    Repair a cracked hull

    My cheetah cracked down the seam on the right hand side all the way through. I plan on repairing it, but I need a little help on how to go about it.

    It would help us to help you if you added a few pictures of the crack. Not all cracks are the same.

      Is the boat Fibreglass or CF ? Like Jesse said, a pic would help.
      My CF Fantasm(Zonda) did the same a couple years back. It’s a chore either way but not expensive just takes time.

            You could glue it back together with fiberglass resin . Run a strip an inch or so of fiber glass on the inside . Shouldn't be to bad just aggravating.

                I would add some ground fiberglass into the resin for added strength AND do the fiberglass cloth backing on the inside. I also wipe the cracked surfaces with a clean rag with acetone on it. The acetone will gummy up the surface and make it more acceptable to the new resin. Good luck and pics of the repair would be great

                  Once you glue it back together, you should have enough oozed out to block sand down so no filler should be needed.

                          I fixed this (photos are half-way into the repair). Send me a PM and I'll get you a copy of Hanle's Primmer for Repairing Fiberglass Aircraft. Most of it can be easily transmuted to fiberglass RC boats.

                              Man what a job. Kudos.

                              I'm certain that was a frustrating experience at the time, so don't take this the wrong way, but, the photo of the boat with the branch through it is hilarious.
