[SkyFire]

The start of a snow cat with a dual motor drive. The larger motor is the drive one, with the smaller one controlling the steering. The drive is known as a subtractor drive, built from instructions in the Unofficial LEGO Technic Builder's Guide. The V8 is my own addition.

Snow cat with the tracks added. It needs more ground clearence.

Note to self: Be more careful where you run the snow cat. Just tried to run it over some pieces of Lego and all that happend is, it shed one track and broke a gear in one of the diffs.

The broken single-bevel 12 tooth gear, with a complete one alongside.

Latest version of the snow cat. Lengthend and raised.

[SkyFire]

Added some extra wheels near the middle, with a big increase in mobility. They have been flexibly mounted.

Done some more work on the body, starting to build up round the engine and added the exhaust stacks.
