I am currently working on my own design RG-65 hull. It has been named the ASKOOK. The name means "snake", in the Algonquin Indian language.

The fiberglass deck was eliminated and replaced with balsa. This  saved about 3 oz. off the hull weight. Current hulls minus the deck weigh 4-4.5 oz.

My latest build is a epoxy resin and fiberglass cloth hull. Found it too be easier to lay-up, takes less time, less supplies and clean-up time.

This is my second attempt at building an epoxy hull using the hand lay-up method. I don't have the equipment needed for vacuum bagging so, the end result was a pleasant suprise.

This epoxy hull weighs in at 3 oz., a nice weight savings over the polyester and fibergalss hulls. Also tried another method of building an epoxy hull. A technique R/C Airplane modelers use. Instead of using a heavy layer of Epoxy gelcoat or mix in an opaque resin colorant the mold has been prepped with PVA mold release. Then Krylon (new formula--enamel) spray paint was sprayed into the mold after the PVA has dried. After the paint had dried for a few days, the hull was layed-up. Let cure for another 4 days, then pulled the hull from the mold.
