AirSimulationFilter uses a lot of memory

I've seen a number of people that are hitting out of memory exceptions in the AirSimulationFilter constructor. This array could probably be shrunk.

This should be a lot better as of 749ebe9

In my local install, this was using about 2gb of memory and now it's around 100mb - though it will grow if you have more parts.
