Having resisted the urge to paint parts before assembly as I am used to, I made a start on the tracks but came across my first snag.
With 2 sprues worth of track pads cleaned and guide teeth (don't know if that's the correct term) stuck on they went together quickly and flex nicely especially after I noticed there was a minute amount of flash on either end of each pad that needed a light sand. The instructions say joining either side of the pads is a push fit but I had a few come apart so used a tiny amount of Tamiya white top.
However after playing with the assembled links for a while to check they flexed freely, 3 or 4 of the pins fell away from one side. I initially thought that I had over done the glue and seized the pins but on prizing the pads apart it didn't look like it as the breaks and pins looked clean. However on checking the untouched sprues there does appear to be a moulding fault running across some of the pins and in the same area on each of the sprues.
I hope the photo is just about good enough to show a fault line running across the lower section of the pins. Thankfully there are more than enough links included in the kit but I have coated the suspect pins on the sprues with extra thin which I hope may stop them breaking just in case I need them.
Going to start on the lower hull next to see if the tracks really do work and are the right length.
