If you opt to get the Dragon kit, watch out for the following:
1.) There are a lot of sink marks in the individual tracks links. Some putty and sanding sill do the trick.
2.) There is a bit of a gap in the lower turret at the joint where the lower and upper turret just beneath the gun root. Puttying and filling is a must.
3.) The side rails do not properly fit at the connection point near the bustle rack (correct term?). Dry fitting is a must to see the problem.
4.) If you get the M1A1-HA version with figures. Insert the driver first before mating the lower and upper hull. It would be impossible to insert the fully assembled driver through the driver's hatch.
Besides these problems, the kit is very nice.
