What am I doing wrong?

Actually you're not doing anything wrong. The solution is to enlarge the hingepin-holes. But only sideways. That makes a little room for the holder to move as the cam is rotated.

Use a thin round file, and make the hingepin hole slightly oval from left to right. It's a bit of work but the result is worth it.

Really? I knew it had to be the alum. bracket because I just put the plastic one on and it works fine. I worked on the hinge pin holes for a while just to get them to rotate. I guess I will work on them some more.

Thanks... again

But only side to side. Try not to enlarge the hole up or down.

Well after filing a bit I got to work. It's still a little tight but time is running out. The front end falls under it's own weight but not as fast as I would like it. I figure that it will loosen up a little after a few crashes tonight. The good news is that I got the droop perfect... thanks to your article.

I'm heading to the track tonight to try a few things... gear diff, front spool, new shocks, relocated DRS arms. Yes, I know, only make one change at a time. I am trying to make direct comparisons between the shocks and the front diff/one-way/spool.

Wish me luck. I will report back tomorrow with my findings.

Sorry, did you mean Kyosho 2000 & 3000 or 20,000 and 30000?

Thanks for your further info. I only have 30K and 60K in hand, so I guess on race day I need to mixed them up

Also, congratulation on your new little one. Hope she will bring all joy, luck, and prosperity to all your family.

Will serpent be delivering silicon oil? And if so, what are the parts numbers?

Ah yes... testing testing testing and testing eh? :P

Will the bottle's be bigger? The serpent oil and silicon-shock-oil bottle's are way to small and (well, i think) a little too expensive. I use the triniti silicon oil because it's the same price and i get 2 times the amount....

True but not twice in price, Xray is (at least in S.E.A)

Default Gear Diff

I got a chance to try out the new gear diff and it worked great. I put 10,000 wt. in there first (that's all I had) but the rear was sloppy. My friend gave me some 30,000 at the track and that worked much better. I'm going to try 50,000 next time out.

I'm still experimenting with the front end. I think the locked one-way will be the ticket if I can get a little more steering. I tried softer front springs (yellow) and that helped some. I am goint to try disconnecting the front sway bar, opening more holes in the shocks and softer front tires to see if any of these things, or combo of things, helps. Any other suggestions? The car is just a little slow thru 2 tight areas of the track compared to my friends RRR. The car is an absolute rocket from corner to corner.

For faster direction change, try playing around with the front roll-center.

I prefer harder springs in the front too, the yellow is just too sluggish but at the end it is the combination of these.

Harden the front springs and make the rear diff tighter. Worked wonders for me... but then again,i'm not that experienced..
it seems (in what i see/think) to give more steering out of the corner, but that's basicly from the tighter rear diff, the softer springs seem to soft and make tires 'search' for grip and let the front roll too mutch....
the harder front springs seem to give more presure on the tires and the front doesn't roll as mutch...

but, i'm very unsure in this...
