E2021 - MBX8 1/8 Nitro Buggy Kit

Chassis:
The MBX8 chassis features a new design that improves traction and stability in bumpy conditions and on the exit of corners. The steering post are also keyed into the MBX8 chassis for easier maintenance.

Differential & drive train:
High Traction Differentials are included in the MBX8. The Mugen Seiki HTD provides increased acceleration, longer runtime, and more consistent handling. The HTD's also increase stability, traction, and improve handling in bumpy conditions. The HTD has a new larger volume diff cup to increase consistency during long main events. This makes it easier to time rhythm sections, better in bumpy and low grip conditions, helps to increase traction, and increases fuel mileage.

The new gearbox makes allows you to remove and service the differentials without detaching the suspension arm mounts. Easy access to the front and rear differential.

New straight cut 13T bevel gear & 44T conical gear. The new straight cut bevel and conical gears increase acceleration, runtime, and efficiency. A free and efficient drive train will also increase speeds while cornering.

Light weight one-piece wing mount:
The new lightweight one-piece wing mount lower the center of gravity. The position of the wing and wing mount is optimized to improve the performance of vehicle. The height of the wing mount is adjustable. This allows you to control the down force on the rear of the vehicle by simply raising or lowering the mount on the shock tower.

Light weight high down-force wing:
The new IFMAR legal wing is lightweight and provides amazing down force and cornering. The underside of the wing uses a new design to reduced weight and creates additional down-force.

Suspension:
New suspension mounts. The FF/FR/RF/RR are new for the MBX8.
The front and rear lower arms use a new impact resistant material for increased durability. The new arms are box-shaped and include arm stiffeners to reduce flex and increase durability. Adjusting the hardness of the lower suspension arms is now possible. This allows you to fine tune the steering and traction from track to track. CFRP plates will be released as an option part.

Center differential mount & plate:
The center differential mounts use a stiffer material and has a new top plate to reduce chassis flex and increases clutch bell, spur gear, and clutch bearing life. The reduced chassis flex also provides more consistent handling in all conditions. The top plate design also makes it easier to adjust the brakes and easier maintenance.

Enclosed Battery box and updated carbon fiber radio plate:
The MBX8 still uses a flat 2S Lipo or Life battery, but the receiver battery is now enclosed in a molded battery box. The battery box allows for quick and easy access to the battery. The molded box also helps protect the battery from hard impacts. The battery box is mounted to an updated carbon fiber radio plate.

Other new parts and upgrades:
Body, Clamping Servo Saver Nut, F/R Shock Towers, Front bumper, Front center and rear center universal joint.

A friend of mine raced his for the first time today. He was having problem with small chips of rock got stuck under the center diff top cover on ever heats and ruining his diff case. It seems that the center diff top cover is too close to the diff unlike 7R.

This is what he did before his main, he made a hole on top of the top cover and he said it was good after that, no more small rocks stuck in between during his main. Any of you guys have this problem? Do you know if the 7R center diff top cover can be use with the 8?

I never liked the new center diff cases after the MBX6 that's why I still run the MBX6 center diff cases they split and make getting the diffs out much easier as well. They bolt to the same holes in the chassis as the orig do. They work perfect.

Some stated reasons for moving away from split-center diff housings is their tendency to flex under load, leading to gear mesh issues, shorter clutch bearing life and less consistent braking. I suppose this could be remedied with aluminum split-supports, albeit at a slight cost and weight penalty.

It should, I can’t see them x8 center diff mount being different from the x7. If you do go that route, hotrace sells the aluminum mount. Part combined with shipping was a lot though.. I stripped my fair share of mounts over the years with the plastic pieces by over tightening

One of the biggest advantages I can see is with the bones, you can replace pins on both sides to reduce slop in the drive train. Where with the Uni, there is going to be slop in the yoke that you cant or it would be difficult to change the pin.

The bones will also have a easier spin drive train.

Yes, I run them on mine. No drilling holes line up perfectly.
