Biggest Bushless system for a Clod

[oxide80]

Just wondering what that biggest/fastest brushless system that people have tried in their Clods'. I'm quite happy with my Castle 5700's on 7.4v Lipo, and it has more than enough power for what I need, just would like to know how fast people have pushed their trucks.

I bought my brushless Clod used long ago, upon receiving it it had Hacker ESCs and 5271kv motors with 20 tooth pinons (he drimeled the gearbox interior to make room for them). The prior owner claimed a speed of 50mph with 11.1v (or maybe it was 12v Ni-MH). I never did run it with the big pinons because 3s lipo with that kv of a motor on stock gearing is silly enough (to the point that something breaks almost every run).
