Reinforcing weak parts for the D4?

[Edd]

Hi,

I've been racing with my Cyclone D4 and I have found that the weakest part is the suspension arms

Everytime they snap where they meet the hinge pins I want to reinforce them some how so I can save on parts.

There is a diy store not far from me and I reckon glass fibre could do the trick. I've seen people putting some one their wheel wells but not in large amounts as I intend. I don't think the glass fibre would weigh much and I've used it a lot making boats so i don't mind the weird feeling.

any help would be appreciated
