Hi Nutrunner, It's a great little tug, good response from the kort nozzle! I built one over 30 yrs ago! Good memories! I used a 7.2 volt NiCad back then. It ran for hours on one battery!

Propulsion Hegi Revell Fairplay V tug model by RNinMunich Fleet Admiral!   Posted: 9 months ago
Hi, I can't profess to be a Tug expert but I believe the general rule is 'Low revs & Hi Torque'. I hope one of the tug fans here will pick up this thread. Also this forum might be useful to you; a discussion on kort nozzles & tugs 'Fixed or steerable'. https://www.rcgroups.com/forums/showthread.php?1536288-Steer... Good luck, let us know how it goes. Cheers Doug 😎

Propulsion Hegi Revell Fairplay V tug model by Radiosailor Sub-Lieutenant   Posted: 9 months ago
I recently bought a on Ebay 'stranded' vintage harbourtug which will be fully rebuild. (I actually bought a NOS hull, and old - but good build - superstructure and all the deckgear & fittings. Except for some essential parts... There's no kortnozzle/rudder and propellor. I would like to know what size of nozzle and propdiameter I should mount. Originally it was designed with a steering nozzle/rudder, but the only item which comes close is the fixed nozzle as used on the Robbe Happy Hunter salvage tug model.(which has twin nozzles) That nozzle would be fixed with a seperate rudder for steering. What would you advise? What alternatives are available? (Making a proper nozzle myself which actually works and looks to scale is out of the question.) Attached three photos: one showing original (steering nozzle) and teh other with this Happy Hunter fixed nozzle, and te drawing showing the design.

Alan you are right they are from another thread this was just a quick option I will try & get the trawler out later it is up in the garage loft & take some pictures for you, as I remember the motor was amidships to allow room for a 12v battery the servo horn is straight to the kort nozzle rudder arm pleased to help if I can Bob 👍

smitt rotterdam by Dave M Fleet Admiral!   Posted: 4 years ago
HI Barry & Mark Yes lack of knowledge of a particular model can make advice difficult. I have fitted kort nozzels to a couple of my tugs and I would advise using a template to ensure you get the nozzles absolutely central with the prop shaft. The Instructions with my Al Khubar suggested using a plasticard disk cut to the Inner diameter of the nozzle with a hole drilled In the centre to take the prop shaft (both need to be a tight fit). You can then attach the disc to the prop shaft and fix with nuts either side of the disc and align the propshaft to the nozzle. Try and make sure you get everything nice and square as the props should be a close fit, mine had a 1-2mm clearance all round. You may find that the hole In the hull needs to be widened to get the required result, mine certainly did, but you can use plastic padding to make good once finished. If I was doing another I think I would also test fit the motor to make sure of a nice straight drive chain. My Eldergarth had steerable nozzles so alignment Is more critical than for a fixed nozzle with rudder. Hopefully your plan shows the position of the prop relative to the rear of the nozzle as some props have an extension on the boss that might foul the rudder, I know from experience with my Al Khubar so I suggest you try your prop In position before you finally fix. Hope this will help Barry fit the Korts succesfully. Dave

Jervis Titan Tug model with a job by PikaSteve Petty Officer   Posted: 4 years ago
Hello all. This Is a scratch built boat from a fiberglass bare hull that I purchased. The purpose of this build Is to give me a toy to play with at my cabin at Langdale BC. This Is on the ocean and many log tows go past here so there Is a scandalous amount of logs In the water that we burn as firewood on beach patio and our fireplace. The tug will be used to push these back to shore where I can reach them with a pipe pole, and hoist them up with my crane. The boat will be very crude In Its finishing, and have very little detail, and the "house" will only roughly represent the tug I am modelling It after. In fact I expect to place a handle on It so I can handle It like a suitcase. It Is 45" long and single screw (3.75" four blade prop) I am using a steerable Kort nozzle I built and has a rudder on the nozzle as well.
