Just bought my second RB6 and realized that I've never run either one of them with a full size pack. Any opinions on the differences between shorty and full packs in this car?

I've tried the full pack when I first built the car, I find that with the shorty pack the car will jump better and will corner better too. I think with the full pack... The car is too heavy.

I figured it out right after I posted it lol and it was the kyosho rebuild kit.

what should gearing be on a 7.5? I will probally turn it down to around 85% since its a pretty small track.

what spares do I need
Kraig: Things that have carried over to this car from previous generations that people have replaced are, rear hubs and rear hinge pin carriers. While I have been fortunate in not needing to replace these items others will say they broke them. Your experience will vary with these parts.

The new rear hinge pin carriers allow you to adjust rear toe and overall rear width of the car. See post #1 for what changing the width does. If you do purchase some bling definitely go with these.


what do I need to replace befor I race it
Kraig: the only thing in addition to the above items you may want to look at the steering rack. While I haven't broken a plastic piece I have purchased the aluminum piece from Exotek and Kyosho and have not had an issue since with them. They very well could have made changes to the mold for this piece but I haven't kept up on that.

and what up with the rb5 front alxes and hex hud in the front instead of the stock rb6 front alxes/hex??
Kraig: Nothing really. Jared runs them but I haven't had the opportunity to ask him why. I think one thing this does is that it allows you to run non-Kyosho wheels without the wheel actually rubbing on the steering knuckle. Then again I could be completely wrong and people will correct me.

where do I find the 4 hole 55 shock pistons?
Kraig: the 4 hole 55 piston is a Losi shock piston. You have to buy their bag of pistons to get what you need.

Now if you have your own set of drill bits you can pickup these, KYOW5303-08. These are blank pistons and which allow you to drill your own size. These have little dimple marks in them to help keep the drill in one spot as you drill your holes.
I answered your questions above.

One thing to keep an eye on his the front hinge pin brace. If you take some hard or have some weird landings it may bend. They did redesign this part and the new ones have a line in them right in the middle. I don't know if this new part made it into the kits or not but the part number is KYOUM720B.

Have fun!

GHEA makes some tapered 4x1.3 size pistons, GHEA8114.

Associated has some tapered ones too, ASC91350.

As for flat/regular ones, obviously Losi has them which is part of the shock piston package for their 22 line of cars. The Losi ones are thin so they will move up and down on the shock shaft in between the e-clips.

Associated has some flat ones as well, ASC91353.

You could get some Kyosho blank pistons and drill your own too. Although they are not tapered like the others but are not exactly flat either, KYOW5303-08.
