With the growing tendency towards ever larger engines, the potential for servo & battery leads to come apart due to vibration is a constant threat. MacGregor's simple to fit Connector Locks can help to prevent this potential model destroyer. Simply pass the lead through one hole, over the centre and back down the other hole. Connect the mating half and then pull the lock back over the plugs and the job is done. (10 Per Pack).

Please check your connections regularly to make sure that the locks are still in place and that the wires are in good condition.
