Have you raced them much? How are they holding up? I haven't broken any of the "new" Losi arms but I do worry whenever it tumbles after a jump. I would be interested in some. Thanks!

Raced with them again last night in mod. Took many tough tumbles, cartwheels, and bad landings. Broke a front outdrive and a one-way on the process. Not that I'm a terrible driver, but the car can get away from you if you're not careful!
Still have yet to break a production version and I don't hold back when I drive the car now. That's the biggest complaint I hear about the stock arms. Drivers afraid to really drive the car hard.
The only break I've seen was with a prototype arm with the old design. The inner pin hole was drilled too close to the edge. It broke when I ran the car at a 45 deg angle intoa cement curb at full throttle with a 10x1 Flatliner. Also broke the hinge pin, diff cover, pivot support, and bent a shock shaft in the same wreck. The production arms are squared at the ends and have about 15% more material at the inner hinge pin than the protos.
My arms are also much stiffer than the stock or even the graphite arms. They don't twist at all. They also offer more lower shock mounting positions.
If you want a pair they can be purchased at my site: www.dpmracing.com or just email me at [email protected]

I think your next project should be caster blocks and steering spindles. That is the only thing my son and I have broke on our cars lately.
You are 100% correct. DRIVE IT HARD!!!!!!!!!! The car loves it. Seems like most the problems I have is when I'm in traffic or not pushing.
take care

Keep it up, Dingus!
Anyone here try these yet?

I haven't seen those break yet, but that is a possibility.
I have about 20+ pair out there now. Not a lot of reports back just yet.
I've been running them, but I'm biased.
Anyone??

Two of us were using these arms at the local races here last weekend. They worked great and neither of us broke an arm. These arms are a direct replcement for the original arms, they fit perfectly and look great. Thanks Dennis.
