JConcepts Mambos Drag racing rear tire

Mambos by JConcepts is the latest wide-body tire built specifically for RC Drag Racing. At the heart of this design is the 2.2 x 3.0” configuration but stretched out to create a larger contact patch. Forward traction is the name of the game and the goal of the larger area, in theory, gives a racer a slight advantage in the ‘hook and go’ department. One of the tricky aspects to drag racing rear tires is tire expansion and controlling this aspect of power and acceleration. The JConcepts design team thickened the entire carcass, added new inner sidewall ribbing on the inside and outside and then an industry first waffle inner weight reduction pattern. The waffle pattern accomplishes 2 things, weight reduction and provides some resistance to expansion to split some difference between a heavily restricted belted tire and a tire with no inner structure. Another exciting feature designed into the sidewall is the ability to add a beadlock style wheel such as the new Starfish wide beadlock wheel. The rear tire has an inspired look with a wide-body footprint so the driver can feel the straight-line forward stability with very light rolling resistance.

JConcepts Starfish & Coil front & rear wheels

Drag racing continues its rise in the radio control scene and the street eliminator cars are hot commodities. As racers manage to successfully tune in for more performance, they also ask for more options. JConcepts have introduced a wide range of wheels starting with the Starfish Mambo beadlock. The 3-piece design pinches and holds the Mambos tire assembly together while providing one of the most scale looks on the circuit. The drag cars turn serious RPM’s, and the tires are under tremendous centrifugal force while in acceleration. The beadlock setup is constantly under stress to hold the assembly together. The Starfish beadlock wheel is a 5 spoke option delivered in time for the most hardcore street racers wanting to run the wider rear tire option. The inner ring structure with massive ribs fit inside the tire and provides the main base of the beadlock. The inner ring will seat into the radial openings on the tire located on the inside and outside near the bead. The wheels fit a vast number of vehicles for anyone looking to undertake a Street Eliminator project and accept a 12mm hex drive. Popular vehicles which use the Starfish Mambo wheels include, the Traxxas Slash, Bandit, Rustler as well as the popular line-up of Team Associated short course trucks and now, the purpose built DR10.

JConcepts A2R 190mm TC body

The JConcepts team is back with a follow-up to their A1R touring car body, with the release of the new A2R. The new drivers body has fundamental differences necessary for performance starting straight-away in the front-end area. The shrunken front-end is considerably laid-back, shortening the nose allowing the force to be placed over the front tires. A-pillar rails extend over the hood for some air deflection straight over the nose and strengthens the front wheel well area. The front windshield is tucked back inside the rails sunk and connected to the aggressive roofline giving the A2R its distinctive shape. Behind the front wheel well and in front of the rear wheel well is a definitive edge that strengthens the openings and also provides better race posture. A hard edge runs the bottom of the rocker-panel providing more grit to the design while also providing extra front to rear rigidity.

JConcepts 1963 Ford Falcon Street Eliminator body

This new 1963 Ford Falcon from JConcepts is intended for street racing and drops to the popular Team Associated DR10 and SCT conversions as well as drag racing builds currently in the market. During the design, it was important to maintain a narrow width to match track widths of popular vehicles and to slip through the air at a high rate of speed. Also, a lower trim line on the sides and front chin-spoiler minimises draft inside the body shell. The round and beady headlights create the feel for this legendary vehicle and the bar grille separates a broad front-end. The front bumper is moulded in position along with an additional and lower trim-line for racing purposes. The hood-scoop buries into the windshield providing that racy look while the cab itself looks strong with chiseled window framing and mock trim package. The rear fender torpedoes back to create the base for rear taillights and a drop-down through the rear bumper to complete some of the futuristic styling. The side panels of the body are quite recessed and with included decals, the arrow shaped body trim can be mocked into position for a more ‘Falcon-ized’ appearance.

JConcepts 2007 Cadillac Escalade MT body

As the monster truck segment evolves, options are key and with a range of sizing, wheelbase requirements, the Escalade by JConcepts fits several trucks currently on the market, including the Losi LMT. On the design side, the dramatic grille is placed front and centre with the stunning and tall front headlights to create an impact. In the world of SUV’s there is nothing more iconic than the look and stance of the Escalade. The high-slope windshield angle cuts through the air with a tightly compressed rails on top to channel air over the large cab and rear enclosure. The SUV allows a lot of space for doors and windows but also decoration space for paint and decal schemes. Following the fenders along the door lines, the Escalade is rather slim and upright and the built-in trim on the panels creates a rather accurate and durable design. The fender flares are larger in size to accommodate the monster truck sized tires like Renegades, Firestorms, Golden Years and JCT’s. The rear gate section has body lines for a large rear window and impression area for license plate blending into a wrap-around style rear bumper. Included in each body set, a clear and heavy-duty polycarbonate body, decal sheet and the paint mask for all windows.

JConcepts 2.2″ Stadium Truck Sprinter

The Sprinter tire from JConcepts is now available in a 2.2″ Stadium truck variant. Featuring square, angled pins that are stacked vertically to flex and fold evenly across the tire the company started with a new tread and focused on durability and performance to bring a rear tire option to market that competes on loose surfaces which are wet or dusty. The outer sidewall of the tire has angled pins incorporated into the design to help release the turn and provide the rotation not only needed in dirt off-road but specifically in dirt-oval racing. The blended tread to tire body is supported with a generous radius which promotes “pin snap” and resists tearing or separation. Horizontal traction bars connect several pins near the centre of the tire which bonds a critical area for increased push at high-speed. The sidewall area blends nicely into a step-spike feature which helps smooth the transition in bumpy sections and create side-bite.

JConcepts DR10 brass optional parts

Some new brass options for the Team Associated DR10 from JConcepts with a new front suspension bracket and servo mount bracket. Setting the trim on any RC car is crucial but perhaps even more critical is for the trim to remain consistent throughout a race. JConcepts introduces the servo mount bracket for the DR10 line of vehicles. Constructed of brass to add weight this unique part offers benefits over the stock mount configuration. Most drag racers like to add weight to the front-end of the vehicles to maintain balance which allows the vehicle to stay on 4 wheels and move forward more efficiently. The mount fits snug inside the chassis servo mounting area increasing the support while the 2 screw mounting locations are beefy in design and zeroed in for a direct mount to the chassis. The bracket has locations on each side for included 3x6mm set screws to help align and maintain servo position during racing conditions, crashes and hard hits. The set screws are intended to touch-off against the servo case and provide additional support keeping the servo in the intended position which helps maintain consistent steering trim.

JConcepts announces signing of Joe Bornhorst

Completing a trio of signings for JConcepts, 1/8th off-road specialist Joe Bornhorst joins their team for 2021. A driver capable of winning at the highest level, Joe will blend in nicely with the JConcepts team while assisting with tire selection and compound advise to drivers racing in the 1/8th off-road classes and in particular on the Tekno RC vehicles. Not a new driver to the scene but a fresh champion that has recently added a ROAR National title to his credit winning the 1/8th E-truck championship in 2019. A great asset at the races, Joe will be seen at events including the Dirt Nitro Challenge but specifically during the Racetime Entertainment events where the JConcepts team is on-hand supporting the brand and all racers in attendance. Known as a driver that can wheel a 1/8th E-buggy, Joe will be able to provide valued feedback in one of the larger classes of concentration on the race schedule. Joe plans to make his JConcepts racing debut at the Southern Indoor Championships in Autaugaville, Georgia. On Joe, JConcepts’ Jason Ruona said:

There are only a handful of drivers that can muscle a 1/8th buggy, getting every bit out of the vehicle. Joe has that mystery speed everyone looks for at the races and pushes the limit of what an RC car can do on a race track. With incredible track knowledge, Joe, together with the passion of our design team, we plan to continue our push for the best performing and looking products on the market.
