Are you are looking for RWD, AWD, FWD, or industry leading drift cars? RC Atomic has options for the serious to beginning racer / drifter and everything inbetween.

BZ5

Atomic is always aiming to provide racers top level competition machine and we have been working hard after BZ3 released. After years of experience and listening to racers opinion around the world; We now fully re-design our winning belt drive 4wd chassis and introduce the new BZ5, the new industry standard for 1/28th belt drive touring chassis!

What is new in BZ5:
- All New bulkheads and motor mount
- Longer front Arms and new knuckles: Increasing stability also more mid corner steering.
- New single steering crank with servo saver and steering travel limiter.
- Ball-head type rear suspension system; wobble and slop is significantly reduced.
- Come with brass chassis with ability to add side wings (optional parts) to reduce the chance of traction roll and add stability when running in large flow high speed tracks. (aluminium chassis will be available as optional)
- New low CG rear body post system: more rear grip and act as a barrier to prevent lexan bodies catching the rear wheels when other car hitting you from behind.
- “No-Shock-Towers design” no more breaking of shock towers and further lower the center of gravity. And the shock damper angles can be adjusted by shims precisely.
- Servo mount is compatible with slim or normal size servo (8.0mm to 11.5mm thick)
- Sway bar system (with bearing support) will be available in options
- Front caster angle adjustable (with optional front bulkhead carbon plates)
- Compatible with Kyosho auto scales body (98mm wheelbase)
- Front width is 74mm with Narrow Wheels (N-8.5mm 0 offset)
- Rear width is 74mm with Wide Wheels (W-11mm 0 offset)

Tips from the Factory Team:

Take your time building the kit, AWD chassis kits are much more complex that our RWD MRZ/MRX platforms. You will find that the quality, fit, and finish is second to none, simply follow the instructions and tips from our factory drivers and you will be rewarded with and amazing performing car! There is nothing like the feel of a properly tuned AWD car in this scale!
Be sure to take you time with the servo saver assembly, it may require an extra set of hands to help with assembly. Make sure you are in an area that will allow you to find a part if you accidently drop something while assembling the saver. Be sure to add some light grease as the instruction tell you.
The steering linkage threaded rods have little nubs at the ends where the threads start, snip these little nubs off each end so when you tighten the ball cups all the way the nubs won't be able to push into the ball cups and cause binding at the ball.
On the shock bodies, be sure to check that the bleeder hole is open, I use a cheap dental pick I purchased at the grocery store to insert and open the bleeder hole. This will ensure there is no hydraulic lock with the grease in the shocks which would create binding and tweak. The key to a good setup is ensuring the shocks all moving very freely together, if you press on the front corner of the bumper the opposite rear tire should not leave the setup board or track surface. Sometimes using lighter grease in the shocks works better, some of our team drivers are using 15,000 front and rear.
Be sure to use a wide bumper like the Atomic Aluminum+Carbon wide bumper with 0 offset wheels on the front of the car, going beyond that can increase the risk of breaking a knuckle if the wheel/tire sticks outside the bumper.
Larger motors generally work better on AWD cars, don't let this discourage you if you feel you aren't ready for a very fast car. Simply reduce the throttle dual rate in your radio and when you are ready increase accordingly to achieve the speed you want. Also, no need to run boost or turbo settings on your ESC when learning to drive a modified class car, you can always add those settings later one when you're ready.
On the plastic upper arms and lower arms you may need to use a fresh xacto blade to trim some minor plastic flashing remaing from the molds away, there is also a piece of sandpaper included that can be used to clean this up as well.
If you have any questions or need help, feel free to contact any of our team drivers at their social media accounts, and please don't hesitate to approach us at the track. We take pride in being a team that focuses on helping others enjoy our brand as much as we do.

MRX

The Atomic MRX is our new 1:28 pan car series evolution which makes use of “Link-less Rear Pod” design; meaning the traditional side links are removed from the car.

The center pivot and bearing-supported rear guide rail system, inspired by RC helicopter tech is introduced, providing a bind free movement on all axis of the rear pod! This new system allows the driver to brake harder and accelerate earlier while offering greater stability and consistency when braking/accelerating and steering input overlap as the rear pod movement is independent from chassis roll.

You can feel the car drive more consistently and more predictable. Moreover, we do not have to worry about breaking side links during a race. One more benefit of the "Link-less Rear Pod" system is you do not have to worry about the battery wire interfering with the side links which often times result in the car having a tweak and not performing properly.

Other new features:

*Front Knuckle ball head position is 1.5mm pushed outward compared to MRZ SF or EX. Scrub radius is further decreased, and this will increase the corner speed and reduce the chance of traction rolls.

*Direct Drive Steering system: steering crank is removed to minimize play and slop from the system. You can feel the car steer more precise and react faster to your fingers.

*Caster angle adjustable: 0 or 2 degrees.

*New design battery mount which makes the change of batteries easier and does not need to remove the center damper anymore.

*Stock car comes with Brass chassis.

*Side wing can be added to the chassis plate to add stability (optional parts and assorted sizes of side wings will be available)

*Vertical side spring system conversion will be available as option.

*Rear Lexan body mount for touring bodies will be available too. (rear body post will not come out from side windows anymore)

*SF (simple front) and EX (double arm) suspension system will be available as option as well.

Tips from the Factory Team:

*Through extensive testing with our sample MRX cars we have found that the included Atomic S20 -1 offset wheels, as well as the optional -2 offset S20 wheels, provide the best performance for the experienced, highest performance seeking racers in 1/28th scale racing scene. The -1 and -2 offset front wheels were incorporated into the design of our new single arm front end to reduce scrub radius further than any of our MRZ line, and possibly any other chassis currently on the market. Our factory team has noted the increased corner speed and stability which is a result of the scrub reduction, resulting in faster lap times and higher consistency than we have seen in previous cars. (With this said, you can still use your current 0 offset wheels, however, this is at your own risk as you may run into servo damage if your wheels stick out beyond the sides of your body. Additionally, and you may not achieve the highest level of performance possible with this chassis.)

*Side Shocks: For best performance the side shocks will require regular maintenance, for example, removing and cleaning the shock body and piston, as well as regular intervals of grease application. In our testing we have found Atomic grease in 25,000-35,000 range, as well as Kyosho Blue in 30,000 range work great!

* We highly recommend completely glueing front and rear tires to the wheels for best performance. The Atomic S20 wheels are acetone safe so tire removal is simple, just get a jar of actentone and drop the tires/wheels into the jar and let sit for a day or so. The tires and glue residue will slide right off!

*We have found the MRX is not as sensitive to rear droop as other chassis designs and have been running as much as 1+ mm of droop on the rear of the car with great results, it feels similar to an AWD chassis on the track.

*More tips coming soon!!

MRZ-EX

MRZ-EX Front Coversion Manual

Tips from the Factory Team:

*If using 19mm wheels and low height tires we recommend removing a shim from under the front knuckles and stack it on top of the shims above the knuckles. This lowers the knuckle so you can obtain proper ride height while keeping the upper and lower arms flatter. If you are not cutting tires down and are running at 23mm or taller you can use shims as shown in the manual.

*The steering crank has been moved back on the plate to improve geometry, this will likely require you to move the steering link ball on the servo arm to the opposite side if using Atomic 1820 with plastic arm or AGF A06 with aluminum arm. We also recommend the Atomic aluminum servo saver as an option for the AGF A06 and 1820 as well, this will resolve any issue attaching the steering link.
