I can only imagine the motors that will go in these axles.

It's been three years since I had a berg! I'm building a set of Puller 400 based motors for it. All black and gunmetal grey parts. A prototype compound curve magnet shape is getting made right now, FEMM results show a decrease in terminal resistance along with smoother starts. It will be a great platform to wring out protos! |

Very nice, they look just like the links I need  I didn't think it was possible to run OG 300's with 8* VP parts, if it is I would love to know how. |

Awesome, well the axles I have had AX10 C's and VP Knuckles so I should be golden. I have a lot to learn about these things called Bergs, just as well I am in the good hands of RCC. Thanks Big Ted.  Last edited by Highlucks; 01-29-2014 at 08:44 PM. |

It's 3/16" diameter from McMaster. I run a 10-32 die over it, then drill and tap Revo rod ends to match.

Looks good jack. Better build this thing strong. When I first met John he was running a fire breathing 6s dragon. He would power it through the deepest darkest cracks he could find. Shot sparks out of the end bell for at least 8" lol

You need the Axial stubs, then you can buy the VP 8* C's and knuckles for an SCX10. The only mod you have to do is bore the C's to 14mm.   | |

Made some progress over the weekend. Put some shocks on to check the stance. Looking good I think!  |
