Grease and oil attacks dirt and soon will have the opposite effect. I personally do not recommend it. If you only run indoors that may not be an issue. A faster traverse is frowned upon at most RC tank battle days but as long as it is not unreasonably fast. Use commons sense and be a gentleman and it probably will not been an issue. If you would like to reduce friction try a slick adhesive or Teflon tape on the underside of the turret to reduce friction at the contact points. Try solidifying the slipper clutch gear. I solder mine, which can be done is place and take under one minute. Some guys blue the blue gear or CA it. Soldering is free and very easy. The rotation unit is U shaped and flexes easily. Make sure the U is tight and bend it closed a bit from time to time. Some guys eve wire tire it.

Good luck Dave. Let us know how you make out. preferably before the May event so I can prepare a formidable defense from you super traverse unit.
