SicNme Products 2021 Outlaw Retro Monster Truck Rules & Class Information

This class is in the spirit of the golden days of “Stage 2″ monster trucking as seen on the TNT or USHRA racing circuit of the late 80’s. This is the period where the lumbering early monsters (i.e. Stage 1) gave way to lighter, more powerful trucks with racing as the main purpose. The basis for the vehicles were modified stock pickups or heavy duty boxed frames. Some crazy designs also sprang up (tank trucks or other such oddities). Suspensions were still relatively stiff and as such it made for wild, unpredictable events. The idea is to recreate this era with R/C.

These rules were decided and voted on by the competition committee and are good for the 2021 Calendar Year.

Body: Classically styled bodies only (generally 1990 and earlier). Does not have to be replica but must be period appropriate. Allowed 1 body/name change per season.  However, a designated concrete/black top body can be run to avoid damaging particular ones, in which case this will not count towards the season name change limit.

General/Axles: All vehicles must have a minimum of 2 solid axles. Motor on Axle (MOA/Clod Buster) gearboxes are legal. Shaft driven trucks  and tank trucks are legal but due to the wide array of potential vehicles, if there is any question of legality, please ask a TK official if it “fits the spirit of the class”.

Tires: Chevron tread, fully cleated (no cut tires) Clod Buster sized or bigger. Tamiya Clod Buster, JConcepts Firestorm and Gold Year, and RC4WD B&H are all legal. Pro-Line Destroyers, Devastators and Demolishers, RC4WD Rumbles, JConcepts Renegades & JCTs, Bajas, and Losi LMT are all prohibited. Dual Tractors are legal. Treads legal on tank trucks. No shaved tires are allowed. Certain exceptions may be in made in attempt to recreate a certain vehicle at discretion of event director.  Any traction compound and/or any cleaning chemicals are not allowed to be used on tires at any time.

Wheels: Any scale appearing monster truck wheel is legal as long as it does not put truck over max width.  Any short course style wheel (i.e. Losi LMT wheel) is prohibited.

Chassis: Any chassis fitting in the spirit of the class (i.e. no tube frames) are legal. May be any material.  sicNme Products, Crawford Performance Engineering, and Grund Chassis all make legal Outlaw Retro chassis’, among others.  Please note that truck MUST meet minimum weight requirements of 9 lbs. to be legal.  Season points are tallied with a given chassis.  If chassis is changed during season, points will not transfer.

Wheelbase: No limit.

Width: 15.4″ max width on Clod Busters. This is half inch over stock 14.9″. JConcepts Tribute Wheels must be run with 11mm or 17mm adapter.

Gearing for Clod Busters: Stock 13t pinion using stock motor mount.

Gearing for Shaft Trucks or Tanks: Must be similar in speed to Clod Buster with stock 27T, closed can Axial motor.  Due to the wide variety of possible build combinations, a TK official will make the final call. Every effort will be made to accommodate a specific vehicle within reason.
