Hey DriftDreamer06,

I like the R5 front end because of the on the fly adjustments you can do.

Don't get me wrong the old Associated work's equally as well.
Hope this helps
Mike

That's what I like about the CRC front end...caster adjustments are super easy as you don't have to take out the hinge pin to do them. I just wish they used a turn buckle upper arm instead of a pillow ball.

so long as you are OK with running the CRC front end with the longer upper arm length, then you can use a turnbuckle upper arm in lieu of the standard CRC pillow ball setup. That's the way I run my car. I use the excellent CRC lower arms and CRC caster blocks, the optional CRC graphite brace that moves the caster blocks inboard to the long arm position, then I use CRC's older version standard upper arms (not their new ones with two sets of pin holes molded into the plastic), then I use a dynamic stut AE short upper arm turnbuckle, AE upper pivot ball and socket, AE kingpin, AE steering block & axle. It fits, it works, and it's almost bulletproof. it's only necessary to remove a small amount of length from the upper arm's plastic so that you can get to the right camber adjustment. Everything else fits without modification. My car's been setup this way for 2 years with no issues at all. It's the screw-in kingpin that I didn't like about the new CRC front end since those kingpins bend so easy (and you can't tell if they are bent unless you take them out to inspect). Also I wasn't keen on the fat CRC axles that required the big hole front bearings. Those don't last so long and they also tend to get sloppy. The 1/8" ID front bearings are much better. My hybrid front end is darned near bulletproof.

I thought about doing that just never got around to it. I had problems with the older upper arms not threading the long ball straight so I didn't want to risk the turnbuckles on that set. I switched to the long upper arm with the short ball and the front end is nice and square now and ran great at the IIC. Haven't ran much since then as my local race died out so now all we have running is TC and are just now starting up a F1 class. The track we are at now gets really crappy grip for foams and won't let us sugar water the track for better grip so pan cars other than F1 just aren't going to get popular there.

That reminds me...ever thought of doing an F1 Jason? A BMI conversion for the F103 or F104 chassis using the Copperhead rear suspension would be killer! And a BMI rear pod that takes the Tamiya ride height adapters would be even better

Also...how's that new front end coming

hey can you post some pics of your front end.
i have a db12rr(stock) and i am thinking about the "CH12"(cooperhead 12), i have been running a 12r5(mod) and like that front end more than the older.

pics would be cool

Jason was at Adrenaline with us last weekend with his Copperhead, and dominated the World GT class.

Hey Jason, Tim Potter's Copperhead is already dialed at our local track and I believe he won our last 1/12th scale race by at least 2 or 3 laps. He's doing great with the car on asphalt!

Not to mention how sweet the copper anodizing looks! Much better than the prototype you had at the 'birds, in my opinion.
