I went to my first race in twenty years tonight...I repeat...I "went" to my first race tonight...I was running some practice laps at AMS in Flint,Michigan...nice clay track...I am running my rb6 mid motor...and I had really good traction,font and back...but a problem occurred with one set of jumps..a triple...its not hard to clear it but...on the fourth or fifth lap,I decided to clear the triple and the next turn without touching the ground...Ooooops! While in the air,I had a lot of time to think,I could tell by my excessive speed that I was going to clear that entire side of the track...maybe 7 or 8 hundred feet...maybe more...I knew my only hope was to slow my "air" speed down...so I started shaking the radio in my hands which in turn caused the car start cartwheeling...this of course brought the buggy to stall speed and it started to fall to the track as planned...but wouldn't you know,there were two other buggy's right in my intended landing zone...my only choice was to land sideways on one wheel...I chose to land on one of the rear wheels so as not to disturb my steering settings...I have performed this landing before...(I am a professional stunt driver)...anyways,wouldn't ya know it...the dang rear suspension holder broke...(plastic)...the pro shop at AMS had the parts to fix rm,but not for mm and I didn't have enough time before qualifying to turn everything around,I just packed up...so in closing,if you want a buggy that's easy to drive,nicely balanced,fast and smooth...the rb6 might be a good choice...too bad it can't take a little betty one point landing...

first day out with k car, had about 4 minutes of run time, then had to wait for my first qualifier. car feels solid off the bat, was having trouble when the car bottomed out on clay the metal chassis just wanted to stick causing the car to rapidly slow down. put on a chassis protector and that helped a little but still gotta get used to it. Local kid that runs for kyosho Collin helped me out with set up and showed me some tips that really helped a lot, still about a second slower lap times then my b4.2 but i cant complain with a second in the main tonight in intermediate stock. I have stock 5 hole pistons and he told me to go down to "tlr 55" pistons so we will try that and see how it goes.

I am going through my car after running the Psycho Nitro Blast a couple of weeks ago. All I will say is... Say NO to wood jumps. My front arms, front skid plate/bumper, rear arms and rear bumper/motor guard are all trashed. The front arms nearly wore through to the hinge pins on the inner pivot.
I have replaced everything but the rear arms. I just don't have any more 521 rear arms. It might be time to experiment with the RB6 rear arms...

Hey guys. I am having issues with my ball diff. When I turn the out drives in opposite directions it feels really rough. Like there is some kind of binding going on. I opened it up and all of the bearing are smooth and I rebuilt the thrust bearing. When I put it back together I was sure to use plenty of the clear grease where it needed to be. The only thing that I noticed was the rings that go between the ball gear and the out drive were a little marked up. Let me know if you guys have any suggestions.

Try and loosen up your diff case. Loosen a little at the time until all the binding is gone. It might be too tight.

Well if the rings are dented, i can see that... but if there are just some light scratches, just sand the rings a bit with some ~300 grit sand paper, and you should be fine. If it feels "gritty"... then the balls are probably too worn, and you need new diff balls. You can also flip your rings as well. I make sure to put a couple drops of clear grease in between the rings and the outdrives too. The rings aren't supposed to "move freely".. whatever that means. Some diffs (not kyoshos) even have slotted rings so they can't spin at all, and I know some people that have CA glued them to the outdrives as well (not necessary with kyosho diffs).

Never had a prob with the rb5/6 diff, prob one of the nicest I've run.
But out of interest, anyone using MIP option?

Iv looked at the option, but without knowing how much longer the outdives last, I can't figure out if the purchase is worth it. Even if the outdrives last TWICE as long as the OEMs, it is still more expensive to upgrade overall, than stick with the kyosho diffs, because the MIP outdrives are twice as expensive as the kyoshos.

Fair comment. My diff and driveshafts in the 6 is the diff from my RB5 Vega. Holding up fine. I'm not racing enough obviously lol. So still got kit 6 diff and drive shafts new from kit and unbuilt.
