Need help with my G3-build

[JoFreak]

Went out driving today, after I replaced those stupid tower hobbies drive cup springs, which are an epic fail, with fuel tubes...
What can I say? This thing is an absolute blast!!!
Bit uncontrollable on gravel. Give it the beans and I starts spinning in tiny little circles despite the centerdiff.
Even managed half a backflip...
On gravel...
Uphill...
With a center diff

Handles like a dream, maybe a little more initial tension on the back springs.
Definetely need thread lock on the wheel nuts though.
As for the Bigmaxximum, it pulls away absolutely smooth, no cogging at all

Really looking forward to drive this truck on a track!
As for a video, I'll see what I can do, have no camera my self, but IIRC a friend of mine should have one.
