MBX-7R ECO Spec.

1/8 Scale Electric 4WD Buggy MBX7R ECO

Mugen Seiki is proud to introduce the release of the MBX7R ECO 1/8 electric Buggy!
The MBX7R ECO is based off the World Champion MBX7 Platform with many high end improvements in steering, suspension, and many other areas to create the ultimate 1/8 electric off road buggy.

E2016 - MBX7R ECO 1/8 electric Buggy Kit (off road):

Mugen concentrated on the making the suspension on the MBX7R ECO even better with new 16mm bodied front and rear racing shocks. These bigger bore shocks will improves stability in bumps which will handle all the power that this electric buggy will produce. The 7R ECO chassis has been changed to increase strength and give the ECO buggy a better feeling on all indoor and outdoor racing surfaces.

The 7R ECO has a re-designed front hub carrier in which the position of the front axle has been changed to a trailing axle position. This new front hub carrier in conjunction with a new designed steering ackerman plate will greatly improve steering input of the 7R ECO. The front upper suspension arms have been shortened 1.6mm to allow for more camber adjustability. The front and rear drive train (diffs to wheels) have been changed and improved with new designed universal drive shafts. These drive shafts will greatly improve the feel of the ECO buggy on bumpy surfaces. The use of the universals will make the overall drive train much smoother and will spin with less friction. The new wing mounts will allow the wing to be moved closer to the shock tower and will increase rear traction and jumping abilities.

The MBX7R ECO is equipped with a specially designed battery tray which will accept either 2-2 cell LiPo batteries in a staggered mounting position for optimum weight distribution or a single 4 cell battery location...the choice is yours! A specially designed motor mount which has been beefed up so you can run bigger and fast electric motors without losing gear mesh or without the flex which causes motor or mount breakages. There is a heavy duty sliding motor mount that is anchored down with 4mm screws for extra strength.

All these new improvements on the MBX7R ECO will make the ultimate 1/8 electric buggy. The 7R ECO will be available in December 2014.
