I tried it. Mine didn't work to well.
I highly reccomend buying the Mamba system elsewhere, and going with the 6800kv. The RPM and speed will still be there (these things are small enough the 5400kv will do enough) and you'll have the added torque, letting you use a bigger pinion.
As for the lipo, don't use a 4c. The 3c is plenty.
Lastly...er...lastly, paint your car bright orange so you can see it when it speeds out of vision...
