Thanks!

2 things:
1> the screws that came with the cim-sim are too long for the 550s and will cause binding. you'll need to shorten them to avoid binding (at least we had to)
2> We've found that, while very good, the Andy Mark gearboxes require that you grease them, break them in for 1/2 hour, take them apart, clean them, and then rebuild and regrease them. if you don't you'll end up with menal filings within the gearbox and that will cause more torque loss and greater gearbox heating (and possibly more noise).
