  1. Thanks John, Not a problem, just interesting to know. It did initially appear under Latest Posts a day or so ago, otherwise I would not have seen it then. Brian.
  2. Yes I can, straight after the Laser Engines thread… What did you do? Brian.
  3. Mine’s the same as yours Martin, it doesn’t show the thread that you refer to either (and I haven’t posted in that thread myself). It also, strangely, thinks that threads posted on just over a day ago were last posted on last week (small banner just off the bottom of your screen shot). Brian.
  4. I’m sure Jim would be pleased knowing that you have taken the time to find new homes for his engines Stu. Too often the families of deceased modellers seem only too willing to consign models and engines to the skip. Such a shame. Brian.
  5. Hi Richard, Yes clearly a fairly recent addition. and stuck on where a space could be found. That label can only be a couple of inches high, so at quarter scale half an inch or so. I don't think anyone will be reading it! That's assuming that it can be printed at that size. Even the youngest Tiger Moths are now in their eighties, and will have seen a lot of changes over those years; probably numerous owners, several rebuilds and modifications. Some have likely been rebuilt from the remains of several others. There probably aren't two that are alike now. There would have been differences from new as well, with them being built at different locations and even in different countries. Brian.
  6. Richard, The signage varies between different aircraft, so to be accurate you would have to look at the particular one that you are modelling. From the couple of pictures I have of these signs, the top one is almost right (NO should read NOT, and the ends are more rounded). It is bare aluminium coloured. The bottom one is similar; the word SECTIONS reads FACTORS, and LIMITED reads PERMITTED. Also ACROBATICS reads AEROBATICS. The SMOKING PROHIBITED wording isn't on the same sign, and all of the wording is in three lines, not four, with the breaks after LOAD and CARE. This sign is mounted directly above the compass, and is white with a thin black border around the wording. Brian.
  7. Model Technics Laser 5 fuel is now made by Optifuel (but still branded as Model Technics). It’s available from many model shops, their is a map showing stockists on the Optifuel website. If delivery is required, Model Shop Leeds had it, either singles or in boxes of four. Whoever can supply Optimix should be able to supply Laser 5 as well. Be careful not to buy the low oil version by mistake. The oil used is different now, and it’s red rather than purple, but if anything seems better than the old stuff. Sadly the price has just increased, though it does come as 5 litres, so more than a gallon. Brian.
  8. RCM&E used to cover boats, cars etc. as well as aircraft, so your barge thread isn't out of place at all Geoff. It's good to see something a bit different. Coincidentally, I was watching a couple of these only last Saturday in Maldon, Essex, giving pleasure trips. Not under sail, but engine powered. Brian.
  9. I think several of the previous posts have hit the nail(s) on the head. I used to buy RCM&E every month, and Radio Modeller, and RCMW. That was back in the ‘90s and early 2000s. Since then, sadly, information available freely on the internet makes much of what was previously only available in the mags redundant, and only RCM&E remains. I do still buy RCM&E on occasion, but only after looking at one on the shelf first and if it looks to be of interest. Unfortunately that happens a lot less now, as so few outlets have it on the shelf. Two Tescos that I use that used to keep it no longer do, and WH Smiths stocking seems variable too. I do hope that RCM&E does continue for as long as it is able. It must be very difficult for the publisher to get content that is of interest to a sufficient audience. Brian.
  10. When the problem occurs, try lowering the nose of the model, hold the fuselage at say 45 degrees. This will put the remaining fuel above the carb level again. If the problem then goes away, or at least markedly improves, that will prove that it is the head of the fuel that is the cause. If it’s still the same, then it could be that the mixture is weakening as the engine heats up during a run. Alternatively, quickly refilling and restarting would give a similar indication. It could be that the carb has a slight air leak between the barrel and the body, the effect of which would become more significant as the fuel level drops. That would also be borne out by your difficulty in priming with a partially full tank, due to the poor suction that an air leak would cause. Brian.
  11. That is exactly what I would have tried as well, eliminating the transmitter setup from the equation. Reading the manual for your receiver, it makes mention of the channel 1 (throttle) port being a ‘smart throttle’ port, which if connected to a suitable Spektrum ESC received data back from the ESC for telemetry purposes. I’m assuming your ESC isn’t one of these Spektrum types? That being the case, it could be that port 1 is somehow getting locked into the wrong state at power up, and isn’t outputting any pulses to the ESC. As ch1 works with a normal servo connected, perhaps you could try Y-leading a servo and the ESC together into port 1 and see what happens (just to prove a point). Perhaps try both methods of powering the RX (via the ESC and using a battery, but not both at the same time). Brian.
  12. Yes Old Warden. Free to view from the paddocks, ticket required to get close-up or to go into the hangars, unless you are an SVAS member (or OWMAC). https://www.shuttleworth.org/product/de-havilland-weekend/ Brian.
  13. Well that accounts for the increase in the price Ron has seen compared to when I bought some a month ago. Exactly 15%. Brian.
  14. This year’s Moth fly-in is this coming weekend. Hoping to be there on Sunday. Brian.
  15. I bought a box of four ‘standard oil’ Laser fuel from MSL exactly a month ago, price £99.99 plus delivery. Today’s price is £115.16 plus delivery. That’s an increase of 15% in one jump. Both low oil and standard are the same price. I’m not sure that it’s true that the Laser fuel price has increased that much more than the other MT or Optifuel branded fuels, I think it depends on when the before and after prices are taken, as they seem to increase in price at different times. Perhaps when a new batch is produced? Brian.
  16. Thank you Richard for all of the information and photos. I will make a note of it all for when I need to make a pair of the spreader bars. I made some previously for a smaller (1/6 scale) Tiger Moth but they were simply 1/8” dowel with fine radial cuts into which the (non-functional) rigging wires were a tight fit. They looked ok but yours are much more scale. Brian.
  17. Thanks Manish, Yes they are the things. Thanks for the link, I can see now how they are made. I’ll look at the rest of Peter’s build thread later. Brian.
  18. Lovely model Richard. There are two kinds of inkjet printable waterslide decal paper, with either a white or clear base. As inkjet printers can’t print white use the former for anything that contains white (eg RAF roundels). Use the clear base if there is no white in the decal, such as your DH strut logos. Mind you, part of the DH logos were I think gold in colour, which inkjet printers can’t do either. So some compromise is necessary. Could you provide a bit of detail on how you made the separators that hold the rigging wires apart where they cross between the wings please? The (roughly) horizontal javenin-shaped things… I’ve no idea what their correct name is. Brian.
  19. As both of your ESCs were connected to the same receiver channel using a Y lead, I can’t see how even a faulty receiver could send a different signal to one of them compared to the other. Clearly your replacement receiver seems to have corrected the issue however. Brian.
  20. It also might be worth trying a separate receiver battery, and removing the red wires from both ESCs, in case the elevator / aileron servo operation is somehow disturbing the BEC output. Brian.
  21. If all of the servo connectors are used, just connect one of the servos via a Y lead. That will give you a spare connector for the battery. Brian.
  22. Perhaps they were originally for the servos (throttles, U/C etc) but have been replaced, due to some problem being experienced, by the twisted servo cables. The twisted ones do look like they could have been installed later, going by the hacked-out slot that they go into. Brian.
  23. Sounds like something hiccupped in the microprocessor. Unplugging and re-powering has reset it. Brian.
  24. Robert, I just had another thought... In cycle mode (discharge then charge), when the charger senses that the battery has reached its discharged state (determined by the 1.0V per cell setting, so 4.0V in this case), it goes into a 'rest' mode before starting to recharge the battery. The rest time is adjustable, I can't see any mention of what the default value is in the manual, but probably something like 5 or 10 minutes. During this time, the battery voltage will rise as the battery is no longer connected to the load. The manual isn't specific, but as the charging part of the cycle hasn't yet started, the display may well still indicate that the discharge part of the cycle is still active (the flashing D). If this were the case the actual current reading should be zero at this time. In discharge only mode (not cycle), when the end point is reached the charger display shows a suitable message and beeps. I know this wouldn't account for the damage to the second battery, but it's something else to investigate. Brian.
  25. I forgot to ask you Robert; you mentioned that the charger is over a year old. Have you only just recently started using it on NiMH batteries? Or have you done so for the past year without any apparent problems until now? When you make your test measurements, if you have sufficient equipment it would be useful to measure the battery voltage at the same time as the current, just to make sure that it does actually increase, and it's not something within the charger showing something that isn't really happening. Frank's findings and conclusions seem feesible. It would be interesting to see what happens with the Radient pack if the discharge were stopped once the voltage had risen slightly, then restarted shortly afterwards (ie with the cells still slightly warmed from the first discharge). Brian.
