Yep...me too.
The stock arms are softer and more flexible.

I need to start flipping the arms after every race night as Craig suggested to minimize the warping. The constant force of the shock on the front part of the arm is causing it to warp.

But we shouldn't have to flip them! I came from 1/8 scale nitro, and it didn't seem to be much of a problem. Losi 8 has been known to warp, but never saw other cars with the problem. Any one have to swap you AE RC8 arms?

Stock shims are .2mm each (at least, that's what they are specced at....)
I found that one under each gear was too loose, and 2 under each gear was too tight. If I put one under one side, and 2 under the other, it seemed just right. (I feel like I'm reading Goldilocks and the three bears to my 4 yr old!)

Since I don't like the idea of uneven shimming (not sure why...I just don't!) I decided to try to find some 0.3mm shims. Xray has some 5x15x0.3mm "washers" that fit perfectly, and with the extra outer diameter, they seem to allow less play too! Zero parasitic drag.

That's what I've been running, and 3 rebuilds later, the Xray washers are still in perfect shape.

I agree, but we do. You have three options:

1. Remove and flip the arms once a race day.
2. Don't and replace them every two race days.
3. Don't run the truck, or figure out how to wheel it with all the bound up hinge pins.

It sucks but it is what it is.

Anyone try these out? I just ordered their 6 pack special along with a bearing kit for my sc10, can't wait to try them out........

I accidentally quoted the wrong post (serves me right for screwing around on my smart phone), but I saw that one too. Last time I saw that many holes I was draining pasta.

I used .3mm thick washers from Ofna and they are perfect as well. Definitely the way to go when shimming the diffs.

I warped several sets of stock arms, but have been running a set of RPM arms for 6 months and haven't been able to measure any warping... maybe it's the cold climate up here.

For those that had been asking about prices on parts, a good chunk of parts are going live in 10 minutes on my website.

Do you race mountain bikes by chance? I've never seen any one as gram concerned as that group.
You must not know many RC air guys. For 3D planes we even take the plastic covers off our servo extenders and wrap them in cheap electrical tape instead just to save .5g

The back triple is so big there should be a skull and crossbones warning sign on it.

What I like about TRCR is how clean I could keep my truck! And the bite, man 2wd would be fun. But.. I want a little longer straight.
I hate straights I love to be airborne I wish every straight at my local tracks were replaced with rhythm sections.

Doing the very same, the wear I'm seeing is the brass bushings in the diffs are shot, the bearings in the hubs are all shot and need to be replaced, the plastic idler and bearings for the belt need to be replaced, the hinge pins needed to be polished (2000 grit wet sandpaper), shockshafts and o rings needed to be replaced..other than that everything was good..I just got a Boca bearing kit and replaced all the bearings, I also got the FT kit and I'm installing it, bought a new chassis off eBay ($19 shipped)..I also got a set of RPM arms, so when I'm done it should be like a new car..

I built a set of the bearing modified cases on my mill, but you could do the same thing with only a piece of 120 grit sand paper and some elbow grease. AE will eventually come out with one with a steel bushing, but I don't know if you want to wait that long for a fix you can do yourself with $5 in bearings.
I got their first batch calling RPM direct and I still have the same set of arms from RPM. I mailed my warped stockers off to Chris. I'm not sure why those are warping cause mine are spot on. Guess its a flipside to WC's howling that the AE arms are "perfectly fine". As for the steel bushing Diffs, AE is making them. But like Craig says, Don't wait.

Not happening anytime soon.

Yeah. The RPM Taboo. These things are beefy and rigid.

I bought a set myself last night. Only worried how rigid they are. I like Wheel flex. We'll see!

That's rediculous! None of our Pole Racers or IMAC guys do that. Wow.

I did the prototype testing for the wheels. These are the nicest wheels in the market if you ask me! It's the little details that count.

They are lighter, they have an awesome bead that makes gluing a lot easier and they have the counter-serration "vortex" that work awesome with serrated wheels.

They are also stiffer than other wheels, which made the truck feel more precise.
