I'm posting this in case someone has or had the same issue, I've just received a Gunderson MAXI-IV pack, They look really nice. During trials, one of the first car was leaning quite a bit on its' side, like 15 to 20 degrees. I tried to push it back straight but it stayed like that so I decided to take out the bogey and inspect it. To my surprise it seems AZL bogey's pins can't be removed like the MTL ones, they are glued in place, I wish I would have known this. I broke the top pin holder. Once out, the bogey had what I thought some sprue residue, but at close inspection, I think it was a pin that acts as the coupler spring, and it was not correctly inserted into the box. So it was pushing the car on its side, hope this will help anyone that has the same leaning problem. Does anyone know if AZL has a drawing showing the disassembly of the bogeys like MTL has?
