I took out the whole clunker and removed the gear assy, I ended up breaking one the of the teeth, the little gears that are attached on each side and goes through and turns the mechanism is very wobbly, So I think there were issues already with it.. I'm going to need a spare from you.. I'll take a few if you don't mind parting with a few..
I put the clunker back in and powered the chassis up again, and still working fine and still can hear audio coming in from a channel.. First time removing one of these clunkers..
