Do the sanding trick, it is easy and efficient. And get the uprated clear O-ring kit, it has the same part # as the stock, just make sure it has got the clear small output axle ones before you order. The large ones are still black.[/QUOTE]

U got it backwards the small ones r black, large r clear.

u also need to use locktight on all metal to metal screws & I use nail polish on metal to plastic. Offroad loosens screws big time.
Only prts I broke:wing & mounts (I think mounts broke because screws got loose), rear hub (I think because weather was cold)
Upgrades I would get: Front & rear skid plates, wing mount (the kit one has crummy plastic stand offs, they will brake new wing mount has metal ones)
Rear chassis brace get metal one or put large washer on screw that goes into shock tower prt. or it will break.
Last is Elite or Grid mtr mount., makes messing with mtr easy. Also keeps mtr off chassis. When I took my mtr out the bottom was all bashed up from hitting the chassis.
