Never dropped a wheel, but my old Saitek Joystick. Scratched, but everything worked like it should.
Whats most damaged on my wheel is the plugs on the wheel itself. I installed a switch into the power cable so that I can power up the wheel after screwing it to the table, without the need to unplug the cable all the time. Atm I think about soldering the pedal connector directly to the wheel base, as that stupid plug keeps unplugging itself
