Hello, after several months of building, demolishing and rebuilding, I just finished my Lego Star Wars UCS MTT MOC.
I picked the MTT as a set to build a UCS style MOC for several reasons:
Till today there is no Lego UCS version of the MTT. The existing Lego sets (7662 and 75058) are play sets and therefore not that accurate to the 'real' Trade Federation Multi Troop Transport.
It's a challenging build, the MTT has great curves, the thing is all sloped and rounded, so a lot of trial and error fun.
I like to build to minifig scale and the MTT is just 'small' enough to do this. To realise a set in minifig scale is almost impossible for the Lego company (UCS Falcon as the exemption to the rule) When I started the build I also did not see any lego MTT MOC's on the internet in minifig scale, so I wanted to fill the gap.
When build to minifig scale the build is at a sweet spot in terms of size and weight. It's quite a large build, so you can work full on detail, but you can still pick it up easily and it still fits on a small table or deep bookshelf.
It comes in brown , so something different than the usual Star Wars grey shades. After seeing the incredible UCS Sandcrawler of Cavegod and Marshal Banana a couple of years ago, it's clear that shades of brown can be quite interesting for a lego Star Wars build.
The build is a compromise between SW universe vehicle accuracy, integrated technical functions and playability. The MTT's main function is to transport and deploy battle droids. Therefore the whole build is centered around the battle droid rack. The droid rack is deployed by a technic scissor lift that is propelled by 2 lineair actuators powered by a PF XL motor. It can also be operated manually trough the top wheel on the backside of the MTT. I wanted a droid rack with four vertical rows of droids like in the real SW universe. It can carry 48 droids (2 rows wide, 4 rows high, 6 droids in a row), so the front had to be wide enough to allow the droid rack to pass, but still small enough to take the inwards curved sides at the vehicle's narrowest point. Because of the height, there was also not a lot of room to make the bottom in the front sturdy enough.
Different shades of brown combined with dark blue grey. I tried to go for a weathered look, as in an MTT that has seen some battles. Because of a lack of greebling opportunities I made some blastholes in the sides to go with the weathered look .
Lenght: 90 studs, 70 cm/27 inches
height: 35 studs, 34 cm/13 inches
weight: almost 8 kg/17lbs
The inside is all technic bricks and liftarms. You can easily lift the set up on the 2 sides, flex is ok. It rolls on 6 wheels, so kids can move it to play with
Work in progress:
trial and error to get it moving again on 2 or more lego XL motors or skip the motorized propulsion overall. When I finished building the technic frame, it could be driven by 1 PF XL motor and steered by 1 medium motor. Now with the exterior finished the 8 kg is definitly too much for one XL motor. If anyone has some experience building heavy moving lego or technic vehicles, I'm open to tips Question to the community: would adding one extra XL motor be enough to propel 8 kg? I believe the Sandcrawler MOC is double this weight and it runs (more like crawls) on 4 XL motors?
making building instructions: I'm doing this in bricklink studio. I'm making progress, but It will still take a couple of months to finish them.
As for a total number of pieces used, I can't say right now, I'll be able to add the number when the instructions are finished.
