move my prop. Can anyone help me?

Gmod update broke it for everyone.

Don’t just assume something’s completely broke when it’s broken for a couple of people.

Works for me. Op, do you have any conflicting addons?

Mine fails and I got rid of all my addons.

Hmm i had that handheld bunker gun a melon friend and sandvich
