Last night, I cut the mast for the Vinta and this morning screwed it on. The mast solid wood but very light. It will be wedged between two dividers or bulkheads in boat language. It will be removable for ease of transport. Not final paint yet.

Hi modelers!
Created this blog to display my boats. I carved my first boat from a log when I was 12 years in Zamboanga City down South in 1962. I made it by hand using hammer and chisel. This is a design from an American book, circa 1935 titled Boats, Kites, and Airplanes. I powered this boat with rubber bands, electrics, and glow engines. The log was sourced from native farmers from a place called Ayala and the spec was that it won't crack and light too. Till now, the boat is intact. Pictures to follow. I never made the deck for this boat but has taken it with me where ever I moved. I now live in Metro Manila, 67, married, one child, still consulting in my professional field, investment banking and financial analysis. I bought toy boats then, one I remember had a friction motor. I pulled a string and it sped away in a pool. I lived in HongKong half a year in 1968 training in credit with the Chase Manhattan Bank. Bought several plastic toy boats, electric, of which one was RC. Still have them and I reversed engineered the RC system. Fell in love with model planes and set boats aside for a while.
Somebody gave me a 28" PT109 obviously made from a kit using balsa wood. Still have it but it is brittle now. Am making a mold from it for GRP (fiberglass). Decided to enlarge it and made a mold (plug) for a 42" PT109, still in process today (for decking). In the meantime, I had a dozen "Fisherman's Sports boat" made with Fiberglass.
ABOUT TORPEDO BOATS
Torpedo boats should run fast and hydroplane. That is what they are known for. The real PT 109 was 80 feet and had 3 propellers each driven by a 1500 HP engines. Top speed was 40 knots. The PT 109 became a legend because JFK skippered this boat in the Solomons which was split in halves by a Japanese destroyer in WW2. The other famous fast PT boat was the British Vospers, later used by Malaysia. The best motor to use for this boat is the brushless type using Ly-Poly batteries.
THE FISHERMAN'S SPORT BOAT
My models are 32" long and it looked like a fishing boats. The hull though can be used for other deck designs. Regular silver motors from size 390 to 550 can be used in this boat. Motors for RC cars using brushed motor will be fine. The advantage of using brushed type motors includes cheaper and more sturdy batteries (Nicads and Metal Hydrides). Chargers are cheaper. Of course brushless motors is an option.
SAILBOATS
Have one sailboat RC. It is being reconditioned. Last December, went home South to attend a HS reunion and decided to build memories. I constructed "Vintas", still models and RC as well. In process.
NEW MATERIALS FOR BUILDING BOATS
Short of fiberglass and carved model boats, balsa sheets because popular in building models boats. Plywood too. There is a new material used in signages known as Sintra boards.Started experimenting and it is very promising. Cyano glue holds it well. It is made of PVC and thus water proof. Will be building and posting model boats using Sintra boards.
RC SYSTEM
Plenty in the market today using 2.4 Gigahert and Spread Spectrum, meaning no need for frquency conrol when there are others with radios around. . Servos are also common items today. old AM radios can be used.
SHAFTING AND PROPS
The best so far I have seen in the market is the "TFL" integrated drive system. A bit expensive over U.S. $125. Just bolt it on and it is ready with a motor mount and prop. The flexi shaft is sealed too. Old type steel tube shafts are still available but not recommended for fast boats anymore. Grease is still used in the tube to prevent water seeping into the hull. I developed my own water sealed shaft belt driven. Cuts down on vibration.
The three existing hulls I have:
Left is the original 28" balsa PT109, Middle is the Fisherman' s Sports Boat, and right is the 42" PT109 hull.
The one meter "Vinta" hull which will have outriggers and a colorful sail. RC.
Propeller shafts.
Grease is used to stuff the shaft housing to both lubricate it and seal off water from going up the shaft.
The newer and better type of propeller shafting called the Integrated Drive System. Note the square flange which goes to the transom of the model boat. The shaft flexes at this junction to allow adjustments to both the motor and the propeller vector.
Belt driven. Less vibes.
