Getting closer to end






Recycled my old 48" AC class RC boat as it sailed poorly with homemade sails. Used ballast, sail arm servo, tangs from mast and gooseneck. Used tanks to do the jib tack leads and installed the jib sheet leads. Got fore and aft deck birch ply 1/32 and 1'64th inch for fore and afte deck respectively. Trial pained the stern with a cobalt blue metalic finish. Will fade it from back to front from blue to white. Ordering remaining fittings and would be sailing in less than a day once these and sails arrive.

Mast box set





Here is second to last step before decking goes on. All is needed it to add balsa to inside of gunwales for deck to be installed and glued on, add mast ram, and install recessed pot for receiver and batteries. Still need to order rigging and sails. Will be using very thin marine ply like 1/32" or 1/64" for deck and cut outs for access holes for mainsheet post, rudder, rudder servo, sheeting servo and mast box.

Sail servo and final bulkheads installed






See how servo is angled to keep it under deck. Will be using a sail arm servo for sheeting. Did a dry run with it before adding deck. Dead ended to fore bulkhead with arm pointed right back to the bulkhead. Single turning block will go on end of arm, approx. 85 mm from center. Control sheet will run through bulkhead and just above deck to turning block at stern then to mainsheet post. When fully sheeted in, will tie jib sheet right to control line at the back block. The control line will be the mainsheet. May add some elastic from the mainsheet post run to the point where both sheets attach to avoid a birds nest below.

Sail arm moves forward to sheet in. Without fine trim, I have 12 inches of travel. Probably a bit too much, but will install a stop point on transmitter knob, i.e. balsa glued to it, if it is too much. Got to order sails, rig , paint, lead ballast and then will likely be ready to sail. So far, seems very light. Yet to weigh it, but I am sure it is under where it should be.

more pics of keel box and, rudder post and mast box




Mainsheet post





Put mainsheet post in today. Under it is a small block of 1/8" ply epoxied to hull for support. Placed the post on it and mixed up a hot batch of peanut butter consistency epoxy with 407 filler(ran out of 410), centered it and let sit overnight. Today I built the brace that you see supporting it to support the deck. Decided on a flat deck. Easier, lighter, and quicker to build.

You can also see the rudder post and brace epoxied in and the rudder servo dry fitted and ready to epoxy.

Note the stern... I cut the original station down to about 1/2" from the hull when planning on doing a skiff deck. No skiff deck planned now, so I added another stern section and will do a cross member on top flush with original station that was cut down. AS a result, the middle portion will be recessed and look pretty neat. Now have a few options to be creative now. Till the next post.
