Flip your arm around

Now I put the rear gold springs on and I even get close to ride height. I hope I didn't buy the wrong ones....

Never mind I think I got truck rear springs.

Edit: If I am looking at this right XGS034 are truck springs and the buggy springs are XGS013. Looks like CA was on the right track, even though these are also 73mm long just like the buggy springs. I think they just have a different wind.

diff question

It seems my RB6 spins out a little too easy when coming out of a tight corner and putting on the power. I'm running a shorty pack all the way forward - to the servo. I'm wondering if I should loosen or tighten the diff a little or move the battery back some to plant the rear end more. I don't want to give up much steering though ... Thanks

Two things... First those of you who run a bottom cover that created your own, can someone send me the ai or eps file used? [email protected] I can create designs, print, lam and cut them.
Second where can I get the blue shock collars from now?

I still use the original UM131 with my RB5, just bend it outwards a little and it will hold. Check after each run and bend with your hands. Still using the original SP2 one.

The later thicker SP holder would bend just looking at it awkwardly. Unfortunately the RB6 only comes in this thickness and you need to stock up.
