Gijs already confessed that he changed the model-hz to 30Hz.  The gear model 
code just isn't robust enough to take a large transient at that low a 
frequency.  When flightgear starts, it places the aircraft above the scenery 
and lets it drop.  At the normal model-hz (120Hz) the gear model does a good 
job of absorbing this impact, but as the frequency drops quantization errors 
cause the gear model to misbehave.
