That may be the issue...

You know they updated some parts on the E-savage over the E-zilla? Well, essentially no one with the original E-zilla (Even Kosta who has used his to test pretty much every motor available) has broken this part. It may be that they attempted to improve the material like they thickened the driveshafts and c-hubs, but messed it up and made them weaker. This 'new' material may simply be them going back to the old style part. If I could give any advice, it would be to try and secure the old E-zilla part rather than the new E-savage part. I have just received 3 of them, i have only ever broken one from doing 12ft jumps (about 30, running 3 shocks on the front) at a lhs sponsored bash session, again, I have the old E-zilla.
