JConcepts 2022 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 slow and 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 2022 Calendar Year. All rules are subject to changes, additions and/or subtractions based on new technology, parts and/or chassis’ at any time and at Trigger King RC’s sole discretion.
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.
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, a TK official must approve it to see if it “fits the spirit of the class”.
Chevron tread, fully cleated (no cut tires) Clod Buster sized or bigger. Tamiya Clod Buster, JConcepts Firestorm, and Gold Year, and RC4WD Michelin MEGAXBIB and B&H are legal. Pro-Line Destroyers, Devastators and Demolishers, RC4WD Rumbles, JConcepts Renegades, Launch, Knob, JCT, Firestorm Racer & Firestorm Runner, Bajas, Losi LMT or any other “modern” style cut tires 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 a TK official.

Axis Freestyle RC chassis is NOT legal in Outlaw Retro. Trucks 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.

Each vehicle will be subject to a speed test at each event and will be asked to adjust settings to make that vehicle fall at or under the maximum speed allowed. Any vehicle may be subject to a random speed tests.
Vehicle cannot exceed 10 mph (miles per hour), as tested by a Trigger King RC Official on each race day, using Trigger King R/C equipment. Each vehicle will be subject to a multiple pass speed test. If a vehicle exceeds 10 mph, the driver will be required to adjust settings to bring the speed of the vehicle down and then retest. Once the acceptable speed is achieved, that vehicle’s speed is not to be adjusted during the remainder of that race day. Each vehicle may be subject to random speed tests during the course of a race day.
