I'm in the midst of building the Meng Tusk kit now and have the chasis almost done. I liked the kit supplied tracks and didn't have any issues with them, other than the parts being small. It was my first workable tracks, so the novelty level was high for me. The kit supplied jig worked fine. What helped, for me at least, was applying a small amount of Tamiya thin cement in the two small holes on the pads so that the pads stayed together. I just had to make sure that the glue didn't get on the "stick" portion of the tracks so that the track was workable.
Most of my kits are Tamiya, so I'm more use to the rubber band types. It would have been nice if Meng had supplied two sets of tracks (workable and rubber band). I have a Trumpeter M1 Panther II kit and that kit comes with both types of tracks.
Overall, I like the Meng kit very much. I was very disappointed with my Dragon M1A2 SEP V2 kit. Yes, it has a lot of details, but mine came with a warped hull. I have read comments from other people who received a warped hull like I did, AFTER I purchased my kit. I used some evergreen plastic to make it as straight as possible, but it still had a bit of a wobble. I bought the Dragon kit at a LHS for about $90 and I feel ripped off (by Dragon). I'm almost finished with that model and while I am very pleased with the level of detail, the warped hull really put me off.
