ok, from the Castle driver's ed guide:
"If you choose to direct solder or to shorten the motor wires, you may do so on the Castle Creations CM36 and Monster motors only. D O N O T C U T any part of the wire length from any other motor, regardless of brand or type. In most cases, only the last 1/4 inch or so of most motor wires is able to be soldered . If they are clipped shorter you may not be able to solder the remaining portion of the wire and the motor will not run properly, if at all. If the motor is supplied with connectors you do not want to use, simply unsolder the original motor
connectors from the wires - do not cut them off."
i do also remember reading somewhere about motor length having an importance on the 1410....going to get that manual
