Counter Rotating Props by reilly4 Sub-Lieutenant   Posted: 5 days ago
An excellent discussion with very valid arguments. I have always had my twin shaft/prop vessels with outward turning propellers, but I will now reverse one of them to inwards turning to see how much difference it makes. Always learning...

Counter Rotating Props by Trillium Commander   Posted: 6 days ago
Inwards or outwards - should the props be turning to meet together above the shaft or below it? Also from Wikipedia "Contra-rotating is where parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. Contra-rotating propellers should not be confused with counter-rotating propellers, a term which describes non-coaxial propellers on separate shafts; one turning clockwise and the other counter-clockwise." Torpedoes are a marine example of contra-rotating props. Roy

Battery problems by Dave M Fleet Admiral!   Posted: 9 days ago
Hi Allan You don't really need a pump with a fast boat as a simple scoop placed just behind the prop will give ample cooling water. Is it possible that your pump is becoming ineffective as the battery drains? Your prop was OK with the brushed motor because it was designed for this type of motor, brushless need much less coarse pitch propellers or very high capacity batteries and ESC's. Hope you can find a suitable set up Dave

Counter Rotating Props by Dave M Fleet Admiral!   Posted: 24 days ago
Actually for ships with props on separate prop shafts it's counter rotating. Contra refers to aircraft equipped with contra-rotating propellers with rotation about the same axis in opposite directions. Contra-rotating propellers should not be confused with counter-rotating propellers on separate shafts turning in opposite directions. I was intrigued by this discussion, possibly because it reminded me of my model flying days. What would we do without Wiki! Dave

Norstar Wave Princess by AllenA Seaman   Posted: 1 month ago
Built this Wave Princess 30 years ago meaning to use it with my children. Languished in attic since and now retired going to resurrect her for Grandchildren and would welcome any advice on motor size, prop shaft length, Propeller size etc etc. Picked up an as new MacGregor Digimac 111 transmitter receiver and servos at Boot Sale for £5, seems fitting I should use it for the old girl.

KuK TB IV by Dainesh Chief Petty Officer   Posted: 1 month ago
[Score: 10/10] - Comments: Kaiserlich und Königlich (KuK) TB IV Recently built scale model boat (1:50). It is a fine art work. Length: 884mm Beam: 95mm One 3 blade propeller. Main armament: 2 45cm torpedo tubes, 2 4.7cm/L44 Skoda rapid firer. Crew: 20 people Speed:27.5 knots In 1905 the Austrian Naval Technical Committee presented three different designs for a 110t coastal torpedo-boat, mainly differing in the propulsion system (VTE or turbines). Having insufficient experience with turbines, a final VTE-propelled design with oil-firing was presented in 1907. To compare it with foreign technology, Krupp, Schichau and Yarrow were asked for competitive designs, all of which turned out to be inferior. Initially STT was ordered to build 8 such boats, but this was reduced to 6, because Danubius had to participate. When the older torpedo-boats lost their names in 1910 in favour of arable numbers, these units became in consequence Tb 1-Tb 6. The boats were surprisingly seaworthy up to sea state 5-6, and during the war they saw active service on escort, minesweeping and anti-submarine dunes.

HMCS Sackville - WWII Corvette by gordc Petty Officer   Posted: 2 months ago
About 25 years ago I started building a Stuart Turner double 10 steam engine and soon after, I decided to build a boat to put it in. The photos show how far I've got. It's a model of a WWII corvette, HMCS Sackville. The original ship has been restored and is on display in Halifax, Nova Scotia. I've built it to a scale of 5/16" to the foot in order to have a displacement of roughly 40 pounds, which I figured I would need to accommodate the steam plant. It has an overall length is 65" and a 10" beam. The 5/16" scale also means that I have to make all the fittings for the boat from scratch. I'm working on the 4" gun right now. I had the hull in the water for the first time last September and discovered that the pitch of the propeller needed increasing and that the boiler couldn't make enough steam to keep the engine running at 600 rpm. The boat just sat there going nowhere. I've increased the propeller pitch and enlarged the burner orifice on the centre-flue boiler to increase the heat input, so I hope to do better this summer.
