I don't want them to develop another MUGEN! What for, the one they have now mBx7R is great!! I have no idea what they can do to make it any better. The new Truggy is pretty much the same as the mbx7T... Let add a R to it and its different!!

ok, if you love that much the mbx7r eco, you buy 5 of them and you let us wait for the new improved mbx8 !
the mbx7r eco has its weakness and if mugen does a good job, the mbx8 will be a great car !

Has anyone tried the proline predator body for the MBX7r on the eco?

Default Springs....

So I got some mugen springs in a deal I just made. How do I go about finding out what they are? The labels are missing.

I would say anything you destroy is going to have weaknesses lol.

Adam Drake has a video on YouTube about springs. Search for Adam Drake Mugen Seiki and you should find it.

Basically, you can measure the wire thickness (either 1.4, 1.5, 1.6mm) and count the number of coils. More coils= softer, less coils= harder. The thickness of the wire has an effect on them being more progressive or linear.

so far my favourite jumper is the mbx7r eco with some easy mods ( xray arms ). i tested the eb48 which has the toughest arms by far, but the eb48 has a major fail with the main driveshaft bending. i should add a chassis stiffener....

So somehow I ended up with a 7 top arm on left side and a 7r arm on right side, I couldn't figure out why buggy pushed a lot no matter what I did. My question is, if I manually set the camber with a gauge on both sides to an equal amount (-2) wouldn't this equal out the differences between both arms??

Just picked up a used mbx7r roller. My first 1/8 buggy. On a budget so ordered the xerun sct 2250kv combo. What sort of gearing should I be starting with?

No need to swap out the arm. The 7R arms are slightly shorter to allow the removal of a shim to increase negative camber.

You will probably find that you need ZERO shims on the 7 upper arm, and ONE shim on the 7R upper arm to even out both sides. (@ -2*)

Does anyone run with weights for better F/R L/R distribution?

No, what I'm saying is I did adjust for the unequal lengths manually but buggy still was FAR from right while driving. I should of been able to equal this out with my camber gauge. I really don't know for sure that the odd arm was from a 7, maybe it's a 6 arm? The arch in the arm is a lot more pronounced than the 7r arm and after a lot of staring at it I believe the kick up or angle of the unknown arm is different . Anyone have a clue what model arm it is? I ran it for atleast a month fighting my weird unknown turning issues. I bought the buggy used and now I'm wondering if both tops were of this unknown style originally. Yes it's a 7r buggy lol

Great video! Need to show us how you built that ramp. Would like to do that for several ramps that are wide enough to use as modular features on a track....nothing that big though!

Sounds like your 7R arms are warped it happens with 7r arms one side is warped or bent more than the other due to hard crashes at least grey done break !!
