Lubricated everything and nothing was helping. I decided to take the whole thing apart again to really analyze what was wrong with this one.
When I first got this game, one of the hat trick targets had been clipped, ostensibly to try and remedy the lion target that was flying out of its track (the jnsert was just hella warped). I noticed that when I removed the left track for the rhino plastic, it worked perfectly, so this got me thinking. I reinstalled the track and noticed that due to the long pivot point of the Rhino coil arm attachment, the plastic was getting caught on the lower half of the longer track plastic.
Light bulb! Swapped the already clipped track from the lion plastic with the full one with the rhino. Works perfectly now.
The shorter (clipped?) long track looks visibly modified, so potentially somebody has already fixed this before and then reinstalled the tracks wrong? I can’t say.
What I can say is that my R&B is finally working 100% and I’m happy to finally send it off to a new home. Renting this one out to a buddy of mine who has some young ones he’s trying to get into the hobby. Seems like a good fit.
