1) Would this be illegal (I do not think so, as we are only taking to motors apart to ease in a legal modification, and

2) Does anyone know if the motors are brushless or not? (i.e. will they be a nightmare to reassemble)?

While taking the motor apart to machine a longer keyway in the output shaft is not against the rules, it is probably a bad idea. I seem to remember a lengthy post from Joe Johnson when the Chiaphuas were first introduced, in whichh it was VERY strongly recommended that you do not disassemble the motors. When the armature was removed from the magnetic field and then reassembled, he found that they lost a significant amount of power (I seem to remember something on the order of 15-20%). Unless you really know what you are doing, and know how to properly use keeper bars, etc. to maintain the field stregth, then you should probably leave the motors intact.
