Layout and Limitations by NPJ Commander   Posted: 5 days ago
Layout and Limitations Although I am really quite desperate to get on and put a few bits in, it did strike me that before I mess the current systems up on the Tug, maybe I should find out how they work. So although I am leaving the Bridge/Wheelhouse until after the Hull layout is resolved, I need to check out what connections are made to what before I detach it from the Hull. So having a look in you see a busy circuit board and a plastic bottle! Pic 12 -16 What is needed is to determine which leads activate which features before I start chopping leads to separate Hull from Bridge. To this end I attached the standard battery and fired up the Tranny. I reconnected the leads that I had unplugged and switched the boat switch to on. Pic 17/18 Action of motors, lights in three sets and ‘smoker’ cables were identified, but I have not found the ‘horn’ yet. So that established what leads went to what and also raised the question for the future ‘what can be used later’. I noted that some cabling groups and routes from Hull to Bridge where given the ‘silicon treatment’ which I intend to reinstate before replacing the Deck. Having established how the setup works and what can possibly be retained, I removed the ‘standard’ battery, unplugged it all again and loaded potential ‘extras’ into the Hull to see how it would sit in the water. Now I can separate the Hull from the Bridge completely which enables me to have a good look at potential layout and consider weight and its distribution. I did in the early days mark the waterline as it was with standard equipment and also the CoG point fore/aft, for later comparisons. Forgot about Lateral but I assume centre line....................... Maybe pointless, but I made a drawing of the Hull and also laid out some of the components that may be used in the Hull itself. Pics 14/15. Currently the weight of these ‘extras’ amounts to 562 grams 19.8 ozs, from which must be deducted the ‘standard’ battery weight 104 grams 3.6 ozs, when considering real differences, so 458 grams, 16.2 ozs and still below waterline So I now have all these bits, the boat in three pieces and I am considering putting up a banner in the garage which would read... All the gear and no idea! Next move will be trial runs on the new motor control set up and checking out the sound system using the Transducers. NPJ

Aero Kit - Sea Queen by appstore Seaman   Posted: 8 days ago
I purchased and built this kit, did not have any problems but found the supplied brushed motor was inadequate for the performance I required. So installed an overlander T4250 brushless motor with a 45mm prop. changed the battery for an overlander Lipo 4500 mA battery, fusion Hawk 60amp ESC. totally different boat as to the performance. Slight modification to the motor mount was required.

Motor installation by GARTH Commander   Posted: 9 days ago
I had some 12 volt motor out of Black & Decker drills so I will use one I find that if motor isn't installed early it becomes very difficult to mount motors in a completed hull .Line up to shaft & couplings . the other thing is I us a Graupner flex coupling . They work great only problem they are no long available any where .

Hobby Engine Richardson Upgrade by octman Captain   Posted: 19 days ago
I have an old Southampton , off E.Bay a couple of years ago. I fitted the Components shop mixer, 2x 3400mAH NiMh packs(one for each motor)2 Mtroniks 15A Marine vipers, Technobots diesel sound system and also a Technobots 16 channel sound system. There is not a lot of spare space! I had a problem with the mixer eventually. It worked very well, as I did not think the turning circle in the original form was very good. I took it out eventually and went over to tank steering, which is OK but seems to be more effective in turning one way rather than the other, it's fine in a straight line. I found out after I had removed the mixer that the supposed problem was of my own making. So many wires inside that I was not in fact charging one of the battery packs so it ended up flat. Nothing wrong with the mixer at all! I mounted the engine sound speaker in the lower half of the cabin,where there was just enough room, where the window openings are not glazed(at least on my boat they aren't). Sound was OK but it was a bit lacking in volume, but I may need a higher power speaker, not sure as audio is a non area to me. The 16 channel unit is good in that a micro SD card is supplied with pre- recorded sounds, and instructions are given on how to record your own. The difficulty with this particular sound system is finding somewhere to put the second speaker as the 2 systems cannot be fed into the same speaker. It was a bit faint to say the least,possibly due to the tiny speaker I used. I tried to fit a transducer glued to the underside of the deck but there was no improvement so that is a work in progress. The inside of the hull resembled a very untidy birds nest! CHris

Deck in! by Skydive130 Lieutenant   Posted: 21 days ago
After a week away in Lanzarote, have had a couple of days to get some work done. Left side of hull is now fully sheeted, gaps filled and awaiting final sanding and glass clothing. Decided to get ahead of myself and have fitted all the deck pieces and the cabin deck formers. The inside of the hull has had a second coat of epoxy resin and will get a couple of coats of yaht varnish once the final pieces of internal wood parts have been fitted to include battery tray, motor mounts, prop shafts, servo rail, ESC tray, receiver tray, speaker/engine sound module tray. Up at the bow have fitted the wood for the on/off switch, sanded, sealed and primed the bow deck before adding a couple of the detail parts.

St. Albans model show. by robbob Fleet Admiral!   Posted: 21 days ago
I’m pleased to report that the fireboat finally got it’s bottom wet at the St. Albans model exhibition last weekend. Sadly it was only in the very small temporary pond that the club set up for the ‘have a go’ boats during the ‘free sailing’ session at the end of the second day, nevertheless it was a good ‘tank test’ for the motor and systems. The boat gets up onto a plane immediately and crossed the water into the hands of a ‘catcher’ on the opposite corner in seconds and when held static under full throttle it’s quite a job to counter the thrust. She sits nicely on the waterline but needs a small amount of ballast to correct a very small list to port, and I also need to extend the rudder servo limits to reduce the turning circle a bit. It’s a shame that there was no one to hand to take some action pictures and video so I only have a few static shots that I took. The St. Albans model show was itself a phenomenal success with public attendances breaking all records over last year and was well supported by numerous other clubs and societies. The glorious weather on both days also helped too! If you attended the show I hope you had as much fun as I did 😁 It was also great to chat with other modellers who inspected my boat in the clubs display room at the show, many of whom have also made this model or have one under construction, it's was a pleasure meeting you all. Robbob.

34" Precedent Huntsman by Novagsi0 Lieutenant   Posted: 26 days ago
Hello all, been making great progress paint wise, and fitting out the huntsman. A popular DIY store paint came out the exact colour (Oxford Blue) I was look for. Radio control and motor mount nearly done just need to decide on the battery and wait for a nice day.

Crash Tender Shaft Tube Poistion by neilmc Commander   Posted: 27 days ago
Sometimes I hate work it gets in the way but I've managed to get the first fix for the prop tube at last now to leave for a while as work and courses in the way again. I have also managed to open the hole for rudder guide and presume this needs a bit of expoxy resin to secure it in place? The oiler is also fitted and a bit of cleaning of the inner hull to remove some of the old paint ready for sanding sealer coat after I've mounted and aligned the motor - not looking forward to that at all if past experience is anything to go by. But now the old mount is out there is more space and the prop and shaft is at a much better angle thanks to Dave and Doug😁😁

34" Precedent Huntsman by Novagsi0 Lieutenant   Posted: 1 month ago
Some good progress made the weekend with a paint brush and the motor mount started, some holes for the motor to breath and the end plate machining now required. Also some details added to the top whilst other items were drying.

Crash Tender Shaft Tube Poistion by neilmc Commander   Posted: 1 month ago
Standard Saturday Mrs Mac decided I had other things to do before being allowed out to play but I think I've got there, just need to check it's right before gluing up. OK so I lied that I wouldn't be asking more questions on this topic😁😁 The hole has been opened out enough to achieve 3/4" but the photo doesn't really show it. It took some time to achieve it as well more time than I thought, even used my dremel at one point😁. But pmdevlin's tip on using a disc was a great help. The position of the outer tube on the hull needs a slight adjustment but nothing major and still achievable as no glue. I did have a check fit of the motor and came across another issue as there was no way I could achieve alignment of the shaft and motor which was made easier by Doug's universal coupling idea😁. I went for removing the last remaining piece of the old motor mount (should have listened to Dave a year ago) which took about an hour as it was glued in good and proper.😤😤😤😤😤 There is some clearance on the hull from the prop so think I'll be going for a 30mm prop as suggested by Dave as to my surprise mine is 40mm diameter. Hopefully the arrangement is all good and I can use Dave's and Doug's tips on getting it secured. I still need to blank off the water pick up and fit the new rudder tube. Also I think the motor alignment will still be interesting as after removing the last bit of the old mount the motor was interfering with the bulkhead behind it so removed so it. Also will possibly need to take some out of the hull centre piece to achieve a perfect alignment. Hopefully tomorrow will go well as will also fitting the oiler as seen on Robbob's Build Blog.

Crash Tender Shaft Tube Poistion by RNinMunich Fleet Admiral!   Posted: 2 months ago
Agree 👍 The longer shaft is an advantage cos it provides more flexibility and 'wiggle room' inside the hull for the motor mounting. One thing puzzles me! "Skeg hole"? Do you mean the water scoop hole? I always understood that the skeg is the extension of the keel intended to protect the screw and rudder, and in many cases is a metal extension of the keel to support the bottom end of the rudder shaft! See attached examples of rudder skegs; Billing Fish Cutter (an inherited restoration project!), Southampton tug, U25. Neil; what you referred to as 'the skeg' is generally known as an 'A bracket' or 'Bearing bracket'. It's purpose is to support the final shaft bearing just before the prop. On full size ships the shaft tube does not extend all the way back to the prop. It stops at the hull exit and the 'A' bracket supports the final bearing at the end of the actual drive shaft. See final pic showing the stbd. outer shaft of my HMS Belfast cruiser. (About to be fitted with new brass Raboesch props!) If I were you I would not even try to bend the bracket again, and would not screw it onto the hull as it was. This is a double violation of the hull integrity and will eventually cause water to creep into the wood and start it rotting! I would cut off the right angles and solder the legs together to form a solid unit, making sure that it fits tightly around the shaft tube!! THEN; when the shaft tube is correctly fitted in the hull and everything is cured cut a slot to fit the bracket into the hull and epoxy it in. Fill and smooth on the outside as needed. Looks better and lasts longer 😉 Again, see the Belfast pic. Cheers Doug 😎 So ends the 17th epistle from admiral Doug😉 Hope it helps!

Crash Tender Shaft Tube Poistion by neilmc Commander   Posted: 2 months ago
I think you're starting to understand how much of a novice I am to this game as simple advice is good for me, as a few thousand pounds worth of pennies has just dropped for me 😂😂😂 I thought it was all done together shaft motor mount etc 😂😂😂😂😂😂 Cheers Doug I may even be able to sleep tonight now knowing the task has just become so much simpler 😉

Crash Tender Shaft Tube Poistion by RNinMunich Fleet Admiral!   Posted: 2 months ago
Good👍😉 The shift it forward of the intake pipe fix and fill it and leave it to cure! THEN fix the motor mount! The motor mount can always be adjusted without having to rip the hull open like for changing / moving the prop shaft. 😊 A problem I currently have with my Graf Spee😭 Doug 😎

Crash Tender Shaft Tube Poistion by neilmc Commander   Posted: 2 months ago
No luckily I was using the pick up tube as a reference point to show in the photo what had been achieved from yours and Dave's advice 😁 I haven't even contemplated making it permanent yet as the motor now needs support alignment etc. To be honest it's all a little much. The replacement shaft I purchaed was a direct replacement for original shaft so no reference was made to the plans. I was content to struggle aligning the motor and shaft with the original IC mount and then just gave up till now lol.

Crash Tender Shaft Tube Poistion by RNinMunich Fleet Admiral!   Posted: 2 months ago
Oh no! I hope you haven't glued and filled it yet😡 If so you're gonna have to cut/break it out again move it forward and adjust the motor mount accordingly. Frankly the length of Dave-M's shaft (😲) is irrelevant. That depends on where he wanted to mount the motor and the length of the coupling he used. What you should have done is- 1 Check the length on the plan before you ordered, 2 Check alignment and position of the prop end relative to rudder etc BEFORE fixing it permanently. Back to the drawing / hacking board 🤔 Cheers Doug 😎
