3D printing by RNinMunich Fleet Admiral!   Posted: 6 hours ago
The Chinese too, check this out! 😲 https://www.huffingtonpost.com/2014/09/08/3d-printed-houses_... 😎

Of course not! It's recycled. They send it round a Black Hole to 'spaghettify' it, then wind it back on the printer spool 😉

Hi Baggie, just Google 'Wherry' and you'll find hundreds! https://www.google.de/search?q=Wherry&dcr=0&tbm=isch&tbo=u&s... Cheers Doug 😎

Billings Sea King refit by RNinMunich Fleet Admiral!   Posted: 2 days ago
Nicely done Allen, All Ship Shape and Bristol Fashion again. 👍

Twin Esc/Mixer by RNinMunich Fleet Admiral!   Posted: 2 days ago
Hi Neil, yes get a couple of singles or one dual board as you wish, same price, fiver a chunk. They make wiring up the motors a doddle. Also think about a few of the switch boards. See link above. Single switches you can use on the 3 on/off toggle switch channels on the Tx; A, B and D. A dual switch version you can use on the two way switch C on the Tx. Make sure they can switch enough current for the load you want to use; esp. the smoker! Don't know what current yours takes, you may have to suck it and see with a multi-meter. Cheers Doug 😎 PS don't forget to tell 'em to send my commission! 😉😉

Hobby Engine 'Richardson' Tug Upgrade by RNinMunich Fleet Admiral!   Posted: 2 days ago
Good news 👍 Well played Sir 😉 BTW: you can't upload video directly to the site. You have to go via You-tube, which means creating an account if you don't already have one. Have a good break, cheers Doug 😎

Hobby Engine 'Richardson' Tug Upgrade by RNinMunich Fleet Admiral!   Posted: 2 days ago
Hi Neil, you can't 'take up' anything from the original board as the receiving and decoding is all done in that large IC, which you are going to replace with the new RX. So you will need switch boards plugged into the new receiver. Doug

Hobby Engine 'Richardson' Tug Upgrade by RNinMunich Fleet Admiral!   Posted: 2 days ago
Yep, a Large scale IC doing most of the work, RX/Decoder, and some power transistors for the outputs. Not easily mod-able 😡 Suggest you have a look at the little switch boards from Action (Component Shop) Neil. http://www.componentshop.co.uk/action-electronics/switches.h... I made my own several years ago using CMOS chips and little 5V relays, but then I'm just like that😉 The Motor Sound Unit I understand looks after itself as it's coupled into the ESC control. So you just need switch boards for lights (nav and deck/cabin lights), smoke, other sound boards, e.g foghorn and/or ship's bell from Action? Have fun, Doug

And......! by RNinMunich Fleet Admiral!   Posted: 2 days ago
Me too!🤔 After two piles of matchwood and one fly-away I started building my destroyer - and learned to swim properly 😉 Still toying with the idea of electrifying my old Simprop Zaunkönig though. Doug 😎

Twin Esc/Mixer by RNinMunich Fleet Admiral!   Posted: 2 days ago
Spot on Jarvo👍 Shame about the fry-up though! Neil, the ESC you have is for 20A (which is overkill!) so the wires are dimensioned for 20A plus a good margin for safety. The tiddly motors in Richardson and Southampton probably only draw about a tenth of that ca 2A or so. Therefore 'tiddly' wires as well😉 BTW: don't forget the fuses! The P95 Fuse/Indicator Boards from Action are quite useful for electronic novices, use standard car type blade fuses, and are dead easy to duplicate on a chunk of matrix (Vero) board😊 Happy modding, cheers Doug 😎

Twin Esc/Mixer by RNinMunich Fleet Admiral!   Posted: 2 days ago
Exactly Dave 👍 Several of us have extolled the virtues of separate Rx batteries. I feel I have more control over what happens when on start-up and testing. For testing I usually use a variable PSU anyway. I also prefer to use drive batteries for just that and not waste endurance supplying servos etc. Finally, for multi-channel setups and/or large servos, winches etc the BEC may simply not have sufficient current capacity. Cheers Doug (aka 'The red-lead snipper'😉)

Welcome aboard Brightwork, very nice collection of boats 👍 Doug 😎

Twin motor control problem by RNinMunich Fleet Admiral!   Posted: 3 days ago
Good luck John 👍 The 'hurricane' brought us a superb Indian Summer here in south Germany, blue skies and 25°C in Munich. 😊 Should last until Saturday, then the rain is back 🤔 It really is an ill wind that blows nobody any good! To avoid the binding timing problem Dave describes above use a separate RX batt and disconnect BOTH BECs!! Then only switch on the ESCs after the TX is bound with the RX. Several RC module manufacturers warn against BECs, e.g. Action Electronics! Happy sailing, Cheers Doug 😎

Twin Esc/Mixer by RNinMunich Fleet Admiral!   Posted: 3 days ago
"slow down and read the manual" That was from me! 😉 Sometimes we have to brake Neil's enthusiasm a little! Cheers Doug 😎

Twin motor control problem by RNinMunich Fleet Admiral!   Posted: 3 days ago
Good, get rid of the mixer until the basics work! 👍 I'm pretty sure the snag is more in the antenna position and/or motor suppression - duff capacitor? - causing a Failsfe condition. Good luck, Doug 😎

LESRO Sportsman mk1 restoration by RNinMunich Fleet Admiral!   Posted: 3 days ago
Wow! We have a celebrity member😉 Welcome aboard. Lucky find in the junk shop, hull looks pretty much like the Sea Scout! Happy renovating, cheers Doug 😎

Twin Esc/Mixer by RNinMunich Fleet Admiral!   Posted: 3 days ago
Hi Neil, sorry but they do tell you that. See pic! Extract from the pdf file data on the site, which one can read before ordering! Check this out- http://www.componentshop.co.uk/pdf/P94.pdf You need the slots for the heat sinks cos you seem to have the 20A version. Which is more than you need for the Richardson I think. I don't need the slots cos I bought the 10A P94 Lite version. What do we learn? Slow down and read the manual and small print 😉 Cheers Doug 😎 Have a good break. Kit-Kat? 😉

Hola Alan, it's made in Holland, maybe you can find a Spanish dealer here http://www.tonkinois.com/gb_algemeen.htm Asta luego, Doug 😎

Layout and Limitations (con) by RNinMunich Fleet Admiral!   Posted: 3 days ago
I agree Neil😉 The Turnigy is a good set and the RX nice and compact and light. Cheers Doug 😎

Twin motor control problem by RNinMunich Fleet Admiral!   Posted: 3 days ago
Hi reilly, Possible, but I would only expect the motor load current to decrease the RX sensitivity if the battery is almost flat and the extra load pushes it below the failsafe voltage limit. John has already confirmed that the battery is/was fully charged. Cheers Doug 😎 PS testing without BEC is a good idea as it would confirm or eliminate the possibility that the RX supply voltage is collapsing and causing a Failsafe condition. I prefer separate RX batteries anyway, fewer surprises😲! Except in the smallest Plastic magic projects where weight is critical.

Twin motor control problem by RNinMunich Fleet Admiral!   Posted: 3 days ago
Hi John, maybe some clues here! "Hints & Tips - FAQs" You may need to make some adjustments on your TX; Failsafe, EPA ... I use Viper Marine 10s without any bother at all😉 Still don't quite understand why it works dry but not wet🤔 UNLESS, poor antenna installation or motor suppression (interference?) is activating the Failsafe. If still set as 'standard' (i.e. for aircraft) on the TX this will most probably be 'Full Back' and needs resetting to the mid point. Most (only?) logical explanation I can see, and changing the ESC won't cure it - but al least you'll have some spares 😉 Good luck, Doug 😎

MFA TORPEDO 500 / BATTERY INFO by RNinMunich Fleet Admiral!   Posted: 4 days ago
Same as mine from HobbyKing, this type comes in various colours under various names but they are all made by Husang in China😉 You can also connect it between charger and battery to measure the charge (capacity in mAh) you've poked into the battery. This you can then compare with what is taken out again when running or testing motors. 👍

MFA TORPEDO 500 / BATTERY INFO by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi al, jarvo's answer is more or less correct but not the whole story! Here is a reprint from my attempt to clarify various misunderstandings and misuse of terms related to batteries - usage and maintenance - posted to a thread "battery charging" you can find under 'General Sailing'. "Hi Both (and all other non-technical guys here!) (Dave_M please jump to the next post or topic!😉) To avoid further confusion amongst the non-technical members can we perhaps straighten out the technical terms involved in battery charging and use (strictly speaking the dimensions or quantities involved). mAh (milli-amphour) is a measure of the capacity of a battery: how many 1/1000 of an ampere (A) it can theoretically deliver in one hour, if in perfect fully charged condition and under perfect environmental conditions. (What you ain't never gonna get!) When the outside temperature drops so does the usable capacity 🤔 Charge and discharge rates are measured in ampere (A). under 1A the milliamp (1A/1000, unit mA) is usually used for convenience. Quality battery packs are marked on the case with maximum charge and discharge rates in A. Sometimes marked as xC/yC. xC is the MAX charge rate and means x times the nominal capacity/1000. yC is the MAX discharge rate (i.e. what your motors take) and often means y times the nominal capacity/1000. Sometimes the max discharge rate is given as a multiple of the max charge rate. See example in my photo. These are MAXIMUM warnings and NOT to be taken as the norm! See example in pic. Capacity 4000mAh = 4Ah, MAX charging current is 8A =2C, (4000/1000)x2. Half an hour charging gives then 8/2=4Ah. I would never ever charge at anywhere near this rate! Charging at 500mA (0.5A) for 8 hours (0.5Ax8h=4Ah) is perfectly adequate and much more gentle on the cells i.e. longer life 😉 MAX discharge current is given as 240A = 30 times max charge current or 60 times capacity in Ah.(4). If I used it at this rate it would probably be irreparably damaged (toasted) in just under a minute (0.9999r) 😡 If any Lixx pack gets HOT while charging or in use take it to recycling pronto, before it sets fire to your boat or workshop/house😡 ALWAYS MAKE CERTAIN THAT YOUR CHARGER IS SET FOR THE TYPE OF PACK YOU ARE USING, NicAD, NiMh, LiPo OR LiION etc (don't forget the balancer connection!). Sorry for teaching some 'grandmas' to suck eggs but having seen so many questions about battery charging and much misuse of the parameter units for batteries in the responses (as above) I felt it was time to clarify things for the non-technical among us, for their own safety and the health of their wallets!" Cheers Doug 😎

Denatured Alcohol by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi Mark, I've taken to wearing a black suit and dark glasses all the time just to confuse 'em 😉

Denatured Alcohol by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi Haverlock, I already got some👍😉 From a German Magic Shop. I have it in the 'Flash Paper' form so I can wad it for gun barrels. And I still have the glow plugs from my heli and Zaunkönig days. 😉 Cheers Doug 😎

MFA TORPEDO 500 / BATTERY INFO by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi al, this is the sort of thing we mean - https://hobbyking.com/en_us/turnigy-180a-watt-meter-and-powe... Not too expensive but can save a lot of expensive mistakes and misery! Used for checking before you get on the water as well as for testing batteries on charge and discharge. Cheers Doug 😎

Denatured Alcohol by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi Mark, Thanks for your concern 👍 but don't worry, as I said that was only tongue in cheek musing / fantasising, although ..... 😉 Black powder for depth charge throwers is my limit at the moment RE PS: that was also my concern 🤔 considering all the monitoring for 'keywords' that goes on these days. Cheers (still on the loose) Doug 😎
