Inspired by some of the other excellent threads on this forum, I decided to have a go at lengthening my First Order Transporter:
I've added an extra 16 studs, twelve of them in the troop compartment: it can now take a total of twenty stormtroopers.
I have rebuilt a lot of the details:
I have also shortened the cockpit and moved it back. It is accurate in profile and still fits a minifig.
Finally, I've lengthened the engines and added some greeblies to the space between them.
Sourcing another 16 stormies was fun but expensive: Battle of Takodana + 2 batle packs + 2 Bricklink orders. Special thanks to our very own Lobot for his rapid and friendly Bricklink service.
Many thanks also to Vodnik, deskp, Veynom & Solscud007 for their inspiration.
If anyone wants to build this mod, I've created a Lego Digital Designer file: (LXF)
This file is slightly different to my "real bricks" version, due to Lego Digital Designer being a crotchety old block. Bonus fun - Spot the differences!
To build the version in the LXF, you will need a 75103 First Order Transporter and about 470 extra parts: (XLS).
Having an extra 75103 on hand (£40 on ebay with no minifigs) cuts that down to 300 parts: (XLS).
