A SPLASH IN THE WATER by Les-Forbes Sub-Lieutenant   Posted: 6 hours ago
I'm not a member of any model boat club yet, but I am about to join two that I have visited recently, where the member's have been very welcoming. They even said that if was sailing my boat and got into difficulty, they would wade out and rescue if the boat got stuck in any obstruction under the water. That got me thinking. If I was to sail my boat at any pond or small lake etc and I did get into difficulty and did not have a 'Rescue Boat' I would need to have some sort of protective clothes. These waders and wellingtons both come to less than twenty pounds. Is that a good buy.

JOINING BATTERY & RECEIVER CABLE by RNinMunich Fleet Admiral!   Posted: 2 days ago
Hi Les, then I assume that you need something like this harness with JR/Hitec male & female plug/socket. This one also has a third plug for connecting the battery to a charger when the switch is in the off position. DON'T use this feature if you are using a LiPo battery!! There are several other versions without this third plug available here http://www.componentshop.co.uk/futaba-charging-switch-harnes... I guess the RX battery is a fairly small NiMH and also has the JR type plug. BTW: something to check before switching on- Does your speed controller have a BEC circuit? If so it supplies the RX as well so you don't need an RX battery at all. Or doesn't your yacht have any auxiliary motor and ESC? Happy sailing, Cheers Doug 😎 Looking forward to the video of the insulting tape 😁😉 or is that what I keep seeing on the news with Mr T??

Sunk Boat Marker Buoy System by RNinMunich Fleet Admiral!   Posted: 3 days ago
Hi Colin, Ta for the tip. Found this on a German web site Beta Telescopic 1276114 glass EVA AOG TELE 2,10 m 0.59 m Medium 154 g 14.90 € (Approx 13 quid) http://www.shakespeare-angelgeraete.de/catalogue/ruten,20778... style='background-color:yellow;'>escopic,8160.html No sign of a Shakespeare 20 🤔 Still, could be useful! You never know!! Thinks; will someone start asking awkward questions about a fishing license?? 😲 Cheers Doug 😎

Simprop Zaunkönig (Wren) by RNinMunich Fleet Admiral!   Posted: 6 days ago
Spin off from " Re Sea Rover by Wingcoax" ! This ain't a boat, so do I have to convert it to a float-plane to qualify for help here!!?? i know some of you guys are experienced fliers. 👍 After an exchange about batteries and glow plugs etc I dug my old Zaunkönig (Wren in English) out of the cellar and she was in a pretty sorry state Pic 1 🤔 Have now cleaned it up a bit (judicious use of Cillit Bang and a fine mesh scouring pad!) and she looks much more cheerful. Pics 2 and 3. Original Wen Mac/Cox 0.49 long since removed (still kicking around somewhere) and I would like to electrify it. Any advice on motor, prop etc would be extremely welcome. Purists will note that I have extended the top plane, from original 410mm to 615mm! This is an attempt to improve the glide characteristic and above all dampen the incredible roll rate! A gentle bank could suddenly turn into a twinkle roll so fast you couldn't count 🤔 Mod never tested due to move to Germany, new career, new lady, and the demise of many IC flying fields. I have loads of mini and micro servos, pico RXs (yes Dave, some 35MHz!) so they aren't a problem. But what motor, prop, ESC, battery? Have thought of Micron radio for a combi RX/ESC or a mini ESC with one of my pico RXs, but have no idea for motor and prop! Original prop is 15cm diameter. Pitch ?? Total weight of all the bits you can see here is 156gm. Would be nice to get a bit of history into the air. All contributions gratefully received 😉 Cheers Doug 😎 PS: she doesn't need to be a 'rocket' just tootling around would suit my flying skills!😉 PPS: plan in background is HMS ARK ROYAL (WW2) scale ~1:192.

Re Sea Rover by Wingcoax by RNinMunich Fleet Admiral!   Posted: 7 days ago
Hi, Sounds good, but where are the pics?? Oh how I remember the Lantern batteries big square lumps with two conical (or comical?) springs on top. And the flat pack 'Bell' batteries which no one used for bells! These were the staple diet of my 1/72 HMS Hotspur when first built in the mid sixties. No RC, just set the tiller, hidden under a depth-charge rack on the stern, and let her go. Often had to be rescued by Mum and I walking 100yds of fishing line around the lake🤔 Ooops! Sorry madam 😲 Pics show her on sea trials in Radnor Park Folkestone ca August 1966. Captain must have been just 15! Last pic is how she looks now - currently undergoing complete engineering refit. Cheers Doug 😎 PS Portimoa!! Nice place to live. I remember the market hall on the harbour front well, and the great fish restaurants on the other side of the inlet😋 "I'll have that one please - grilled" delicious.

Red Cat hydroplane by SimpleSailor Chief Petty Officer   Posted: 7 days ago
Hi. The HK controller is an Aquastar 120Amp water cooled which has suffered all of the burn outs and never failed. SKU: 9052000008. The failed motors were all 2848SL 3900kv Brushless Inrunner (WaterCooled) SKU:3900-2848SL. I have my doubts about the specifications as their watts and amps do not add up. I have a temperature sensor on the motor sending info back to the TX and usually after a full charge and a fast run it would get to 60°C, then I would cool it to 45°C before the next run it burnt out at 85°C when I wasn't paying attention. The new motor runs at about 45°C how ever hard it is pushed. Still using the 120A ESC. The new motor was in the HK sale and I don't think they do it now SKU:S2858-2630. It just happend that the water jacket for the failed unit fits it.

Crash Tender Shaft Tube Poistion by pmdevlin Fleet Admiral!   Posted: 11 days ago
Hi Doug (time for bed now!) dont know to this day what it was, water was high, it was winter, its a big lake, no sign of something floating, but it was a right loud whack! It was in my home town of Liverpool, so maybe was a stolen car or shopping trolley dropped in the lake!😁 I was convinced it was a right off, luckily it survived! (you had a much better description of the skeg!)

Added extras by Skydive130 Chief Petty Officer   Posted: 11 days ago
Here are some shots of the main plan and the proposed electronics going into my Solent. My only issue is whether my choice of motors is suitable? I've gone with 2 x 600 brushed motors on 15 inch shafts and 45mm brass props which I purchased before reading the article in Septembers model boats mag. The author in that has gone with 2 x 850's? With my aircraft experience, it's strange going "backwards" with brushed motors instead of the aircraft industry standard of using brushless motors, esc's and lipo battery's! And to cap it all, I've not go any aircraft that could possibly drag let alone lift the 12v 7amp lead acid battery that I've bought for this boat! Any thoughts on motor choice would be appreciated, apart from that I'm good with the electrics. The Mtroniks sound board and speaker is a blast using the Napier diesel sound chip. Another shot shows some of the decor going on, i.e. RNLI decals, numbering for "Douglas Currie", portholes, anchor, handrail stanchions. Other decor, doors, bollards etc coming from Macs soon. Last show shows the finished working radar built from scrap and painted in VW brilliant orange which I believe is a recognised match. One last question, can someone please give me an approx size for the 3mm main deck stanchions which I will fashion from brass tube and soldered eyelets, rope thickness would be helpful too, many thanks

Aerokits Solent Class Lifeboat by Skydive130 Chief Petty Officer   Posted: 11 days ago
I am a modeller of 45 years experience, mostly with RC aircraft but have recently got into boats. Have completed the aeronaut Diva and spitfire to a high standard but needed a challenge So, having spent a long time trying to source an un-started Aerokits Solent, I bit the bullet and bought a set of plans and templates from eBay. Overall the plans are good, the templates need some adjusting as we go for acuaracy. Have spent the last couple of weeks perusing the plans and sourcing the materials needed. A visit to the Balsa Cabin in Maldon, Essex provided all the ply and the internet has provided the main components I.e motors, props, shafts, ESC, battery, soundboard/speaker, servo mostly sourced from Cornwall model boats and Howes Models septembers issue of "model boats" had a great article on a refurb which has been very useful for hints n tips on required electrics and the little extras needed to complete. I do have a workshop where the model will spend most of its time, however my wife's conservatory has been invaluable for using my eBay sourced scroll saw to cut out the formers! The sheet of 6mm ply from balsa cabin was long enough to make keel formers 1 & 2 one piece! I shall post a more detailed update when I get my computer back from repair Monday!

Naval History - PQ17 by RNinMunich Fleet Admiral!   Posted: 12 days ago
Sorry couldn't resist this - dry British humour at it's best😉 Extract from the history of PQ17, disastrous arctic convoy to Russia- 'The convoy was now entering the zone of the Barents Sea where enemy surface attack was most likely to happen. Lt. Beckley (P614), the senior Officer of one of the two British Submarines taking passage in the middle of the convoy, flashed to Senior Officer Escorts, "In the event of attack by enemy forces propose to remain on the surface." Commander Jack Broome in the destroyer H.M.S. Keppel (ever the humorist) promptly flashed back, "So do I!" ' A classic! Found while researching Flower Class corvettes - HMS Poppy.😉 Cheers Doug 😎

Tilgear by RNinMunich Fleet Admiral!   Posted: 12 days ago
Hmmm! Are you sure he has more knowledge? Polyanthus has little or nothing to do with 'Pink' but Pinks belong to the Dianthus genus - Dianthus plumarius. Dianthus (K95) survived the war to be eventually scrapped in 1969. She was decommissioned and sold for civilian use after the war, and became the Norwegian buoy tender Thorslep. She was later used for whaling (which this type of hull was actually designed for!) before being scrapped in 1969. Builder: Henry Robb Ltd. Laid down: 31 October 1939 Launched: 9 July 1940 Commissioned: 17 March 1941 Out of service: May 1947 Fate: scrapped 1969 Polyanthus (K47) had less luck 🤔 Sunk while on escort duty with Convoy ON202 by German submarine U-952 on 21 September 1943, while trying to rescue the crew from the destroyer escort HMCS St. Croix, sunk earlier by U-305 . https://en.wikipedia.org/wiki/Henry_Robb Doug 😎 Additional interesting info http://www.cbrnp.com/RNP/Flower/ARTICLES/Dianthus-2.htm

34" Precedent Huntsman by Novagsi0 Sub-Lieutenant   Posted: 12 days ago
Thanks for the detailed reply however I missed your post and had bit the bullet and ordered the 850 motor. I decided to get the lipo safe 50A ESC, and first impression it's a beast of a motor. Maybe phase 2 will be a brushless setup at a later stage. Im hoping a lipo pack will save enough weight to give it some of the offshore PB performance it details in the instructions. :-)

Crash Tender Shaft Tube Poistion by RNinMunich Fleet Admiral!   Posted: 12 days ago
Yep! KISS; Keep It Stupid & Simple!! 😎 Most of my ships have twin or more screws so I need the brackets. But not on my single screw Sea Scout or fish cutter. 😉 Only ever had a water scoop to supply a pump for a fire monitor experiment. Mostly used to keep little boys fingers at a distance 😁 Up to now have never needed water cooling, at most a fan (ex PC processor fan) for the ESC. Cheers Doug 😎
