Plastic blades might be worth a try. I think im gonna go ahead and use ceramic blades on this body. Im putting a proline hotrod body on my t-maxx 3.3. It was an easy fit i just had to make a new front bumper and longer mounts. Shortened the mody mount posts and used magnetic mounts to extend out to good places on the body and will use gorilla double stick tape to secure them. I swapped out the magnets with stronger earth magnets. Each mount haa a little over 8 pounds of holding pressure. Surely thats secure enough lol.
