My son has a Tenacity Truggy and he purchased the aluminum upgrade kit for it. After hours of installing it last night, one problem I ran into is the aluminum chasis is narrower than the plastic one and the original servo mount and receiver were one molded plastic unit. The upgrade kit comes with a new servo mount and the instruction have you pull the receiver out of the box and just mount it to the side of the servo. This seems crazy because it puts it in direct line of fire for dirt and debris from the right front tire. Anyone have any experience with this upgrade? If so how did you handle it?
