RE: RC Car Actions "How to port a Nitro Engine"
Just a question on the main crankshaft, those burrs in them are done to do what exactly, balance the crankshaft ? It's sort of similar to what I did on my Hyper50 heli engine due to the crank webbing inducing extreme vibrations.
Anyone care to clarify please whats the role of the burrs in the crankshaft ?
