Guys, got this from the recently concluded 2010 MSD Scale Nationals. It's a good starting point to establish our comp rules. Put in your comments/modifications please. Thanks.
Trail Class
• Description - An off-road vehicle that you would " TRAILER " to the trail head
• 140mm / 5.5" max tire size with a max rim size of 2.2"
• No wheelbase maximum- wheelbase must 'fit' truck concept/body.
• 15 Minimum Scale Points Required to compete.
• No max track width. Gates will be a minimum of 12" wide so mind your track width, measure from inside cone to inside cone.
• You must run a complete body, including bumpers, fenders, doors & tailgates. Some fender trimming is allowed but the basic shape must be retained, Fenders may be cut, or flat fendered, but it must resemble a 1:1 rig you'd see on the trail. If you remove the tailgate, you must have a complete floor and drop bed. If you want to remove your doors, you must run a full interior. "Iffy" Vehicles must be approved by the Scale Nationals Committee members.
• A shortened or lengthened body is allowable. A tubed bed must have a functional bed area capable of carrying a full-size spare laid flat (rear fender and tailgate rules do not apply to tubed beds).
• No 4 wheel steer or rear steer at all ! If you have more than 2 axles, the FRONT axles are the ONLY ones that can steer.
• No MOA axles of any kind.
• No " DIG " of any kind is allowed.
• Single engine rigs only.
• Wheelbase is limited only by your body, and must fit in your fender wells.
• Vehicle must have a frame-railed chassis. Tubed frame rails are ok.
• Vehicle battery must be mounted on the chassis. You CANNOT mount the battery ON the steering servo/axle/upper links. The goal is to place the battery where it is not visible for a more scale appearance.
" TUBERS " If you plan to run a tuber in EITHER class, here is what you need to know. It must have a full interior, 2 front seats SIDE BY SIDE, a dash, a steering wheel, a hood panel, a roof panel and a left and right side panel. If it is a jeep, it needs to resemble a jeep. The minimum size for the tubers is as follows:
Height 5 " , measured from bottom of skid pan to the roof top
Width 5 " , measured from the middle of the door bars, side to side
length, your chassis needs to be ATLEAST as long as your wheelbase, measured with the front tires pointed straight and the vehicle at rest.
NOTE: this does not apply if you have a truggy or back halfed truck with a conventional frame and cab.
