Center it up and let it dry until the thinner has evaporated. Kimbrough use to make a molded plastic cone that made putting the donuts on really simple, but not sure if they are still available. I think I saw donuts on Stormers site.

To get the old rubber off the rims, just soak them in paint thinner until the donuts literaly fall off.

Thats the way this old guy does it, I use laquer thinner and contact cement. I used to get my donuts from rc4less and he was the guy I got the plastic cone from. They used to call it a shoe horn in the olden days(back in the 80's). I had to ask the guy at rc4less for one because he didn't have one listed on his web sight.

Check with them, they are great to deal with.

Yep thats the best way, I got some donuts form CRC about a yr ago so you could check there also.

Just be careful which rims you use...some of the more modern rims will melt or soften in the lacquer thinner.

Yep, I'll be there. While we are on the topic of tires. how small is too small? I have a ton of tires that are really little and after shaving .080" off the front arms I can run something as small as 41mm/1.61" and still have 4.5mm chassis clearance. And after seeing some guys running the new big rims with virtually no rubber left on them, I'm curious if tires this small will handle OK.

glueing tires.
 
there was a thread on here about a month ago explaining another method of mounting donuts where a guy used slow jet for a more permanent bond. also last i looked stormers had the crc donuts in stock. Kimbrough makes the tire horns for 1/10 and 1/12 wheels. I tried his method seemed to work fine and feel more confident that the adhesive won't come loose.

Shawn.

I would think that would make the push worse?

I like a TON of steering so I usually run the CRC 45 front spring rather than the kit 50's.

Shawn also brought up a good point about the black fronts. I've been to tracks where fronts in the purple/pink family just won't work, and a switch to gray or black fronts REALLY wakes up the car.

I have no clue what front springs are in there now but they are in good shape with just a touch of end play, no pre-load. honestly I have no clue what car it is other than a crc. It has the upper machined delrin a arms with an alum 5 deg block.

Would asc .018 be too soft? Not sure if I could find crc springs around here.

Sounds like black might be the same family of foam as the grey so it should hook up better, not just a super hard tire that I was told it is. Now I have a lilac on there now, is that the same family as purple/pink? Sorry, very new to the foam stuff.



Ok, if I could have 2 or 3 complete sets of diffrent foam for diffrent tracks, what would they be? A natural rubber set and then a synth rubber set ??

Hey guys, does anyone have pics of a T-bar car running lipo?

The other week I saw a "quick-release" rear ball cup on a Carpet knife shock. It was obviously aftermarket and my friend who had the car got it 2nd hand and had no idea who made this trick part. Any ideas? I loved the idea of just sliding a spring loaded collar to remove the shock to toss a battery in. Sure beat using pliers all the time.

I picked one up the other day and I think it is made my Sullivan (they make a bunch of RC aircraft stuff)...I'm not at home at the moment but I'll double check when I get back.

EDIT: just found it on the Sullivan website...scroll down a bit (locking sleeve ball joints) http://www.sullivanproducts.com/ContSysAccMainFrame.htm

I'm prolly going to pick up a new 1/12 scale car in Jan. and build it for stock class. I'm going to be 35 so I can run masters now at Cleveland. If you had no parts, and no loyalty to a brand which car would you buy? I've had AE, Yokomo, CRC , and even delta 12th scale cars in the past.

As of right now I like the Serpent S120 but my local hobby store is not hooked up with them as of yet. I was also wondering if the serpent has it's own make of wheel or is it the same mounting as a Jaco type wheel?

Please discuss.

Thanks

If I were looking for a t-bar car, then the Serpent would be the one I'd pick right now. I drive a FF07, very similar to the serpent, but it's not available as a complete kit, just a chassis conversion. If you don't already have a t-bar car to use as a donor, you'll need to get a ton of stuff to complete it. You'd need a complete front end, shock, damper tubes and hardware, antenna mount, t-bar, pivots, and hardware, rear axle, diff, hubs, and all bearings.

The Serpent is a complete kit. A bit spendy, but well worth the $$ from all accounts.

Serpent did the smart thing and went with standard wheel hardware for the120. You'll be able to use any standard 1/12 wheels.

I was thinking that too but for 4 bucks I may give it a try. I will be at the Track this Sunday.
