AT THE REEDY RACE - from what I can tell when I was watching Tebo and Hara run yesterday, Tebo car much more stable than Hara and I was sitting right on the straight away inspecting both buggies very carefully through the heat. The slipper pads Hara were running were kind of "cooper color". He did say to me they are an upgrade and not part of the AVID kit. Hope this helps, I am all new to the buggy scene.

I did notice my Avid spur and Robinson aluminum pinion starting to make noise.. so i have a new spur here soaking in a cup of water overnight before i install(recommendation from Avid to make the gear quieter). We'll see how well that works.
i had same issues i soaked them in a sealed Ziploc bag for three days and my car has been whisper quite .


i got to race my car with the new sideways short pack modification. just when i thought it could not get any better . i was wrong it is way better with some changes i made if anyone is interested pm me .

Do any if you guys run saddles with the rear motor config? Seems like it would work similar to the shorty?

I never heard about soaking the spur gear in water ... might have to try it, although my stuff is pretty smooth and quite as it is.

So there are upgrade avid slipper pads?? I just looked on Avid's website and didn't see any "upgraded" drive pads or slipper pads ....

Anyone has a setup that gives you the most steering? This is for the 17.5 blinky mode. Thx

I finally got to race the car yesterday, and it was pretty good. I started out with the kit setup, and really liked it. I wanted to tame turn in, so went with the +2 inserts, added another .5mm washer on the inner stud, and matched my best lap time with my 4.1.

I added .5 washer in the rear for the main, and quickly realized that was a change for the worse. I wasn't on the ideal tire, but still managed to qualify and finish in 2nd.

Is anybody else happy running the kit springs?

edit: Almost forgot, I also went to the 1mm anti-squat shim. Time to make a setup sheet.

I ran Tebo's CRCRC setup yesterday and it felt good, only thing I have different is .5* hubs since I wasn't on a super traction track. Car is easy to drive and consistent. I like it a lot, I feel much more relaxed with it than a B4.

Thanks in advance
Found this:
Special Assembly Instructions:
Keep kit supplied gold Kyosho topshaft spacer. In instruction procedure, do not use AVID thick topshaft spacer (black). Replace the thick AVID spacer with the included gold kyosho spacer followed by 1 thin centering washer which will keep the inner slipper plate centered on the topshaft. Otherwise, assemble per instructions and use the included M3 slipper nut (5.5mm hex).

The Triad itself comes with an instructions card...and the Kyosho topshaft you bought from them came with another instruction card, find that one and you're golden. I keep mine in my pit box for this very reason.

Speaking of hubs... I have a set of Kyosho gunmetal .5* hubs that I'd be willing to trade for gunmetal 0*.

The "team drivers Japan" setup on petit rc is very steering aggressive and would probably be a good starting point.
