Being the novice at this traxxas Blast, I dinged both ends of the prop. Took out good chunks, really effected speed and overall performance. I need to replace it but have no idea how. Is this difficult? I'm mechanically inclined but want some input. I can't see how to take prop off so I think shaft needs to be replaced too. I have no idea. Further, is it recommended to switch to an aluminum prop? If so, what size and make. I really want to keep my blast stock, problem free. Thanks.

Ps. How do I attach photos or vids from my iPhone?
