its basically a revised , improved M1-B buggy.
While they had issues with teh M1-B and M1-B Turbo the M8 has supposed addressed all those issues.
If there is one thing i can tell you the build is awesome and the parts fit exceptionally well.
I have an priginal M1-B that broke on its first run it now is used as a basher in parking lots after i modded the rear suspension to use Casterracing ZX-1 a-arms and uprights.

Will be a while before more feedback starts popping up about teh M8 though.
