Tebo ran mid motor, so did the rest of the Kyosho team, my son Brandon tried it but didn't have saddle packs so it didn't handle well. He ran rear motor with Tebos WCRC setup, and made A main 13.5 after 3months with the RB6

Tires are huge along with set up.. Sounds like you need to post what set up you have and what type of surface you're on

Running Brandon's latest with 30kickup 0 caster. Surface is indoor clay. The track is the only clay surface I've ever run on so I don't have anything to compare it to.

Tires I have

Front: all softest compounds the brands offer. Using the open cell that came with tire.
M4 Suburbs
Hotbodies Pink Fullslot<------haven't tried these yet
Jconcepts Green Barcodes

Suburbs and Barcodes felt about the same didn't really like 1 over the other

Rear: both with AKA red insert
Jconcepts Green Barcodes v1<------easily the best
Hotbodies Pink Beams

Rear traction I have for days. Could probably use a touch more forward bite on launch in straightway. Can tend to fishtail a bit. Side bite is retarded good.


Here's my track for reference: http://www.youtube.com/watch?v=TZvgZStURA8 the features seem much bigger in real life.

I have an issue with front wheels. With the stock rb6 wheels there is no binding. With avid wheels I have serious binding. After inspection I noticed that the avid wheels have a different offset on the inside of the wheel. Is there a way to fix this problem so I can run these wheels?

I run PL wheels that have a larger offset I just shimmed the hex out with the 1m plastic washer. LHS was out of Kyosho wheels

Tebo I think runs aka wheels and he runs parts UM506/LAW30GM to compensate for the larger offset

Can see a good picture of it here: http://www.petitrc.com/setup/kyosho/...ace2013012427/

3rd from the top.

I run the AVID wheels with the RB5 axles and hexes... UM506 & LAW30GM. Car steers much more consistently thru corners (both ON & OFF power), with this axle setup too with the slight addition of unsprung weight.

Keep in mind that Brandon's setup is for 17.5 blinky. If you are running mod you will get more weight transfer

The offset is right, but you need to make the hex less shallow on the wheel to run the thin axle setup on the RB6. You can try the RB5 setup as mentioned without modifying the wheel.

Keep in mind the traction level at the cactus was unreal. It was like driving on sandpaper. Not your normal club race type of track prep for sure.

Ya I know that race was a special case as they were going through tires after 5minutes of practice but even if you watch their wcrc race which Tebo called medium traction the car looks soooooo much more composed then mine.
