I race there too. Almost everyone is using proline suburbs m4 sanded down to slicks.

I will be ordering my car soon, much appreciated for the information. Thanks!

And the 1015 fits fine, but i recommend the aluminum losi 25t servo horn i linked above to go with it.

You would need the Avid top shaft for their Triad slipper to go with the B4 slipper eliminator. The Triad is a great slipper though...

I like the extra weight up front. Seems to grip better to me.

The antenna tube is now installed. The rx is on its side to allow for full range on the shorty.

Removing the presoldered wires on the r10's is very tuff. You need a super hot iron. Don't know what solder they use at the factory but my hakko at max won't do it. I have another iron that just barely gets hot enough to do it. I always try to leave the wires as long as possible in case I move it over to another ride.

Default New Scheme

Had to change my paint scheme a bit, lighten it up as my eyes are not as good as they once were... The buggy & truck are much better than the guy behind the wheel of them
