I'm lucky I'm a machinist so I get to make anything I want for free !So I was thinking of making a set of adjustable upper arms to adjust the camber, and save a few bucks too! But does adjusting the camber help the handling that much or is it a waste of time. Thanks for your reply.
 
go for it dude. I put the HPI adj uppers on mine, and it did wonders for the handling. If you want some dimensions I can mic mine, HPI uses the turnbucle spacing to determine the camber angle (ie. Xmm gap = Y degrees of camber).
 
mr machinest.. i have a order for you... i do not want a turn buckle design.. makes a weak link IMO, i would like a stock upper arm that has a hole like a engine mount slot, then 3 C shaped piece of plastic that i can use on it to shim it in one direction or the other. aka 2 thin ones and 1 thick one, so i can run stock, a little neg camber, and way neg camber by swaping pieces in and out.. if u can do that for me.. I'm interested.. else ill build my own..

in theory i would prefer the C to be hard plastic, aluminum will wear, metal will wear on the bolt thats in it.. so i feel a nylon to hard plastic will be longest lasting..

why this design.. i fell it will be the strongest design of them all..
 
I agree, somewhat. I set mine to 3 degrees (all the way in) and I beat the snot out of my savage, and I haven't had any problem with the uppers yet.

If you're concerned with wear and durability, why not make it simpler and machine different uppers of various lengths. This should be rather simple if the machine is CNC and you have the layout on disk. Changing the uppers is not that difficult and it would eliminate any small parts that could get lost or wear out. My dad has a full shop, but none of it is CNC. I plan on cutting some steel spurs soon, just have to figure out how that dividing head works.
 
Thanks for the ideas guys . Error401 you said you had yours set at 3 degrees, could you measure the spread between the two pin holes , I like the idea of one piece but do not know the hole spread for 3 degrees. Then I would at least have a starting point for if I wanted to make 1 or 2 degree arms. CRSMP5 I wouldn't mind helping you out but my wife is frowning on me working late at work ,and not with her and my three kids the way it is, can't say I blame her, sorry.
 
No problem, like I said, HPI had a table in the instructions for the various camber angles, but I'll have to mic the hinge distance and then work back from there. I'll edit this post when I get it done, shouldn't be that long.

I have the Golden Horizon aluminum upper arms and I just can't see where they create a weak link. You have a heavey aluminum arm and a rather thich turnbuckle secured by set screws. This is basically the same setup as on my Athlete buggy, with the exception of aluminum vs plastic ends, and the Athlete has survived some herendous wrecks. I would think the weak link is more the area around the hinge pins where they attach to the bottom of the differentials. This has been the location of several failures on my buggy. I have not yet "broken" a part on the Savage (plug for HPI).
 
pee wee, I mic'd one of my uppers and the distance on centers is 109mm for 3 degrees camber. I can't find the sheet that came with the uppers, and it had the numbers for 2 and 1 degree camber. I'll try to find it again, but I might have lost it.

Whitt...
 
first off.. aluminum moves th eweak link to other things, so i refuse to use aluminum on suspention components cause i like replacing 5$ items instead of 20$ items.. 2nd the weak link.. the thredded rod.. all it takes is a tweek to it to break.. I'm way hard on my equipment.. broken 3 uprights in 2 weeks even.. so... i need cheap strong stuff vs somethign expencive..
 
Whatever, but I disagree one the weak link issue. Maybe I'm just not a "Go All Out and worry about what breaks later" person. I work hard for my money and can't afford to throw it away for the thrill of a single great jump. My brother is the all out type but then he will wreck and break something and then laugh. To each their own, I guess.
