Crash Tender davit info... by robbob Fleet Admiral!   Posted: 2 days ago
Martin. The 'Deck Anti-Slip Finish' bit is on page 4 near the top. Re: Colours. As there seem to be no colour photographs or film of the boats the question of colours for the decks, cabins and roofs is open to speculation but you are quite correct to point out that the plans do not specify white for anything other than the hull markings. The cabin roofs I believe would indeed have a textured coating as the crew were required to stand on them to operate the monitors etc. but I decided not to replicate the texture as is would just look like a bad paint job! I did carefully consider the colour options when painting my boat and decided to texture the deck and paint it in the colour specified ‘BS631 RAF Light Grey’ but to leave the cabin roofs untextured and painted white as that seems to be the consensus, and to my eye it does look 'right'. It is also a great shame, as you say, that one of the most popular RAF boats were so few in numbers and not well documented or photographed during their service life. I have a suspicion that a book of drawings and specifications does exist somewhere as I have seen a few pages that appear to have 'Ministry of Supply' indexes and page references. The 'Plans & Docs' section of this site has some useful information and some 'photos and drawings but they are of very poor quality and resolution. Wouldn't it be nice if whoever has that resource were to make it generally available, I believe it's out there somewhere. We can only hope. Robbob.

LiPo batteries by ronrees Sub-Lieutenant   Posted: 2 months ago
Hi all, Lithium-Ion and Li-Po batteries do not take kindly to being stored long term fully charged. When they are new they will do it but after 2 to 3 years of intermittant use, can start to swell a bit and that is where the dangers start. When you give these cells the final run of the season and they show a charge in the the 3.3 to 3.5 (or so) volts per cell then they can be stored relatively safely. (This is called a holding or factory charge) Re start them with a balanced charge before you next use them. Do not constantly fast charge them as thi could induce swelling of the pack earlier. The old Ammo box is a good idea, any strong metal box will do but store them where it does not get very hot or very cold and ideally not in the house. Lipo cells are accepted as hand luggage by most airlines and a holding charge is recommended when flying, so remember to take a small 12v DC balance charger or 'Intelligent' charger with you to other countries, you will always be sure of a power supply, like a car battery even where the mains voltage is different. Small black plug-in cell monitors are readily available from places like Component shop and are a good guide to cell condition. One is these is quite essential as we use these cells more and more. Cheers, hope this helps. Ron.

Aerokits Patrol Torpedo Boat by MouldBuilder Commander   Posted: 3 months ago
Thanks Doug. Finally found the Robbe on Amazon for £42 plus delivery. I took your advice and ordered it as it appears to be the only one left anywhere. I will leave the battery until I get nearer to the re-launch. I also purchased the monitors and balance unit. There is no point in starting from total scratch. Thought it safer to follow your lead. Thanks. 😊Peter.

Aerokits Patrol Torpedo Boat by RNinMunich Fleet Admiral!   Posted: 3 months ago
PS re Monitor! There are separate 'Alarm' devices (i.e. Monitor) on the market for warning you if the Lipo is approaching the critical low voltage; 3.0 - 3.2V. Look on the sites selling batteries, they usually have the Monitors as well. Some can allegedly be coupled to the feedback telemetry to warn you on the TX display, but i ain't tried that yet 😉 LiPo Safe ESCs can also be programmed to slow down or Stop when the voltage is low. This is (to me) about the only reason to buy a programming card for the ESC. Everything else; stick positions for Full Ahead, Full Astern and All Stop you can do with the TX! 😎 PPS: Before Canabus jumps on me about programming cards! 😲 There is one other reason they can be useful: If you have a Car Escape as Canabus recommends! I discovered that they are usually delivered set up to 'Brake on reverse', which means that you have to shove the gas stick backwards twice to engage reverse. Otherwise it just STOPS!! The programming card enables resetting this to 'Boat Mode' so that the motors reverse immediately you pull the stick back. If you use Marine ESCs this isn't a problem as there ain't no Brake!

LiPo Battery Monitor by Dave M Fleet Admiral!   Posted: 5 months ago
Hi Andy There are many variations on the market but they all work basically the same way. Most modern Lipo ( and all Lithium based batteries) come with a small white plug with multiple contacts as well as the main power plug, usually connected to some heavy duty wires. The plug is connected to the battery negative at one end and then each pin is connected to the negative on the next battery etc. This allows the individual cell voltages to be measured. The monitors do this automatically when connected to the plug the correct way, if it doesn't light up it's probably the wrong way round. In my experience the monitor connector is not marked so you may need to try different combinations to find the correct way. You will not damage anything if you get it wrong. When correctly connected the monitor will display each cell voltage then the total voltage. This usually repeats after a few secs until you disconnect If you have a charger they have a selection of different size sockets for the number of pins and can only be inserted the correct way. You will need the manual that came with the charger to select the correct screen to display the values, but most can be found if you Google. Glad to hear you have a monitor, LiPos can be damaged if not kept balanced, or discharged below 3v ( some are higher, usually the high power versions) Hope his helps

LiPo Battery Monitor by AndyG009 Lieutenant   Posted: 5 months ago
Has anyone had experience with the Lipo Battery Monitors which can monitor 1 to 8 cells, and have a LED (7 segment) read out. If you have do you have any instructions on how to set them up ?

Trojan by solmike Petty Officer   Posted: 9 months ago
[Score: 10/10] 38" Trojan Powered by Lead Acid (12v) 7Amp/h Batteries Controlled Through Mtronic ESC - Comments: Trojan is a graupner Tito Nero kit. Working fire monitors and now thuster. Twin shirtless drives give excellent manoeuvrability.

Sprinkles by Commodore-H Sub-Lieutenant   Posted: 9 months ago
[Score: 10/10] 32"/4500g Sprinkles Capable of 3mph Twin Propellors (3 Blade 45mm) Geared to a Electrofly (3 Blade) Powered by NiMH (9.6v) 5Amp/h Batteries Controlled Through Viper ESC - Comments: Sprinkles is a scratch built U.S. Coast Guard PWB, patrol waterways boat. Operating features include; searchlight and running lights, revolving blue emergency light, rotating radar, and a water monitor that fires 10-15 feet and can I studied various styles of water monitors and finally decided on one that is a composite of several types. Bending the tubing was difficult, nozzle was made on Unimat. Power is from Sig "gas passer" pump. I purchased the rotating beacon on ebay and power is from 5V voltage regulator.

Crash Tender Shaft Tube Poistion by neilmc Commander   Posted: 10 months ago
Hi To you all thank you for the continued advice it is making life so much easier and I do like it when the thinking is done by experts. Paul The disc idea is an absolute bonus and will be using it for sure as it takes away the need for continued measurements. Dave The water scoop is going as like you and Doug say I don't need it no working monitors for me, just a working boat would be good. I'll be using measurements given to achieve shaft positioning as at the moment I have a 2 blade prop which I think is 30mm diameter so disc to suit will be used. Doug I like KISS it's worked for me loads of times in the past but I can't help buying shining things 😁😁😁 The shim idea on the prop tube is a good one but may still go for a support even though not needed it shines 🤣🤣🤣🤣. But it may still go back to the filler piece as all depends on how difficult it is to fit the A frame support. I purchased one at 8mm for the tube and not 4mm for the shaft. I'm looking forward to the weekend to get started and even set an alarm for an early start which is unusual for me. Im off to HMS Alliance as I do volunteer guiding there otherwise Id be starting now. Will keep you all posted hopefully with good news and no more questions - well on this bit anyway 🤣🤣

what motor by RNinMunich Fleet Admiral!   Posted: 10 months ago
OK. So it's 4" smaller than the Sea Scout I am currently renovating and upgrading from a 50ies Taycol motor to brushless! So keep the 'stuf' lightweight. When I asked the same question for the Sea Scout a few months ago I got the following advice from Canabus, who seems to have considerable experience in this field 👍 "All from Hobbyking. Motor propdrive V2 2830- 1000kv 370watts 3.175mm shaft(9190000328-0)3S or 4S lipo battery. ESC 30A car(HK-30A)( XT60 connectors required), program card (HKPROG-CARD)can be used on the larger ones in the series. Lipo battery Turnigy 1000mah 3S 30C (T1000.3s.20) 89grams 75 x 33 x 19mm or a Turnigy 1500mah 3S 25C (T1500.3S.25) 113 grams 80 x 34 x 25 mm both have XT60 connectors. Prop about a 2 blade 30mm 1.4 pitch" I actually opted for a 3 blade prop and a 3S 3000mAh I already had, but bought the ESC and motor recommended and am now fitting them cos it made sense, was not expensive and came pretty quick - make sure it comes from the UK or EU warehouse to avoid possible import tax from Hong Kong or USA !!! This would be more than adequate to give your boat some Oomph! It needs more than my cabin Cruiser! For the RC buy a complete set already matched and 'bound' so you have the minimum of fiddling about as a rookie😉 I can thoroughly recommend the Turnigy HT6, AKA TGY-I6 , ~US$45 also from Hobby King. In a couple of hours one evening I could programme two models into it and get it to do what I wanted instead of what the factory thought we would want for plane or chopper! Instructions are quite clear, logical and lead you through step by step. It comes with a 68 page manual! But much you can skip if you don't intend to go flying with your boat! Attached is a pic from my manual with German branding (REELY)! But it's the same beast as the TGY-I6, second pic!! The whole package should cost around a 100quid and you're RTR! The RC set has 6 channels so you have lots of scope later for special functions; fire monitors, lights, horn, motor noise etc etc 👍 By the way; the motor comes with 3.5mm bullet connectors, and of course I only had 4mm 'other halves' but you can also get connectors, loose or fitted to cables and adapters at Hobby King. (You can solder them on with your 4lb hatchet!!!) Hope this helps, Cheers Doug 😎 PS don't forget a suitable coupling to match the 3.17mm motor shaft to your prop shaft (whatever that is, 4mm?)

Conrad REELY, Flysky iA6, FS iS6, Turnigy HT6 !! by rolfman2000 Fleet Admiral!   Posted: 10 months ago
Most of the companies you have mentioned tend to rebadge third party suppliers hardware, and put their own firmware on it. Flysky and Turnigy normally won't work together, but, if you install Turnigy with Turnigy, or Flysky with Flysky, it will work. I have successfully "updated" Turnigy receivers with Flysky firmware updates to enable me to use them with my Flysky Transmitter. My next job is to hack my Flysky GT3-B to increase to 8 channels and ppm transmission, so I can install an 8 channel receiver on my 46" fire tender (sound, directional working fire monitors, etc). Hopefully doing it sometime next week. Progress reports as(or if) I make any 😨 Best wishes, Dave W 😊

Tank Steering by RNinMunich Fleet Admiral!   Posted: 11 months ago
Hi Dave, you won't find a Conrad anything anywhere else but on the Conrad (or Amazon/Ebay) sites! But if you look for the Turnigy HT-6 you will find it on HobbyKing, it's the same damn thing for nearly half the Conrad price. See pics. Pure badge 'engineering'! Also just bought some Absima LiPos 2s 4000mAh from Conrad, €40 each. Today I found out that Absima is in Nürnberg (Nuremberg) just up the road from here, same batt €25 😡😭 Conrad will shortly be getting an appropriate mail from me! NO more Reely stuff for me!! I found the HT-6 very easy to set up, amazing what they pack into a $45 set these days. My Spektrum cost 12 times that a few years ago and doesn't do an awful lot more and is more complex to set up 🤔 Won't mess with mixer boards or two stick motor control just yet. Can use the mixer functions in the TX 😊 Have tested the HT-6 with various ESCs; e.g. Graupner Navy VR30 and Mtroniks Viper Micro10, no problems. When the new 2s LiPos are charged the next test will be with a Turnigy brushless ESCs and the BL I want to put in the Sea Scout. Progress is slow but sure. Why do I get on faster with electronics than with shipbuilding!!?? 😉 You're right; Mode 1 or 2 (3 and 4 are also available!) don't matter much. With this set you can assign any control element stick, switch, or pot to any channel (i.e. RX output) you want, and very simply - not like the Spektrum🤔. Like it.👍 I also like having the two pots available for proportional control; gun turrets, cranes, monitors .... 👍 And still switches left over for lights, sound .... Very versatile 👍👍 Only irritation is it won't go into operational mode until all switches are forward and the throttle (left stick) is pulled right back - motor off for an aircraft - safety feature. Minor irritation for a boater but pull the stick back and all is OK and you can then operate normally. Used the spring removal method on my old Graupner 40Meg MC-10. That box was a pain to set up as well🤔 I could programme the radio ATE for the old Home Office Type Approval lab faster, but then - I wrote the software 😉 Cheers Doug 😎

DJI Phantom 2 v2.2 drone by none Fleet Admiral!   Posted: 1 year ago
DJI Phantom 2 v2.2. Anyone fly one of these. Here are the specs of the one I am looking at. But seems due to all the bits it has to carry the total flying time is 16 mins .. Is this long enough for a general flight ? Any here are the specs DJI Phantom 2 v2.0 Fully kitted out with Live video feed to the controller, has the excellent Zenmuse H3-3D stabilised gimbal fitted and has the brilliant Gopro hero 3+ black edition included for excellent results. It has an immersion RC 600mw video transmitter fitted for long range transmission and this is fitted with a Fat shark omni directional higher gain antenna. The controller has a Flysight black pearl monitor fitted with the latest folding sunshade. As it has dual 5.8ghz recievers and 32 channels it has twin antenna mounts on top of monitor and there is a fat shark omni directional antenna to match the one on the video transmitter on the drone and also a 5 turn helical directional antenna for solid video at extended distances. The monitors inbuilt diversity reciever will auto switch between antennas to get the best signal. This comes with all original boxes and 2 sets of propellers one of which have never been out of the box. This drone has the heads up display module already fitted to give you live flight data and heading to find back to home if orientation is lost. As with all Phantoms this drone has auto return to home and land so if connection is lost it will fly back to land at its take off point. This drone includes all chargers etc so is all you need to get flying and capturing great aerial footage in a single kit. I have flown this out to 997m during testing and it is faultless in its reliability. Three flight batteries are included to keep you flying longer. This is a very capable machine that has done some epic flights. I am happy to demonstrate it flying etc as it has never been crashed or abused. So what would you think was a fair price to pay for this drone ????

searchlights by peterfoster Seaman   Posted: 1 year ago
has anyone got any suggestions for making your own searchlights, fire water/foam monitors. scale approx. 1/43 1/50 I am struggling to build at that scale with much detail?

The fire monitors by robbob Fleet Admiral!   Posted: 1 year ago
Hi Allenrod. Perhaps if I ever do a refit on this model I might consider working fire monitors but as it was never part of my original plan it would be very difficult to incorporate now. Besides, I have had my brother doing a little bit more brass turning for me as you will soon see in some forthcoming posts.😉 Rob.
