I snapped a rear in the same way, just driving it slowly round the lounge floor, adjusting steering trim. Arm came right off, without much resistance. Ive since orderd 2 complete sets of the graphite arms. Hopefully they will get here soon, car has been busted for about 2 weeks and hasnt even had had a proper run yet.

hopefully losi will revisit the a-arms in the very near future. with the ease that they're breaking, and that it's fronts and rears, it sounds like a materials issue.

personally i think the reliefs cut into the front arms, especially at the rear of the arm, might be a contributor.

a material issue could also be why some of the factory drivers who have been running pre-production cars for a while now haven't had problems. production kits probably have a different production run of arms.

but that's just years of mechanical / manufacturing engineering thinking out loud...

with all that im hearing and seeing here, indeed losi needs to revisit the amrs issue. maybe going back to graphite is an option ... maybe the two pounts raised Russ is the issue ... in the end i hope it is resolved. dont want an rdx experience with the type-r.

Are any of you guys that are breaking arms (front) using the Parma bumper?

When I had my RDX - and even the '007, I was breaking the odd arm as well... when I added the Parma (or P--Dub) bumper to both cars, the arm breakage almost completely stopped. I just got the Parma bumper for the Type R from Horizon - I'll let you guys know how it works for me after this weekend.

I've got about 15 runs on mine with the PDub bumper (haven't installed the brp yet) and haven't broken anything. I've had a few solid hits, but they've been head on for the most part. I watched another guy at the track trash a front arm with a glancing blow.

Bumper would not have done much to protect my rear arm the way it happened. I do have a PDub and had them on my old cars as well. It was not even a hard hit and it just snapped. I actually was on the brake when it hit. If I knew it would not bork the hole setup up, I would switch out to the old arms since they seemed to be a bit stronger. I am not sold on the EA3 stuff and noticed at my local dirt track people with XXXCR's are either dumpin them for B4's or switchin out all the EA3 parts with the graphite stuff. They have been breakin chassis's like you would not believe. I don't want any part of these arms if they are gonna be that bad. Either improve the material or go back to what worked before.

I broke a front arm with a "slight-tap" as well last week... I hope the bumper stops this as I really like the way the car handles on the track. I do have a full set of graphite arms at bay just incase.

Since EA3 is more of a plastic - maybe boiling them will help? I'm gonna try with one set once my spares arive (this week I hope)... has anyone else tried boiling the arms to make them a little more flexible? Worst case scenario, I can add some broken X-Ray C-hubs and some corally arms and have a nice soup.

to be perfectly honest with you, the only ea3 parts left on my car are the steering bellcranks and the rear a-arms. the only reason the rear arms are still on is the length. i changed the rest mostly because of setup changes, but i did strip out a steering knuckle by accident.

Are there graphite arms that directly replace the EA3 arms without having to change wheel base or whatever? It might be worth having some on hand to see if they do any better.

The graphite arms as far as I know are just the ones off the old car. You would have to have the LCD and CVD's from that car to make the new arms work. They are shorter then the current arms but are able to be used as a tuning option on the new car.

You can run the old arms with the same LCD or RVD from the R. Just use the outside hole on the suspension mounts for the short arm.

Blake,

Probably not. I just went on vacation starting today. I work every Weds. night, but I will take a Weds. off here and there. I will get you my set up from there. My car was REALLY good tonight.
