Update from Lake Arthur

I just want to start off by saying that we broke a long standing tradition today. We took the Carnivore out to Lake Arthur, and it did not rain. There was not even the slightest hint of downpour and no threat of deadly thunder.

The testing was brief, but the propulsion goup uncovered an important obstacle that will be addressed this week. At high rpm and tourque, the tming belt was slipping on the smaller pulley. We have a couple of options to prevent slipping. The first is to upgrade to a more heavy duty timing belt type. The second is to change the geometry and overall setup slightly so that the belt has better contact with the pulley. Issues with slipping were forseeable, and a solution is well within our means. We will soon have an improved propulsion system.
