Hey Foghead,

I have the MRC Super Brain also. I would personnaly charge the pack at 1.0 ma. I suppose some would say go easy on the pack and charge at 0.5 ma, but I don't think 1.0 will do any damage. (2C would be 0.8 which you can't set with the MRC)

Make sure you set the charger to 1.0 ma, it defaults to 3.5!

That 6 cell pack may not give enough performance - but give it a try. I'm using 8 cell Nimh packs and really like them. I'm assuming you have the GWS 300 motor.
