I run the MP9 TKI3 kit and think its a fantastic bit of kit. Feels a bit heavier and wider than some buggies out there, more like a D8 12, but it really is planted.
My lap times started dropping when I switched from the Losi to this.
It strangely feels slower though, but handles so much easier.
Also, if you break any parts, which seem to be a struggle to do (I have only broken 1 front arm so far) then you can always upgrade to the hop up parts
