if what you say about the metal bending and than loosing it's stringth after it is hammered stright
mine should be like a wet noodle.
it has ben been bent five times and hammered stright five times.
there is some real poor engineering behind this setup on the hell fireHPI should have thought this over and used a better setup than a floating brace and plastic pieces to hold the pins inplace.the braces front and back should have been bolted to the main chassey and there should be two long pins with nuts and washers to hold the a arms on with.
After the first deformation whatever strenght was in the part was lost and the reason you've had to fix it 5 times is because it has lost whatever strength it had. It'll bend back into shape but will always be primed to bend again when enough stress is applied. The 'wet noodle' example doesn't fit this is material dynamics. and no, I'm no know it all, it just I've bent, re-bent and broken enough rc parts through the years to have an insight. Anyone who has bent an alloy a-arm or tougher still, a trunbuckle will know what I'm on about. It will bend again and it doesn't take the same amount of force that caused the first bend.
It can be argued that the set-up is flawed and what HPI should have done but there's not that much different from HPI's set-up than what you would see on a Xray XB8.
