The RZ6 looks amazing. The conversion alone is as or more expensive then some entire kits.

But, Kyosho is worth the money. I'm having a hard time bleeding the shocks, they are smooth. But, oil is all mixed with bubbles, I understand the bleeding idea but, once I fill with oil and get all the air out its to much oil, and the shaft rebounds.

If I use less oil, Air stays inside.

Is it OK to have some rebound?

What's a good starting weight oil?

All I've got is 27.5/37.5

The RZ6 is a conversion for the RB6. It's not a whole new kit.

This video Tebo did in shocks is great. Give this method a shot and make sure you're bleeding from the bottom, not removing the cap

I enjoyed this kit so much, I ordered another Kyosho RB6!

Kit is finished. I'm doing the body white, now I just need my Orion R10.1 Pro, and a 7.5T motor!

Great kit to build!

One thing I recommend about the entire kit... The plastic is hard like no other, it's like hardened polymer! So hard in fact, you will strip the included hex heads.

Everything is nice and tight!

I got a really good deal on a Trinity D4 10.5T

It's a certified Trinity D4 motor with dyno sheet, and a high torque 13mm rotor.

Think this will get the RB6 moving OK with some 100C 2S packs?

It should make it rip. Gear it for the track you normally run on. Kcars simply rock.

This is a good question. Every other manufacturer offers this. It would be so easy for them to do. What's the deal Kyo?

I liked the video but I always struggled with putting in just the right amount of oil so I went back to my old routine.

Fill the oil up to the first thread.
Extend the shock shaft so the eyelet bottomed out on the shock bottom.
Place the piston into the shock body but let gravity pull it down into the body.
Once the shock bottom reaches the shock body help align it into the body so that the treads line up.
Turn the shock bottom so that it starts to thread into the body.
Wait for 1 second to give the excess oil time to escape.
Continue to turn, wait, turn, wait process until the shock bottom is tight.
Pump the shock shaft a few times and then bottom out the eyelet to the bottom of the shock and release.
Hopefully you should not have any rebound or maybe just a little bit.
If you have more than you like, loosen the shock bottom, push the shock shaft down, wait for a little bit and then re-tighten the shock bottom.

I hope that made sense.

That actually does make sense. I'm gonna try it again. I did all the shocks before as good as I could and put them on the car. They are smooth, but I suspect there a tab bit low on oil.

I don't really understand the whole 3 gear, 4 gear thing. But, I do realize there is (2) idler gears in the mid motor RB6 transmission, both are black . If we replace it for aluminum, Do we replace both of them?

You don't want to run metal on metal so you would replace the plastic gear that touches the diff gear.

OK, I've been looking bargains on Rctech, to finish my Kyosho RB6. Plus, another RB6 15' kit is on the way.

How do you guys like the Trakpower 100C 2S saddle packs? They are a little heavier at around 275 grams. I got a pair on the way.



I ordered those.
