Finally ran it at the track. It tends to nose dive. But thats just something you must overcome by keeping your finger on the throttle to compensate for it.
I changed out rear screws that hold the upright rears to the bottom arms. The originals where some cheap looking philips screws.
Changed out the shock fluids from 30w to 25w. Response was sloppy and slow.
The bushings (21078) in the steering rack I changed them out to bearings.
As far as durability, I did not break a thing. Did cart wheels, nose dives and back flips and landings upside down. No screws pulled out.
I would of came in 2nd but I had wired everything to close to the on switch. And at some point the wires hit the switch and turned it off. Bummer. I moved the switch to a better location; under the ESC.
Its a great truck and lots of fun to drive.
