X6 Squared Rear arms - Breaking/Cracking

[X - Racer]

Has anyone had a problem with they rear susp arms part No 3012 breaking or even cracking after a minor tumble whilst racing?
Last weekend I managed to break 3 rear arms in one meeting!! they broke after landing from small jumps.
I understand that the arms are only available in graphite. They seem very brittle, maybe plastic is the way to go?

Not had any issues with them at all to be honest, it is one of our least sold spare parts (and outside of wing mounts and hinge pins there are very few that are "frequent" sellers)

How cold is it there?

I had a similar problem last winter - I broke 2-3 over the course of the winter and put it down to the cold. I tried boiling the parts to see if it improved the situation but not convinced it made much difference. I broke one late last year following a massive off whilst racing indoors (6 ft high table top collision ) but I ran the whole spring/summer/autumn without issue. The indoor racing was in an unheated facility so was very cold again, maybe 2-3 degrees!!

Doesn't really help you very much but I can sympathise with your plight...throughout the summer is was mega strong and reliable.

I've only ever broken 2 rear arms in nearly 4 years of racing the x6, and one of them was on on the x6 non squared... They were big crashes too, so fully expected to see damage! Cant say I've noticed any cracking in the cold weather either?
Maybe you have just been unlucky with some awkward tumbles?

Perhaps...

I wonder if adding o-rings on the shock shafts to help cushion the uptravel might help, as it could be breaking when the shock is fully compressed but the wheel still wants to move upwards and the wishbone is weaker than the other parts so just cracks?

done a fair few, seem a side swipe splitas the outer pin mounts i have modded mine to take a bolt as a rally x car does and fitted drill blanks for hinge pins, now bullet proof, will post a pic later
