i think going to the +4 caster in the hub will be my next move to calm down the steering.. the rear is locked in. how is the balance dropping the rear spring one rate?

i see ppl are going that route.

Are you running MM, or RM? I thought I saw you mention you were going to MM.

I am running RM, and find the pink/red front and rear combo to NOT be ideal with the weight balance of the new car. There is a lot more weight on the front of the car in comparrison to the rear than there was with the RB5, and the car has a bizzare amount of steering. I am running golds front and back and it feels a LOT better. (37/30)... but still have a lot of testing to do.

i wanted to at least get a base with rear motor. so you went up two springs in the front, dropped on in the rear. using 0/2/4 caster? and where is your battery?

Im running the 4 degree caster inserts, and im running a full sized normal lipo right in the middle of the car in front of the ESC. I have since moved to the RB5 carbon fiber battery strap, but here is a shot with my battery and wiring:

I like using the RB5 battery strap in my car. Keeps my lipo in place much better then the plastic Kyosho part. How do you get those inserts out of the caster blocks. I want to try 4 degrees but those suckers are in there good.

Didnt know if there was a problem with doing this, I just thought it was alot neater in it.
I'm using the channels, although, for the esc wire not the servo wire as my rx is mounted directly behind the servo

Buy new knuckles . How did you use the rb5 strap though guys? I just checked the holes are wider on the rb5 than the 6.

They are a b1tch! I punched it out with a big hex driver... one of them flew across the room! I used black grease on the outside of the 4s before I installed them, so hopefully they pop out easier if I ever have to take them out. Careful not to stab your hand!

there is another set of holes in the rb6 chassis. same width as the rb5. More towards the middle of the car. I dremmeled my RB5 battery strap nice and short. You have to use a 2mm shim underneath the rb5 ALU battery posts, and it works like a charm.
