Hi

has anyone had any issues with dog bones breaking on the T4'14? I've broken a rear one and two ecs dog bones (in consecutive races!) all under power i.e. not as a result of a crash.

I've had a T3 and 2 T4's before and never had an issue.

Just out of interest what surface, motor and tyre combination?

Have you used the grub screws and put them in too tight?

This could bend the pins slightly and stress them which can cause them to break very easily.
If this is the case try using heatshrink instead of the grub screws;



I've used this on all my ECS style driveshafts and have never had a failure, just a few bent dogbones

Cheers D but that's not it. They are breaking above the pin. It's where the dog bone meets the trinnion.
