CAT SX2 Steering arms

[shawn]

Hi.
My Cat SX2 snagged the rope today and the RH Steering arm snapped. (U3590)
Is this a common part to break?

Having not owned one before I have noticed the Cat SX has alloy versions so I'm considering replacing my plastic arms with those. Are they any stronger?

The last question is; what servo savers fit this car? There doesn't seem to be much space between the servo and the undertray to make it possible ?

Thanks.
