Its good but I have issues, The Track assembly - The wheels took a lot of effort to install them on the bottom body. Clearances need to be adjusted. My Blade wont move smoothly and gets stuck, probably another clearance issue or the servo isnt powerful. Finally the upper body where the 6 screw holes are, these sections need to be a bit deeper and a bit more material added around them. The screws strip easily otherwise.

Almost perfect model but the area where the switch for the power mounts, need to be lowered by a bit. This area is a bit too high and hits the back cover. I UVprinted construction themed designs on my parts.
