First Kyosho Kit I have ever assembled - extremely impressed with the quality, fit and finish. The shocks reputation has been confirmed in my opinion - they are money!

Can't wait to get it dirty...

Default Setup
Does anyone have a good baseline setup for the kit stock car or point me in the right direction? Will be running on a high bite indoor clay track and will be the first outing with the Rb6.

Thanks guys.

Built the stock kit setup first. It's pretty dang good right outta the box! Then minor changes will most likely get you where u need to be.

Last night I played with the front hinge pin block, changing from 25 to 30* with a .5 shim on and off as well. 30* block with no shim reigned supreme at the track for me. As I felt this car has been slow mid and exit cornering. 30* gave me a tighter faster radius mid and exit. Initi corner entry really I felt no difference between the few options I tried. There is a little write up about this on petitrc in the rb6 setup shee area. Next I will play with the castor inserts. I am at 2* right now. So I believe I was at 32* total? Felt good

Yep.. start with the kit setup and you will be just fine. The car is ridiculous right out of the box. The only thing missing, is shock oil. With the stock 5 hole pistons i would start with 37.5F 32.5R and tune from there.

I noticed that in mid config Tebo ran the RB5 wishbones the opposite way round. Does this shorten the wheel base?

This is probably a really stupid question, how could I tell which degree of caster am I running...? Thanks

There are two ways to change your caster... with your front suspension hanger, and inserts that go into the caster blocks. Look under the bumper at the bottom of the front suspension hanger, and you will see 25/30 underneith, whichever is facing forward is how much kickup caster you are running. Then you can run 0, 2, or 4 degree inserts in the caster blocks themselves for different combonations of caster (i.e. 27, 29, etc)

Not sure if I will run it outside - may just keep it as an indoor clay track whip. I love both tracks - my attendance will depend on Sydney's softball schedule.

I ran it for the first time Wednesday night @ Redneck. I raced on the wrong tires, but borrowed a set after the races and ran some practice packs and it was a different car - so impressed with this car. Killer whip.
