the o rings provide a quicker rebound than the foam does so the shock responds faster.

Makes sense. Can you use any old o-ring or is there a specific type to use?
What about my piston dilema?

Azenis, if it were me I would use the #2 pistons front and rear and drop your shock oil weight by 10wt. Use 45wt front and 40wt rear. This should be a close simulation plus you will still have balanced dampening front to rear by using the same pistons. I cannot comment on the o-ring in the shock as I have never tried it before. Hopefully Thad, Erik or somebody that has used the o-rings in this manner before can elaborate more for you. Until then I would leave them out just to be on the safe side.

JohnB: Thanks! Also, we are looking at a running change for the C-hubs. For now the fix is either a little heat to bend the C-hub or to file the steering block until it moves freely. We're working on it.

Erik:

How should I gear 4' castor blocks as opposed to 2' or 6'?

Man-those are some long caster blocks!! 2', 4' and 6'!!

I'd gear the 2' at 0.90

The 4' at 1.05

and the 6' at 2.00

Hey Erik good to see you around again, is there anyway to make the steering block a little more durable, I keep braking them at the bottom screw position. Also It would be nice if one could just buy 2 steering block instead of the current packaging. Please tell your people about this that would be a nice change.

yes...definately..packaging the steering knuckle and rear hub seperately would be benificial...

if racers are breaking the steering knuckle alot more...what you're left with is handful of rear hubs gathering dust...

or another option is post a parts trade in the for sale/wanted threads

Very true! Associated does the same thing, with the TC3. I can't tell you how many rear hubs I have in my pit box.

Pucho.....I was having the same issue....so what I ended up doing was using XXXS graphite steering blocks. They fit right in the only thing is that you need new bearings and new CVD axles....I used TC3 ones and TC3 hex's. The only real draw back to this is that you dont have the back hole on the losi block. The losi block only has one hole and its in the same place as the forward hole. I only did this b/c I was tired of replacing the steering blocks too often....and one to a package also sucked. Once I did this change I have not had any more breakages.

Kevin thanks for the suggestion, I have most of the parts available. Question is what kind of effect did it have on your handling? Steering?

Default rubber tire questions

Ok all you west coast rubber tire guys help me out with this.

With track temps around 100-125 what tire/insert combo would you start with. The track is med/high bite treated with sugar water.

I normally run on carpet with foams and rubber tire are still kinda of a mystery.

In Connecticut we dont get the super high track temps.

I have tried 32r and 36r with hpi blue med/hard insert and car seems to push badly.

I tried 28r with hpi blues and tires seem to overheat and wear quickly but car has improved steering.

Can I get more steering by running a softer insert med or med soft in 32 and 36r's.

Thanks for the info

Jamie
