Hi, Have added two brushless motors prop shafts etc, twin rudders as per original boat and also a cabin roof. Did a test run (sorry no pics) but she was great, predictable and stable in rough conditions. I have started on the inner decking, this plugs in the hull, still a lot to do.
Started on Superstructure, as I had some free time, the cabin and sides will not be removeable and access to installation will be via the rear of cabin's floor area. lite ply profiles cut to an old Vic Smeed design.
They are a great looking craft, I am restoring one myself, please be aware that red paint may contain lead, so wear a mask while sanding. My restoration is of a old Fibre glass hull I intend to install twin rudders and motor shafts and go brushless, I am building the superstructure from scratch with some help from old plans. I want to have a swordsman type cabin.
Hi thanks for your input The pictures do not show the mini fans now attached to each motor which were robbed from PC cooling fans. The boat is not a performance craft I will hopefully only pull 20 to 30A from each of the low kv motors. Spec. 2808 1400KV 14 Poles Brushless Motor Max Watt: 350W Voltage range: 7-15V Max amps: 35A No load: 1.2A
This Boat is a bit experimental the main goals where for it to be light in weight, and also a more correct hull shape, also to keep cost to a minimum and as scale as practically possible. To answer the question about not using one single skin, is that ply will not bend in two directions, the sides of the hull have curves to them, the length of the hull is also curved, especially the bow but also curves to a narrower stern/ transom. The best way to skin the boat is by 60 degree planking in two alternating layers but this would make the hull too heavy for me to transport, due to back problems.
Some pictures of the original sails and rigging, to my surprise the carbon fibre mast was in two sections, there is no mention of this in any manual or information regarding this boat. It could be a replacement (Perhaps a fishing rod!).
Ok start by removing all I can from the hull, rudder, mast, stickers, stays. etc a) Sand down the hull and wash with white spirit. b) Fill scratches and re-sand. c) Reinforce mast position surrounding area.
I have by luck, not judgement acquired a second hand 'Nirvana' Yacht, it is a sloop rigged craft that was only sold in America and retailed between $250 and $350 according to the revision version and the year brought. This was a bit of a surprise to me as I only paid £10 for it. The Nirvana RC Sailboat was first produced by Megatech in 2002. and is 32in long and the hull& deck are ABS plastic. The quality of the boat is unmatched in the price range, with such features as a lead keel ballast, superior polyester sails that won't mildew, stretch or tear, and fittings that make the boat a dream to sail. The mast and booms are made of carbon reinforced composite that is light and very strong. The Boat hull is in sound condition just a few scratches, there is a hairline crack in the mast area, no radio gear at all. and sails are usable but really need replacing.
Installed the three out-runner motors, I hope I never have to replace them. They have rubber mounting washers and nylock nuts and spring washers in M3. They are about half inch apart took a few hours to install with full access as currently boat has not been skinned. I hope to add small fans to the prop hubs to keep them cool Now have received the rudders and water scoops. they will be installed after the bottom skins are on.
Hi Please be careful with copper/brass alloy propellers as they often contain beryllium which is is highly toxic, read about the dangers and take the appropriate safety precautions. Before you work on these propellers, such as balancing, sanding, polishing or repairing.

Pictures Rubbing down hull, Close ups of hull repairs Drill holes in transom for the exhaust pipes (water cooling outlets). Added spray rail to side of hull. Have found that I am having bad reactions to the fumes from Gorilla Glue.
Thanks to ChrisF I am able to rebuild the boat with a different superstructure, but using the Huntsman 31 hull, he informed me of a Sport version of the 31 that had similar cabin as the 28. With some investigation. The New boat will now be '2017 Huntsman 31 Cockpit', this is a modern remake of the original design by a new setup. https://www.faireymarine.com/new-boat-showrooms/huntsman/201...

The boat was free but I gave a small donation to the club,(Darlington & District Model Boat Club). Started by removing all hardware, motor mounts, prop shaft, rudder, water-scoops and outlets. Next fill the holes I have made, remove some excess wood. roughly sand down hull. Foam bow area, and glue crack in deck. Find a lot of damage to the fibreglass hull, large chips out of the gel coat and associated stress fractures, and other spider web cracks. Drimmel all crack lines and open up chips and dents, then fill with a filler. an experimental mix of P38 and Araldite, hope it works. Start planning drive options I have a number of items that I have brought and not used that will be put in this boat, otherwise they may never find a home. last picture shows drive option to use up components.
