RE: bought a backdraft 8E!
MIne was an earthquake 8e (Jan 2011) from when I got it until July of this year.
The oversized tires, wheelies and constant unintended flip drove me up the wall. Not to mention the ballooning tires.
I converted mine to a backdraft 8e. Now it handles great, on, dirt, sand and asphault.
No more wheelies, flip overs, etc. And speed, wow this thing is fast.
