Sea Queen aka MALLARD
I built it from a kit a few years back sold it then bought it back to do a refit & new paint job
MFA 850 torpedo Motor 3 blade brass prop it runs on a 12v Battery it is now with my nephews son in Northallerton

Built from a kitishack kit 56" it runs on two Hobby King 750kv brushless motors I used brake pipe to make the motor cooling coils two 200a water cooled esc,s, I got the 5mm shafts & 42mm brass props and couplings from SHG models the power is supplied via two 14.8v lipos this is a really powerful boat

built from a kit powered by twin brushless motors two 4c lipo batteries two 90a watercooled esc,s & twin brass props it runs a dream

Completed (nearly, still a few more crates needed) in July after a 2 year build on a Kingston Moldings hull. Not a scrap of plywood has been used, all made from Oak, Mahogany, Beech and brass. All fittings scratch built, boiler from Maccsteam in Macclesfield, engine TVR 1 A BB from Macclesfield model engineering supplies. Runs on 60/40 butane propane mix. Radio 3 channels used on Futaba 6EX 2.4 ghz set, 1 fo1 for fwd/reverse, I for steering.

Hi
I'll try and get it right this time. This is my granddaughters springer. 18x8 inch, 4 inch rudder, 540/1, 6v sla, with a35 three blade brass prop,she's only 4 so if you come to sail on our pond, give her plenty of room. The safety part of it ,is she has a 10mm flashing red led on the top. Sorry I dropped on my last post

Greetings from Hollywood, California. 😎 Many thanks to David Metcalf at Metcalf Moldings for his advice and for so graciously replacing parts I messed up. This craft has been swimming pool tested (after all we're in Hollywood) and it ran beautifully. Next stop is the local pond. I chose brass counter-rotating props. Those are lithium batteries tucked under the sides. I chose to recut the decks out of wood. Brits rave about plastic but I found it difficult to cut and forget about sanding down the edges. (I guess if you cut it properly you don't need to sand the edge.) Major mistake: watching a You Tube video that told me I should make brass joints using a Propane torch. it will make a good joint but it MELTS ALL THE OTHERS. There was a lot of learning here for me and thanks to David's fine kit I think I'm somewhat of a better model builder.

HI All, I had a request for infomation on the Motor and Gearbox setup that I have fitted into a Wavemaster, a Sea Commander, and Fireboat, all shown in various posts of mine. The gear boxes are fitted with a 2.92:1 reduction gear, and were purchased from Hong Kong on Ebay, this is the information if I can publish it in this post. I mount the gearbox this way up to position the motor in the boats as low as possible.

This model was scratch built from US Coast Guard plans. The boat is constructed of balsa wood and the hull coated with fiberglass resin. All the deck gear is scratchbuilt from brass, the propellers, led's and figures are the only commercial parts. Scaled at 3/4=1 foot the model measures 42 inches in length.
It's powered by a Pittman 12 volt motor and controlled by a 4 channel radio. Working features are running and spot light, siren with flashing blue light, sweeping radar antenna and deck lights. Built in 1985 the model the lifeboat is accurate in appearence for that time period.(The prototype has been modified since).
The actual lifeboat is attached the the Coast Guard's Motor Lifeboat School at Cape Disappointment and is one of four boats of this class.

Two Reclaimed Ebay boats, both running same setup Johnson 600 with 2.5:1 reduction Gear Boxes 45mm Brass props and 7.2Volt NiMh power.

HI This is a Celia, I think, it was a caldercraft kit but am not sure. it is running on a 545 motor at either 6volt or 7.2volt with a 35mm 3blade brass prop. its performance is about right for the scale and type of boat. it sails at the Lake used by the Cwmbran Club. I bought it last year at the Shepton Mallet Show.

I have had this boat for about 5 years, so thought that it would like a day out. Sailing at Cwmbran August 2012. its a Billing Polar Trawler, not now made but at about 32 inch long is a managable size. Twin 385 motors 35mm 3 blade brass props. and running on a 7.2 volt 3700 mAh NiMh viper speed controller and a 2.4 Ghz RC it will potter around all morning on one battery. I originally ran it on a 6Volt 4Ah Gel Cell and 27 Mhz setup.

Photo taken at Portishead on 1st July by a friend in my club many thanks to Les Masterton for allowing me to add to my album. Model running on a Johnson 600 with 3:1 reduction gearbox 45mm 3 Blade brass prop and 11.1 Volt Lipo. Not bad for a model designed in 1952. 😊
