This is one of the worst kits I have ever built. Congratulations for getting this far already. Have you yet noticed that you have to remove some plastic from behind the idler wheel to get it in line with other wheels?
Nope, I have not seen that yet. The drive sprocket & the idler wheels have such small nubs to hold them in place that a trial fit has not yet happened. I'm going to try a bit of BluTack to see if it will hold the wheels in place well enough to check alignment and get the link count right on the Fruils.
Considering how bad the fit is in so many areas I will not be amazed if the wheels do not line up.
You did get your Hotchkiss built? How does it look? I would be disappointed to spend this much time & effort and find the completed model doesn't look right . . .
