IMO the epic fail was the mini revo. the car was to small and light and way to short of suspension to run it off road. the mini revo is basically a track or street only car. the Mini summit on the other hand should have corrected most of the things that were wrong with the mini revo. long travel suspension bigger softer tires. at least it should be usable off road. In reality if you look at the chassis it is simply to small to add a bunch of extra components for locking diffs and 2 speed trans and servos. Maybe their biggest mistake was naming things mini-****. then people wouldnt have as high of expectations for the stuff. lolyeah EPIC FAIL on traxxas part. It needed to have gotten the 2 speed transmission and locking diffs, to really make it a mini summit.
