M. V. TEAKWOOD by RHBaker Fleet Admiral!   Posted: 12 days ago
Finished the major parts of the hull and am satisfied with the results. Now turned to the superstructure, which has turned into a challenge in its own right. Decided to break the structure down into decks and concentrate on each deck individually; before “rolling them up” into the complete structure. Also decided to make the central “core” first and complete, before adding the curved frontispiece containing the forward bulwarks. This would allow all the detail between the two such as windows, doors and portholes to be accurately made and positioned. The structure from the first deck upwards was made removable to gain access to the internal systems of this working model. The lovely flowing curves, which attracted me to the vessel initially, proved a pain to reproduce. The bends around the front corners required making each deck front separately and then gently bending heated styrene around a former to reproduce. There is much opportunity for hurling! Added a L shaped strip around the front of each deck, so there is something firm to glue the front bulwarks to. Was concerned that without something like that the individual deck shields would never line up properly. Similarly added styrene U channel along the deck edges to give a surface to which the shield side rails could be fitted. This also replicates the vertical deck edge panels that are evident in pictures. Felt this would also make the structure more robust, enabling it to be removed and refitted without damage.

Safely Packed ??? by Dave M Fleet Admiral!   Posted: 14 days ago
All down to standardisation of size. Did you see the News program the other day visiting their new distribution centre. All automated with the system deciding what goes where and when. The box size is chosen. My local courier told me that they do not use small boxes as they get lost and economies of scale dictate the sizes used. I also buy from RS Components and they deliver each item in a white bag packaged in a bubble bag and then all enclosed in a larger bubble bag. You can order up to 10pm and it arrives first thing next morning ( might be because I am adjacent to an M6 junction). If you have friends who are moving the Amazon boxes and paper are ideal for packaging small items.

Sound System Try Out by NPJ Captain   Posted: 1 month ago
Fortunately too late for the little beasties, but the Astronomy stuff I took with me stayed in the car! The Galloway Forest was very clouded and misty. I failed to put the sources in for the bits I am using. Will do that on next post. All the best NPJ

Rain in Scotland , now that's a rarity hope you enjoyed our national drink or even our other national drink and the midges didn't bite too much .👍 Cheers Marky

Sound System Try Out by NPJ Captain   Posted: 1 month ago
Well, back now from a wet Scottish break and with lots of little parcels to open..... Just before I left I tried to load a video and failed. My 'tutors' are going to help me with that but for now, the photos will do the job. The first image shows my temporary power setup and the layout of the components (1). Exciters sourced from ............. and the sound unit is a ............. Note the way they are wired up. I hope, when fitted properly, the cabling will run across the bottom of the Hull. The positioning was very much dictated by the space available between one set of 'ribs' (2). This seems to be just perfect. Note the position of the solder tags(3). There is little space left at the top when fitting the Deck, so keep as high as possible bearing that in mind. So I put the exciters in place, and attached my power supply (4). I could not wait to put the Deck back on before I tried, but at least I had sound of Motors and Horn and adjusted the volume control to 75% (5) Volume control being the white block with the cross head. So after I had my fun, I tidied it all up and put the deck on. Not screwed down but just to check sound levels. Did not work first time because of the lose wires, but second time was good and a great depth of sound. So that has confirmed the sound system fits and can work in that position. However, that is without motors running and that may make a difference. Next time I hope to be doing the trials of the mixer/escapes and motors, then I will see how the sound presents with motors running. All the best. NPJ

ONLY REMOVE THE FERRITE COILS IF YOUR GOING TO USE 2.4GHZ. I found that the Ferrite Coils Interfered with the RC System!

Huntress - Rudder by AndyG009 Sub-Lieutenant   Posted: 1 month ago
A Fairey Huntress has a Rudder system where the Rudder, and the Rudder 'post' are outside the Hull, located on the transom. With the operating arm going into the hull. Has anyone had experience of this sort of set up on a model ? I know that the normal way round it is to fit a Rudder in the usually way, i.e. through a tube located through the keel.

Motor problem by Haverlock Fleet Admiral!   Posted: 1 month ago
before you fit a water cooling system try a smaller prop. You need to think of the gearbox in a car. Too big a prop can be looked at as being like trying to drive off in top gear! A smaller prop will allow any given motor to spin faster and strange as it may seem use LESS not more current. If you keep the drawn current down to the limits set by the motor constructor then its probable you will need no extra cooling. If the boat moves faster than you want use the throttle its what its for. Throttling down also extends battery life. The air intakes on boats like this were intended for IC engines and they NEED air to work.

new brighton model boat lake by boaty Commander   Posted: 1 month ago
Hi Steve Its fresh water but the much larger Marine Lake a quarter of a mile up the road is salt water. I don't know if you are allowed to sail models there. I used it once in the 1990s with a fast electric but had to flush out the cooling system after. Went in the early morning when it was quiet so I didn't get spotted. Boaty😊

Motor problem by scout13 Chief Petty Officer   Posted: 1 month ago
how have you got the batteries connected each pack is 7*2v have you wired them so it is putting to much power to the motor also looks as though you have covered up all the air vents to the motor also try a fuse in the system it saves blowing up speed controllers hope this helps

RSS P71 Sovereignty by cormorant Fleet Admiral!   Posted: 1 month ago
Almost complete Veron kit based on the Vosper 110' fast attack craft built for the Republic of Singapore Navy in the early '70s. Fitted with a Shockwave 2 sound system I propose to fit ultra bright LED to the main armament to represent muzzle flash to sync with the sound system.

M.V. TEAKWOOD by RHBaker Fleet Admiral!   Posted: 1 month ago
The only remaining area requiring significant rework was the bow. Decided now to concentrate on getting the shape and dimensions correct. Made a template from a steel wire coat hangar, shaped to follow the Teakwood bow profile. Cut a mating recess in the upper bow and bulwark, fitted the template into it using CA glue. Once fitted and relatively rigid, cut a piece of styrene to fit into the space between the hull and the template. Epoxied the styrene into place at both the template and to original Velarde hull bow profile. This gave a nice looking bow from the side elevation, one that is also strong. Unfortunately, when viewed from the underside, the usual nice smooth water entry is not apparent. Had two ideas to attempt to blend the bow into the hull sides properly. The first was to cover this transition area with thin styrene and then feather it into the bow and the hull. The second was to use the modelers secret weapon, wood filler and do the same. After either approach planned to cover the whole area in thin glass-fibre cloth and sand down until smooth. Mocked up the styrene installation and decided to abandon the idea. The styrene makes the bow transition bulky, it also became quite clumsy around the upper area. Thought would try the wood filler approach instead. Shaped the rough filler with sand paper, it worked out relatively easily as it required little rubbing down. The modification worked out well and the bow looks satisfactory from both the side and underside. Decided also to replace the pulley drive arrangement with a toothed belt system. Have never tried this before and, as a friend of mine had a selection of belts and pulleys, thought would be useful experience to try it. One question perhaps somebody can help me with – what colour was the deck on this vessel? All my pictures showing the deck are in black and white!

Aerials etc. by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Norm, have seen nothing like that in any photo I have? Don't believe it was like that anyway, very impractical 🤔 Maybe it's just a fuzzy pic of the DF aerial. I also note that the DF aerial is not there on some photos. So; another case of 'you pays yer money and yer tales yer choice'! Yes, wire antenna only on the last three masts. There was nothing strung between the forward masts and the aft masts for four reasons: 1) the span is too long, 2) they would not want to roast the Island crew when transmitting Hi power HF from the starboard antenna in particular, 3) neither would they want to irradiate the ammo for the flak guns! 4) the forward masts were reserved for the vertical antennas. This gave the system the so called polarisation diversity; vertical is better for short range ground wave and the horizontal for filling in the 'skip zone' of vertical antennas. That is the gap of a few hundred miles between the short range ground wave and the long range sky waves. Bet you really wanted to know that didn't you?😉 Naval ship antenna layout design was part of my job for 30 years. Cheers Doug 😎 PS there would have been no halyards on the tilt-able masts. These are on the two fixed island masts, on the Signal Deck.
