you're always going to see lines, the graphite is woven so there are layers running all the way through it You just need to sand it to take the sharpness off the corners. Some people say go as far as to creat a totaly rounded edge, you'll be forever if you try that though, I just try and get a nicely smooth corner, still with a defined flat edge.

I try to keep sring rates close front to rear, normaly within one grade but often found one rate stiffer up front helps balance the car for me.

On the same theme, whats this "magic" combination of Rayspeed springs Dave keeps saying he likes and I think KO too, reds and whites I think but which way round.

What size would they be and who might I get them from
Thanks
There were screws in my kit that I used for set screws, they are the same as those used to attach the top deck.

Arrow R2 Spring Ratings...

Does anyboday have a chart that will give spring contant values for the R2 springs available on Speedtech. I'm used to the numbers on Associated/Yokomo style springs and they are expressed in pounds. I want to get some R2 springs but want to know how their numbers will compare to what I already have.

Thanks For the Help!

Wink Pal hollow graphite drive shaft.

to all....or Dave,

What type of motor limit can you throw at the Pal hollow graphite drive shaft

I have run it with stock no problem, but was considering a 19T motor.

your thoughts?

thanks,

JC

How well do the Delrin Diff Halfs hold out? I've only run off road before and I can't imagine using delrin diff halfs despite the weight savings.

(sry if this has been asked before)

Also, how many people run the lexan gear covers?

thx

while iv been racing the car it hink the outdrives are exelent and hold up as well as any other outdrive may be and i think most people only run the gear covers if there on a track with lotsa little stones or debris that can chew up the gears so if your track is fairly clean u will be ok running without them

Delrin diffs are fine for touring, they're fairly solid and I plenty strong enough for most crashes. You get very little wear on the outdrives, thanks to Delrins self lubrication.

It gets easier when you learn the technique
I make things easier by taking a sharp scalpel and taking a VERY small amount off the corner of the two tabs so it's angled to help stop it catching on the bearing when going in but has all the normal surface stopping it from coming out of the bearing. A little shock oil can help it slide in easier too.
I then squeeze it with pliers and put one side of the join in first, so it's at an angle when I'm pushing it in but both tabs are in contact with the bearing. Once the tabs are inside the bearing a good hit with something heavy will have it in place. Then comes the second bearing which is tricky since there's no plier room because you're putting it in the shaft holder. I line up the gear as before, trying to ge the two tabs to start squeezing in and place the gear on a table and then hit the shaft holder with something heavy, a hammer if you've got one. If it's lined up right then it goes in reasonably easily.

You should have two small grub screws, the same things that are used in pinions. Make sure you put some super glue on the flat section of the carbon shaft before you assemble it though and let the glue dry so there is a hard sruface for the grub screw to tighten onto.

okay, chck, get some diagonal wire cutters,(dikes), because it has a narrow cutting area, you can use it to squeeze it enough to slip it past the bearings. I have replaced one pinion gear and then installed aluminum shaft holders. I didn't have any trouble, you just have to be careful. I never used shock oil or anything like herm, but it could help. Once you get one of them, the other will be easy...hope this helps. I know this picture isn't the one I wanted but here it is. They are the 7 inch model, not those real small ones.
