run time
VolantexRC ATOMIC RTR racing boat by Dom of Essential RC Lieutenant   Posted: 4 hours ago
Having reviewed many planes, quads and cars over the last 3 years so it was refreshing to get a boat in the water. Why didn't I do this a long time ago? Bit addictive to say the least. Was surprised how quick this thing was on 3 cells. Lots of tight turns and no hint of it tipping. And a good run time not far off the manufacturers stated 8 minutes. Balance seemed to be quite critical though. The stock 3S2500 in the battery holder had it on step from the go. I dropped in a 3S2200 and despite pushing it to the furthest forward point it would bog down when it lost momentum. Easily solved with a little lead on some velcro next time out. Otherwise really impressed. Zero time to set it up. Nice it has rates dial for steering on the transmitter so can go between hooligan style tight turns and smooth high speed turns. Looking forward to taking it out again.

Finally it's completed by Rod Commander   Posted: 10 days ago
Six months ago I drew up the plans for my Jet Sprint boat and at last it is completed and ready for its first test run Very happy with results so far so hope it performs well on the water Have leak and ballast tested it and all good so here's hoping for a successful first run up the river Has been a real challenge at times but well worth it and a lot of satisfaction and fun making it I have named it "Rapid Hoppa " so I hope you all like it Will post a video of its on the water performance as soon as I can

baking soda sub by RNinMunich Fleet Admiral!   Posted: 11 days ago
My latest passion (!) is Lagavulin! I have a 2000er, bottled 2016, just about to run out 😭😭 Must investigate Pulteney! There's great Whisky specialist shop here in Munich 😜 Time to go sampling again 😉

Re Sea Rover by Wingcoax by RNinMunich Fleet Admiral!   Posted: 11 days ago
Wow! You had the 'posh' version of the Bell battery with screw terminals! Mine only had brass strips and I was forever cleaning them with Brasso 🤔 Granny & Grandad used to help keep Hotspur running. She got most use when visiting them in Folkestone anyway. Near where I lived, RAF Cosford, I had nowhere to sail her! By the time I got around to glowplugs, Simprop 'Zaunkönig' and a little heli from Great Planes, the reliable 2V SLAs from Yeasu and similar had appeared. Just found the bits of Zaunkönig in the cellar, looking very sorry for herself! 😲 Time to think about upgrading to a brushless!? Advice from the experienced flyboys welcome! Cheers Doug 😎 PS The 'manky hanky' sounds familiar, I had used mine to clean the terminals of the wet cells Dad had fitted in our Sea Scout 😲 And they were 'WET'!

Decks by RNinMunich Fleet Admiral!   Posted: 12 days ago
Hi Norm, The whole Operation Pedestal story is incredible! What else could they do with Ohio? Broken back and had been sitting on the bottom for a few years! For some time the upper (dry) decks were converted to troop accommodation. Re Carley floats: "The Carley float was formed from a length of copper or steel tubing 12–20 inches (30–50 cm) in diameter bent into an oval ring.[3] The ring was surrounded by a buoyant mass of kapok or cork, and then covered with a layer of canvas rendered waterproof via painting or doping.[4] The metal tube was divided into waterproof compartments with vertical baffles.[4] The raft was thus rigid, and could remain buoyant, floating equally well with either side uppermost, even if the waterproof outer was punctured. The floor of the raft was made from a wood or webbing grating. Boxes containing paddles, water, rations and survival equipment were lashed to the floor grating. Men could either sit around the rim of the raft, or, if in the water, cling to rope loops strung around its edge.[5] The largest model could accommodate up to fifty men, half inside the raft, and the others in the water holding onto the ropes." By the way; the Carley rafts on the stbd side of Lusty seem to be at least double stacked and lashed! Pic 1 shows detail of Carley rafts on HMS Rodney. You can just make out the boxes with paddles an' stuff! Note what looks like an ER Artificer lounging in a doorway while the 'matelots' are swabbing the deck! 😉 Pic must be a fairly early one cos you can see a useless Vickers Quad 0.5" machine gun on the upper sponson. These were rapidly replaced with 20mm Oerlikons after the first experiences in action! Re 'round structure on mainmast': NO! No glazing, it doesn't seem to have been manned and certainly wasn't a 'Fighting Top'. Seems more likely it was a canvas protection ( from weather and curious eyes!) for a radar antenna. Best pic I have of it shows it as not really round but 'panelled'. No openings at all. Access to it is by a short ladder at the rear from the small deck just below it, see pic 2. From the uniforms of the MPs I would guess that this was taken during her repair / refit in the US. Curious is that it is difficult to ascertain when she had this 'thing' and when it was removed. Probably during one of the many radar upgrades. Most early pics seem to show it, by 1945 in Sydney it was gone (pics 4 & 5). Re rebuilding the island; a razor saw would help to remove it, then sand the deck flat. But sometime we have to decide what date and refit / repair status you want to depict!! 🤔 Have fun in UK, say hello to 'Blighty' and sink a pint (or two😉) of 'Spitfire' and/or Breakspear XXX for me. 😉 Cheers Doug 😎

Crash Tender Shaft Tube Poistion by RNinMunich Fleet Admiral!   Posted: 27 days ago
Hi Neil, Freut mich! As they say around here. (Glad about that!) Clever lady! Greetings to the Boss 😊 BTW; I added some extra comments about the battery, possible LiPo, lighter weight would provide even more capacity and longer running times! Whatever you do have fun with it, and enjoy the dinner 👍😉 All the very best, Doug 😎

Crash Tender Shaft Tube Poistion by RNinMunich Fleet Admiral!   Posted: 28 days ago
Agreed. But don't we also want efficiency? Good manoeuvrability, minimum drag and longest running time from the battery! Some basic principles and guidelines are always useful, especially as you say to restorers; as this blog started. Cheers Doug 😎

Dauntless by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Nick, which Dauntless? See pics 😉 Size (LoA & Beam)? Weight? Motor? ESC? Prop? Desired run time? Without this basic info it's like asking 'How long is a piece of string'! BTW: how did your other little problem turn out?? Cheers Doug 😎

Dirty Deeds by Krampus Commander   Posted: 2 months ago
Thank you, AllenA! Well, no science behind the running time. As long as I run at low speeds it just happens everything seems fine. But when I put the throttle down... then all is over within 15 minutes or so. I pretty much stick to the same power layout. 540 motors with 30A controllers, 2000 or higher mAh capacity and 35mm or 40mm props and 4mm shafts. Dirty Deeds is a bit special. I was on my learning curve (I'm still there!) so due to a novice error I used a 2mm shaft so I had to get a special propeller and a big mean battery (kind of a Viagra approach). So, I had a 4-bladed 35mm propeller bored for the 2mm shaft and a 10.8v 4000 mah battery pack. A bit in the heavy side but it gave the boat nice stability. I can achieve better running time with Lipos, but I'm an old-fashioned guy still concerned with the maintenance Lipos involve and do appreciate a bit more of the weight offered by NIHMs, not to mention I'm a cheap guy (LOL). Something that really worked for me is the choice of propellers. I noticed a remarkable run-time difference between plastic and metal (yes, more expensive) propellers, but it is well-spent money. Other boats I have run with 9.8v 2000 mAH batteries achieving almost 50 min at low speeds, which is OK with some of my models for realistic ride purposes. Here I have my two "inspirational" pics.

Dirty Deeds by AllenA Captain   Posted: 2 months ago
Hi Krampus, when I first saw Dirty Deeds I was tempted to call her 'cute' until I looked her up in your harbour. She really is quite a beast. I notice you manage to achieve 50 minutes runtime on many of your boats. How do you balance motor, battery etc to achieve this?

U37 by mactin Sub-Lieutenant   Posted: 2 months ago
Hello MBWs U37 is made from 3 recycled Go system butane gas cans, clockwork as usual and about half way through the build. Im also trying to embrace new technology but its not easy because im a Luddite. The boat will end up 22" long and will dynamic dive or surface run. Total build time so far around 40 hours.

Sea Queen refurbishment by Dave M Fleet Admiral!   Posted: 2 months ago
Hi Doug Resin is heavy and applying by coating the inside of a boat will if the wood is porous absorb lots and greatly increase the weight. The thinner it is the more it will be absorbed. Layup resin is of a similar consistency to liquid brushing paint (not the gel type). It goes more pourable as the temperature increases. It is much thinner than the Isopon resin sold in many car repair packs. Adding styrene will thin the mixture allowing it to penetrate the glass cloth or matting. It is worked well into the mat to keep the weight to a minimum and any excess is mopped up with paper towels. After several coats the fibreglass will be formed and dries rock hard over a couple of days if the correct temperature is maintained. High temps will reduce the time but will be more difficult to work with as the gel stage will happen much quicker. Sorry to rabbit on a bit but I am trying to warn you that you may end up with a very heavy model if you do not use sparingly. If you can get the consistency similar to yacht varnish you can, like me, paint inside the boat including the underside of the deck. Paint out any runs and remove any excess with paper towels. You really only need a very thin coating. If you need to add strength then use some cloth or matting and work the resin well in and mop off any excess with paper towels. If you want to use your brushes and mixing pots again Acetone is the best cleaner but do keep it away from the resin. Both your alternatives would work just as well. It must be Summertime as we keep having rain showers! Cheers Dave
