Spring RTS Engine

If I put
Set MAX_SPEED to 6500;
It makes the unit fly really fast, then Spring crashes. Regardless of where I put the line, the same behavior happens every time.
I'm not sure what else you guys would need to know. The plane is my Osprey, which is a plane that makes a strafing run pretending to be a bomber. Everything else works fine without any errors.

Soon to come : A video showing just what I'm describing above.

Edit: Gnome said it may not work with planes, could someone confirm this?

Damnit, needs moar brackets...

Plane behavior is in general: fail. For example, apply too much impulse to aircraft, and the game crashes.

Got it to work.

I'm starting to remember why I quit modding spring two months ago.
