I have one also and agree it is a blast to drive! I still need to paint the shell, but keep on getting it dirty playing with it.
It's the first RC I've had in a long long time, but my old roommate got me back into the hobby last year and I kind of went crazy with the upgrades, lol. He has a nice modded Traxxus Stampede and it's a beast with the brushless motor and what not.
So for mine, I've upgraded the drivetrain with
FastEddy Sealed Bearings, stronger steel
Tamiya universal joints, and locked
front/rear differentials 4x4 RC Shop (the inserts work great, can be removed easily to convert back to an open diff, and made in the Czech Republic, I think originally for the CC-01 series). I bent my stock universal joint / drive shaft after a few hard collision with a tree stump. But overall it's been super durable bit of kit.
The rest of the upgrades were more for bling (I'm a sucker for anodized aluminum) and some performance. The suspension is mainly an anodized blue aluminum long arm kit from
Yeah Racing and the Tamiya
aluminum oil damper kit. My baby also has
Tamiya Aluminum Servo Guard ,
GPM Servo Saver Arm,
GPM steel turn buckles,
GPM aluminum front bumper, and the
Yeah Racing aluminum wheelie bar with oil dampers
I sourced my parts from Towerhobbies.com, amazon.com, ebay.com, rcmart.com.
So besides painting the body, I would like to add the driver done up as the Stig (need help sourcing a blue mirror film for the visor), working headlights, turn signals, brake lights, etc... Tamiya has the TLU-01 / TLU-02 controllers that handle this. Also would like to upgrade to a 15.5T brushless motor, as the stock ESC actually can control both brushed and brushless motors. But my 100 series and vet bill have been eating into my hobby funds as of late so these will be on hold.
