What do you know about casting materials?

[redhatman]

I've been thinking for a while now of making prototypes out of something like clay, forming a mold of it, and then pouring some sort of casting material into it.

I went to Michaels Arts and Crafts Store and the lady didnt know anything, she answered 0/4 questions. I would want something that is cheap, yet strong for rc abuse (tough and flexible).

I found some "Insta-Mold" which is $9 for 12 ounces. It is supposedly a flexible mold material that works with resin and plaster without release agent. I looked at some Casting resin, its around $20 for a decent amount.

On HPI's website, it says the X cage is made of nylon. Any information on this?

Please let me know of any ideas you may have, whether its how to go about this, what material to use for casting, or feedback on if Casting resin would work? Let me know, again, any help is much appreciated.

The nylon is a thermoplastic and is injection molded to form parts, that is, it is heated to a semi liquid state and injected under high pressure in a mold then cooled to form a part. Not something you could do at home. Click FastEddy's link above, lots of good stuff there.
