  1. Good one John M. Following the RM Plan numbering sequence I found It appeared in the June 1981 edition of Radio Modeller. Unfortunately I don't have that magazine in my collection but there is a copy on eBay.
  2. My guess - and it is purely a guess - is that it is a one off. Perhaps it may have been inspired by Ken Bink's Suzy Que for the same distinctive nose and Chris Foss's Centiphase for the tail?
  3. Have you got a servo tester? If so then it will be easy to check for centralisation & throws by plugging each in turn, or together if the tester has multiple outlets (or use Y leads).
  4. That looks like it may be caused by moisture condensation, it's vulnerable to this if you put your transmitter on the ground between flights, or keep it where there are large temperature fluctuations . I keep my Tx's indoors & use one of these on the field to avoid the issue:
  5. @Phil Green should be along sometime. If anyone can get a lead on it my money would be on Phil.😀
  6. Als' Hobbies are good and are an approved Service Centre. One alternative is to use LogicRC who are the UK Spektrum distributors and have their own Service Centre: https://www.logicrc.com/default.aspx?s=c:0, ,c:ZZ-Support,c:ZZ-SpekSup The other is Mike Ridley who is freelance & has an unblemished reputation: https://modelradioworkshop.co.uk/
  7. Watch the Solarfilm Video! Made many years ago by Derek Hardman the manufacturer of Solarfilm and released as a VHS tape, it is just as relevant today with Oracover. Some kind soul has uploaded it to YouTube for the benefit of later generations. It will give you a really good foundation knowledge. Part 1 shows how to apply Solarfilm and how to cover a wing tip with one piece. Part 2 shows how to do a special effects including chequered effects, roundels etc. Part 1 finishes at approx 33 mins and Part 2 starts just after 40 mins.
  8. +1 for Flytron. Their high intensity strobes look great at dusk but do little or nothing to help during the day. Their is no substitute for good vision & flying within your visual range.
  9. My Fusion 360 won't open today either & I'm using he latest Mac OS
  10. Too late for you now Simon but for others we had the same problem with half a dozen aircraft from a deceased member's estate that had been stored for some time. Bathroom/Kitchen surface cleaner in the form of trigger spray bottles & wet wipes were very effective & did not damage the finish. Before & afters:
  11. The safety sheet for their 30 min finishing resin states ’6. Sets in 30 minutes at room temperature (77F or 25C) with full cure in 24 hours. Note - For cooler. temperatures, setting time may be longer.’ Apparently US room temperature is a bit warmer than those the UK!
  12. Best wishes for an early & full recovery Matty
  13. I've still got a Hitec Powermate II which was a popular battery checker before LiPos came into common use. That puts a load of 0.6amp at the 4.8v setting & 0.8amp at the 6volt setting. Futaba produced the BR-2000 checker at the time which also could load up the battery.
  14. You can certainly mix and match analogue & digital servos. But if you do so you cannot take advantage of the digital servos ability to accept a higher frame rate, the whole system must operate to the lowest common denominator otherwise you may burn out the analogue servos. That means in practice for mixed digital/analogue servos the frame rate must be left at the default 22ms for Spektrum (or 17ms for Jeti, those are the 2 brands I am familiar with) rather than a faster rate being selected under the 'Frame rate' options in the menu.
  15. 30amps-ish Well, 29.6amps on my Acro-Wot foam-e according to the telemetry (Jeti Mui-50 sensor) and I believe that has the same powertrain as the Wot4 & Wots-Wot
  16. It looks like the answer is - neither! Rather I suggest you use the Item - Value parameters as shown in the SkyWalker ESC instructions which vary from both of the stickers:
  17. There were a number of 3D printed aircraft at the RCHotel last year. Joe Anderson was having great success with lightweight & flexible filaments. I was quite impressed with them, certainly a much more viable medium than conventional PLA. I was able to fly the ones below whilst I was there and performance is certainly comparable to conventional constructed models.
  18. I seem to recall that Probuild-UK imported & sold those JR 9303 radios in about 2010-2012. They stated that they were imported directly from Japan, not via the USA, and were to UK specs. I looked at them at the time but in the end bought a McGregor imported DSX9 to replace my PCM9X.
  19. I've built the RBC Tiger Moth which is that size & used the power train from one of the Chris Foss Foamy Wots that I had lying about, it is more than enough & I never use full power. If you look at the RBC kits specs Link and that of the DB Sport & Scale version which is the same size Link it should give you a good idea, but I found the set up is not critical.
  20. And according to Panasonic, makers of the Enerloop NiMh batteries: "We've improved the metal-hydride alloy lattice inside your eneloop battery so that it retains 70%* capacity even after 10 years in storage. The design also resists voltage drop during discharge and minimizes loss of capacity. Once charged, you can trust eneloop to work just like a dry battery, and its long storage life is great in emergencies. * Capacity based on testing method established by IEC 61951-2 (7.3.2) when stored at 20 °C (based on Panasonic's estimation) and compared with minimum capacity. Varies according to conditions of use." The Enerloop pack I use for setting up models on the bench was bought 14 years ago retains its capacity & gets charged maybe once a year. Whilst I use LiPo's or LiFe's in most of my models quality NiMh's tend to be my 'go to' for slope soarers and are still a viable option in many cases.
  21. I've also been hit. A few pence for JetFrog was spotted by my bank (NatWest) who immediately blocked the transaction and my card. I sorted it out with them today & a new card is on the way. In common with many others I'm a Nexus customer.
  22. Here's an advert for the 'Jim' range from June 1978 RCM&E:
  23. Whichever Toolkit or ISDT best suits your needs, you won’t go far wrong with either
  24. As has already been pointed out you can check you CAA registration status on the CAA website, whether you pay them directly or via the BMFA: https://register-drones.caa.co.uk/my-registration
