How Do i put a detacher on a plane

@ThePilotDude oh took me hours to understand that because I'm newbie there but thanks to your help!

It's a bit more complicated than that. 1st assuming the car has controls that overlap the airplane's controls, you're going to have to set the airplane's engines to some unused AG, so when you want to drive the car, the plane won't go anywhere. Next you'll have to make the car a subassembly by removing the main cockpit. Stick a detacher set to an unused AG to the bottom of the car, and save as a subassembly. Load in the original plane, drag the car subassembly onto the screen, and use the connection editor to connect only the bottom of the detacher to the plane. Then, selecting "connected parts" in the nudge menu, nudge the detacher (bringing the car along with it) into the plane. Once in place nudge the detacher away from the car (after selecting "selected part" in the nudge menu) so it doesn't get in the way when you're trying to drive off the plane.

Save the car as a subassembly then profit
