    Graupner Arrow conversion.

    Heres a couple pics of my arrow conversion from the graupner/steerable outdrive to a 800 with hughey hardware. This was a e-bay purchase as well, it looks like whoever painted it was in kindergarten, lol, so bare with the cosmetics as well as my sloppy building. :D

        Started on some of the reinforcment today, I prefer carbon fiber strips the airplane builders use, its fairly cheap (two 3ft strips for $6) and easy to work with, I cut mine with snips and ca them in. The boat is already incredibly stronger, once the cross pieces are tied in, it will be a sherman tank like my EV, at least thats the plan.

            Steering servo/linkage installed, boxed off where tube enters hull and epoxied, decided to section off stern from rest of hull, tired of chasing water around in the bow. Also cut notches in motor can so that I can advance timing if needed.

              Looking good. Way to keep costs down. I need to take a page from your book there. I tend to get lazy and buy things I can make. Cant wait to see this thing run. How much longer you thing before it hit the water?

                I wouldnt do it this way with a nicer boat, But in this case I sold the graupner hydrodrive for more than I paid for the whole thing lol. as far as first launch sometime next week, out of CA, Im paralized without it

                  LOL take away my Devcon and I'm powerless also:D. This build has inspired me to go back to my first boat. I am thinking of finding a Kyosho jet stream 800. It's the boat that started it all for me about 10 years ago.

                    Love the innovative hardware! How is the motor held in?

                        The motor will be held in place with the cross piece, the prop is a X646/3. Ed Hughey sent it to me, I must admit it looks proud back there. lol.

                            Excuse the pics Ive been sailing with the captain!
                            At this point deck is attached to hull, this turned out to be quite a treat as the hull had contracted with all the CA usage, it needed to spread back about 3/4" to line up with the deck. Two people and a few layers of skin loss from the zip kicker and its on :D also ran some velcro down the center to hold the 12 cells, trying to keep the weight low and centered at this point. Believe it or not the boat is really close to a 30% cog from the stern. The last real obstacle is finish filling the area where the downward stern tube section was cut from the hull. Its all gravy from here!

                              nice build, looks like you did a lot of work to cut out the bottom of the hull...looks like it might need a bit of sanding out though..
