Another pro driver said it was the cable. So i checked it and found it had come loose. The same thing then happened to a buddy but his wire was bad. It looked fine, no damage, but with a new wire it ran fine. There is only one way to plug in the connector. Make sure you didnt force it in the wrong way. Why this happens, no idea.

In order to use the BB springs I need the traxxas collars and 22 cups correct? I know other companies make these but in general this will work?

I bought a used B4.1 WC edition. Can someone give me all the part numbers to re-do the diff. I am confused as I think it is different than a normal B4, correct?

34/72 a decent start point for 17.5 blinky?

The part numbers should be on the back pages of your instruction manual.

The T/B4.1 FT uses the same exact diff as the WC.

My manual is t4.1/b4.1 NOT WC version which I think are different part numbers.
