Mugen MBX7R Eco thread!
Mugen just announced that the Mbx7R eco will be released in December! Can't wait!

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.

MBX7R ECO*Features:

- Heavy duty aluminum motor mount housing A- Heavy duty aluminum motor mount B- Lightweight conical gears- Straight cut conical and ring differential gears- Specially designed front upper and rear lower suspension arms, front hub carriers,*** rear suspension arms and hub carriers- Fully adjustable steering with new geometry, servo saver and ackerman plate- Front/Rear 16mm hard anodized threaded shocks with 3.5mm shock shafts and slim rubber*** boots- 3mm A7075 hard anodized chassis- 5mm A7075 aluminum front shock tower- 4mm A7075 aluminum rear shock tower- 5mm A7075 aluminum lower suspension mounts for optimized geometry- Stylish cab forward body- Re-designed wing mount and high-down force wing

New parts on the MBX7R ECO

-E2129 Front UprightA new designed front hub carrier that incorporates the front universal to be in a trailing axle position.* A new universal (E2218) is used with this hub and it uses an 8mm x 16mm ball bearing.-E2131 Rear UprightThe rear hub carrier has been modified to allow for use of an 8mm x 16mm ball bear which is required for the new (E2219) universal shaft. This hub carrier will also allow the use of the 15mm x 21mm ball bearing too. This hub carrier can be used for either the MBX7R or MBX7.-E2132 Front Upper ArmThe front upper suspension arm has been shorten 1.6mm. This will allow the use of the E0161 spacer between the pillar ball and the upper arm. This will allow for the same camber on each side of the buggy.-E2133 Rear Lower ArmThe suspension arm has been modified to allow for clearance so the new E2219 universal doesn’t rub the arm. This arm will work on either the MBX7R*ECO*or MBX7buggy.-E2218 Front Universal ShaftA new design universal drive shaft set for the front of the MBX7R*ECO.*The E2129 front upright must be used with these universals as they require an 8mm x 16mm ball bearing. The length of the drive shaft is 91.5mm.-E2219 Rear Universal ShaftA new design universal drive shaft set for the rear of the MBX7R*ECO. The E2131rear*upright must be used with these universals as they require an 8mm x 16mm ball bearing. The length of the drive shaft is 89.5mm.-E2314 Steering PlateThe new steering ackerman plate has 5 adjustment holes for maximum steering adjustability.-E2408 Wing StayA new wing mount that can move the wing forward maximum 10.5mm to improve traction and overall feeling of the buggy.-E2409 Stone GuardThe sides of the stone guard are changed to fit the new chassis.-E2411 ChassisThe side angle of the chassis has been changed to increase chassis strength. This will allow for a better feeling on all surfaces.-E2528 Front 16mm Shock Set-E2529 Rear 16mm Shock SetNew 16mm Front/Rear shocks which will greatly improve stability in bumps and jumps

Neobuggy posted it this morning.

Will be interesting to see how the universals hold up to electric power.

RomanCandles 11-04-2014 09:46 AM

Wow this looks really nice. Hmmmm

TheMuffinman 11-04-2014 01:43 PM

is it a kit or pre built

Bburns 11-04-2014 03:26 PM

It's a kit, placed my order through mugen when they sent me an email. Can't wait.

Pulse_ 11-04-2014 04:17 PM

glad it's a kit

what are the differences in handling compared to the 7 Eco?

Bburns 11-04-2014 06:26 PM

The biggest difference you will notice is with the 16mm shocks. It will handle the jumps and rough sections better.

egobrkr 11-04-2014 06:55 PM

The rear has different geometry as well. From what others have said about the nitro is there is more overall steering as well.

Hum man i may look into this buggy next season now from the Eco 6 . I agree the Mugens have asked for bigger bore shocks for a while that will greatly help on bumpy tracks and lower traction !

The universal axles i think they will hold up fine with electric knowing the quality of Mugens . For sure less binding and even smoother drivetrain !

It didn't take long to get this thread up!!....Gonna have my 7 on Ebay by the end of the week!!

Quite a few differences, read the entire first post thoroughly, little jumbled together but it's all there.
