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.

My 7r is 3 seasons old and I’m a rubbish driver at best. I’ve only broken 1 front arm. It was cold and it was a hell of a hard hit.

Not too much to talk about as long as we don't have any details...

I think perhaps the people that were asking 2 years ago about a successor to the MBX7R had all moved to new platforms instead of buying an MBX7R, lol.

... So I will Start, I hope it keeps the MBX7R Shocks... Nothing wrong there, and no I don't need a split diff mount.

Bleeder caps for the shocks would be nice.

Alright guys, I have permission to talk about the MBX8 now that Xray has shown the '18 XB8.

The changes are small, some of the older mugen guys will remember that there was once a version like this. The changes are small and will deceive you into thinking it's a 7 but rest assured it's evolutionary rather than revolutionary.

First and foremost are the LW aluminium drivetrain parts, like the MBX6R and yes back to CVDs. 4 shoe clutch.

Suspension wise the shock towers are lower and the shocks are shorter as the travel is more efficiently used. Bleeder caps are standard. Front lower arms are like the Truggy front arms, with hinge pin bracing. The new base setup as been developed using 1:1 top tier racing wisdom and parts were changed and bettered to have the least amount of compromises setup wise, added the much awaited up travel limiters AKA bump stops. The out of the box setup is even better and the amount of option parts you have to acquire is cut down immensely.

Steering geometry is better, bump steer is kept to a minimum and now it actually works to our benefit.

Radio tray is new, steering servo now transversely mounted and the electronics sit close to the steering servo.

Centre diff support is new, now the brake calipers are side mounted so there isn't a need for a reinforcement.

The chassis is new, with the component placement being more tidy and efficient there was a great effort to centralize mass. The engine and centre diff are moved right and back, the fuel tank slightly outwards and the electronics to the left. Front and rear overhang are kept to the minimum possible by going long wheelbase. To be included is a 30gr ballast because in certain engine/electronics/tires combo the buggy can be underweight!

The new body has smoother lines and transitions. Aerodynamics are better, mainly flow attachment and the entire body helps the car cut through the air effortlessly while helping cool what's inside.

New parts are: Body, chassis, the shock bodies and tower, wing and the one piece wing support beam, radio tray, centre diff supports and gearboxes to accommodate the larger diffs, now supporting LW internals. Speaking of the diffs, a limited slip diff option is in the works.

The setup settings are rationalized and while there's less choices they work great and the new parts don't spoil anything the old parts were good at. It was a win-win scenario. The buggy is lighter by almost 200gr. As many important parts changed (read chassis) there is no cheap way to convert a 7 to an 8.

I saw Robert testing them at the Euros in Sweden. He went back to the regular cap - not sure if because it was supposed to be tested "secretly" (it was during practice or qualis) or he just prefered the regular shock.

The car in the picture has uni’s and not a one piece wing support you speak of. Not to hard to notice bleeder hole in shock cap
