"Definitely Recommend! The build process was smooth and straightforward with a clear, easy to understand and follow instruction manual. The kit components quality is top-notch, which was what I expected from Mugen! It handles great, is super fast, and durable! Although I was anticipating supreme quality, I'm still impressed by how great this kit is. If you were on the fence and tentative, just go for it!" - Ed - AMain Employee

Refined Off-Road Performance and Design

The Mugen Seiki MBX8R ECO 1/8 Off-Road Competition Electric Buggy Kit has been developed to provide racers with the next level of off-road kit. The MBX8R ECO shares key parts and features with its nitro counterpart to improve stability, rear traction, improved jumping, and have a wide tuning range. This electric chassis gives racers the adjustments needed to dial in on any track surface.

About the MBX8R ECO


Suspension

The MBX8R ECO uses updated narrow "C" and "D" pivot blocks with pivot inserts for increased tuneability. Longer box-shaped suspension arms can be paired with optional inserts allowing for suspension arm tuning. The molded rear uprights have CFRP plates to adjust the rear roll center.

Chassis and Wing Mount

The MBX8R ECO chassis features an updated design to accommodate the updated suspension geometry. The chassis also has additional machining for increased droop and ground clearance. The included lightweight high down-force wing allows more air to flow to improve jumping. The IFMAR legal wing is durable, lightweight, and very stable on the track and in the air.

Differential and Drivetrain

High Traction Differentials (HTD) are included in the MBX8R ECO. The Mugen Seiki HTD provides increased acceleration, longer runtime, and more consistent handling. The HTDs also increase stability, traction and improve handling in bumpy conditions. The HTD differentials use 20T internal gears to improve consistency and to keep the differential super smooth. Using these makes it easier to time rhythm sections, better in bumpy and low grip conditions and help to increase traction. The MBX8R ECO comes with 13T bevel gear and 44T conical gears and 46T molded spur gear in the kit.

Top notch quality, build went fantastic. I’ve owned an Associated B3.2E, a Tekno EB48 2.1 and this is by far the best quality. Looking forward to racing this spring!

This is one of the best kits I have put together. First couple runs were pretty good after diffs broke in definitely way better. And of course tuning the suspension.
