Thank you Larry, There are no plans for this hull it is my own design, I prefer to work with demensions and measurements however some builders are scaling the Dunlap 1/10 and 1/4 Crackerbox plans to get a 1/6 build, they are scaling up or down accordingly to get a hull in the 28-32 inch range. On this build I will be using a flex cable subsurface driveline with an under the hull strut. But a solid shaft would work well also. See post #158 and 159 for the set up I'll be using. We have an agreement for the FE Nats to run either a under hull straight shaft of a flex line that need be under the hull but allows the prop to extend past the transome a bit. We'll be running these set ups for some exhibition races at the Nats. But builders who have no desire to race can build it to their choice. Also there is a fiberglass hull that will be out soon as well as a short kit that will be out soon (If interested get with Flyguy55 on the forum) , And a full build very detailed kit from Legend Boats. I have finished the hull and will be installing the running gear and testing shortly. Here are some pics of the hull ready for final install. I'll post more in coming days. I modified some pilot bust for drivers as none are available that I can find in this size,Comment

Wel,I took the first step today,ordered the wood from National Balsa,about 50 mi from me. I will be modifying a Dumas SK into a C box, if I square up the sides it looks like a C box, almost flat on the bottom,L and W are good, wil add 2-3 in to length. The SK 2 is 27 in,want to end up with 29-30 in. WHAT do you think?? LarryAmerica home of the free, thanks to the brave [/url]Comment

Finished
I spent most of Saturday finishing the Crackerbox, To get her redy for a test run, the first thing I did was to add the fotation, I used swimming pool noodle cut in to 6 inch sections and stuffed the cavities of the nose with it, Next I added bunks on the bulkheads near the floor in order to hold the batteries secure and increase COG adjustment, I also added a stand or shelf for the ESC. I waterproofed the bunks and shelf and moved on to the cooling pick up which I installed through the floor near the transome. Next I installed the Blackjack motor and strut. I sealed the adjustable strut where it enters the hull with some white caulk and let dry. Once dry I added the .130 drive cable, motor coupler and teflon tube then used shrink tube to help keep water out. I am using an SV-27 esc I had on hand which works well with the BJ motor and is smaller then the proboat esc. I then added a set of trim tabs I had built from aluminum angle and installed the rudder and steering servo assembly. Now the receiver and test, Everything went well and worked out for the bench test. I decided to add an antenna tube to the cockpit behind the mechanic that can be removed when not running but allows the receiver wire to be raised when in use. It looks like I'm ready for a test run today. Here are the photos of the lay ouy and hardware all ready to go.

Well the test did not happen, as mother nature did not cooperate.
The pond that was open now has about a 10 foot ring of ice around it. It has been warm here during the day but pretty cold at night, Forercast is for warm days this week if the pond opens back up I'm ready.

Thats funny, I thought about the same thing The SK is very close to a CB, I think your plan may work fine, Have fun with it. Thats the main idea. Keep us posted as to how it works out.
