IDK that, running it tommorrow. I have the stock body just incase but I dont run on 1/8 scale tracks with large jumps either. :P

I wonder if we all make enough noise maybe J Rouna can start extending the RB6 bodies so they'll cover like this.

I wish they would and add the little design updates. I have a new unpainted rb6 finisher body sitting here and I dont even want to paint it. ;p

The jconcepts c4.2 finnisher body has less chassis gap and fits tighter in the rear section. i have tried a couple on my mid rb6 to be sure, but i have always felt that on the rb6 ( on high bite indoor clay) had less steering and less traction with the r6b specific finnisher body. The stock blade body was in the middle and the proline phantom body had a crazy amount of steering and traction. but thats just my experience. the next body im getting to try is the proline gen3 bulldog.

The stock blade body is hard to beat. Do you have any pics of the Centro body on your car, mainly an underneath view?

not right now but i can later this week when i can get to one. there is a slight gap up front where the rb6 side pods angle into the center of the chassis and the body stays a little wider. i haven't got to run the car with the centro body but i will try to get my friend to let me borrow his for a heat or two.

Liking the Phantom body myself. Look into using the shark fin that comes with it. It'll help stiffen up the rear of the body a lot and help keep it from cracking.

Thanks Teufel Racing,

I first used the Phantom in EUROS warm up when I went with MM on a low traction clay track. The body made a great difference to the performance of the car...more steering but not too much and felt smoother more easier to drive

Tried Zack's setup indoors on turf yesterday and it was my first time indoors. It was great. I tried many different used tires left from the summer. Holeshots and handlebars rear seemed fine, rebar front. I also used the soft sway bar. Anyone noticed it's a bit too long? I cut it on both ends a bit. Mistake? Well anyways the car felt really nice. Had only stock springs so I gonna do that change yet. I had a new Tekin gen 2 8.5 conbo as well but had terrible cog issues. Tried everything, no relief. The motor worked well with my Orion r10 pro (own two rb6 cars). I guess I need to send it back to Amain for a change. Radio is a new MT-4S.

So does the buggy come with the Aluminum steering rack now? Or does it need to be purchased separately?
