SicNme Products 2020 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 2020 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. JConcepts Firestorm and Gold Years tires and RC4WD B&H are legal. Pro-Line Destroyers & Devastators, RC4WD Rumbles, JConcepts Renegades & JCTs, Bajas 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.

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.
