I got both of the parts from my local hobby shop. Thankfully a good friend works there and just converted over to the rb6, so we will be getting all the extras

A small batch of chassis came in and they were shipped out to those that had ordered them. Joe said more were on the way. I know I will be getting one before I go racing outside as I think with the extra flex in it, compared to the original chassis, will help.

Thanks for the clarification on the rear camber plate weights.

I ordered the LW blade body which im going to spray bomb one color and a low-profile servo for my car, that alone will shave roughly 32g

my futaba bls351 was 62g, savox 1251 is 44.5g so 17.5 there, and roughly 15 or more for the body as I ran a gen3 bulldog previously. Next is ti- screw kit.

Hey guys I've been working with a few guys from Norway that came down to the Reedy Race, mainly Chris Svennson. They run their cars massively different than I am used to seeing, so I took what I was trying on the rear end, and took some of the front end stuff and wow, car is planted.

Check this out, I had a buddy try it on his stock chassis car and white springs last night and he ran the best laps with his car and said it was just easier to drive but still had steering, just not that hook style steering.

If anyone tries it, I would like to hear any feedback on what you think and the style of track you are on.

Going to put the setup in tonight and race tomorrow. Will update. The only problem I have is I don't have those pistons. Can I run the 4 x 1.3 instead?
