  1. FlyinFlynn if you are UK based would you be interested in selling some pcb boards to offset your costs ? I'm a complete numpty when it comes getting circuit boards done , last lot I ordered ended in the bin.
  2. Thanks everyone something to get me interested putting the E back into RCME . I copied completely a GPS/Arduino data logger with SD card from the internet and made a couple for lads at my club with just a few alterations to the code to display speed etc . The format of the output isn't right to display on Google but I will have a look at the code above and see if I can work it out . I've got an homemade Arduino Frsky GPS logger I got that to display in the Frsky suite the location and height data. The SD card version just displays location,height,speed and time which is all the CAA want for +25Kg models I think . Nice to know someone else is tinkering and getting results .
  3. Still slow 5 minutes this Sunday before it let me in !
  4. I've still got a works issued Fluke with a calibration sticker dated around late 90s which works fine except the case is araldited together and has tape around the case ( hard life) .
  5. Could be Mr Putin , funny how you forget one war when another kicks off ( Gaza).
  6. Maybe the CO will rotate to a new posting next year ?
  7. I've noticed that not many fliers have the old Nimh tester that puts a load on and displays on leds - good or bad. I rummaged around and used a cheap voltage display ( 3-30+ volts) and a switch that puts a 20ohm load across the battery . This gives a current of about 300mA on 6v and 250mAh on 4.8v a good load . What would you think an acceptable voltage drop at that current draw should be ? I was thinking no more than 0.2 to 0.3 volt drop on a fully charged battery , anyone else got any thoughts ?
  8. Another for the Cox Stuka control liner when I was 12 about 1970 , should really have had a helper to fly as the inevitable happened and it didn't survive .
  9. Does anyone know for sure I'd the Tundra wing struts are structural , the wing is pretty stiff without ? The reason my friend dumped one in a tree yesterday we got it back but the strut has torn a hole in the wing where the fastening used to be . Anyone used one without ? It's 2nd hand and little tatty so no great loss if it claps ! That's the smaller Tundra not the Grand Tundra .
  10. Little more specific but the Amateur Radio courses run by clubs would be a good start , there are 3 levels and give a good grounding in electronics . Plenty of clubs running the courses and providing help . My personal introduction no longer exists 3 years of Nautical College leading to Radio Officers ticket , very in depth course but things have moved on since the 70s.
  11. Has anyone got a figure for a DLE20cc on a Menz 17x8 wooden prop , I'm getting 7000rpm is this about right ?
  12. Hi, I fired up openXsensor and built up an Arduino Nano with BMP280 module , all worked fine after the I2C address was corrected to 0x76 not 0x77 . When I tested the module I got its I2C address I got Vspd , Alt and temperature but on my Frsky TXs I can only see Vspd and Alt not temperature . How do I add the temp as well to the data ? is it easy or a bit of a faff . Can't seem to find any info on this . Cheers in advance
  13. dinosaur here , upgraded to Win11 and when it was all installed downloaded the program "Classic Windows" and made it look like Win7 -happy bunny !. Loath the Win10/11 interface awful to use and loaded with stuff i don't want or use , give me Win7 anyday .
  14. I've been down the Apprentice route as a beginner and only felt really in control when I swopped out the AS3X Rx for a standard one . I was not the only one to find that either the Apprentice is a really forgiving beast anyway , nicer to fly with a normal receiver anyway . It doesn't bite or stall unless your really inept and I've often wondered why it had AS3X in the first place .
  15. Another nod for e.calc , always found it reasonably accurate when checked with a power meter . Very good for fine tuning I.e. balancing current/wattage/prop size .
  16. Here's a rather weird problem with a QX7S Access TX and my Windows 10 desktop. Whenever the USB is plugged in the tx asks is it a joystick or storage , OK so far . If you select storage it says it can't find a driver because its unrecognised , a common problem but messing with drivers didn't help . Tried changing cables to no avail but one common thing was the USB extension lead from PC to my desktop , now this extension is fine with my external hard drive and other USB items . I tried it without and it worked perfectly plugged right into PC , so much for Amazon USB extension leads , not faulty all the time just under certain conditions . Weird and an absolute time waster of an exercise.
  17. Good film , just a pity about the Landrover (not made until 1948) and BF108s masqueraded as BF109s and some of aerial scenes were obvious models . Otherwise a pretty good film .
  18. Anyone selling a QX7 or QX7S Access transmitter , maybe upgrading ? Preferably working but would take non working if complete . Cash waiting for right radio , can collect within reasonable radius of Manchester . Brian
  19. Boxing it up for return to Logic RC just now , last time they had it back within 3 days FOC can't hope for that this time . Maybe mine had a bad batch of trim switches I assume they are all the same ones .
  20. Hi Has anyone experienced failure of the trim switches on this radio , my rudder trim (mode 2) has failed the switch is all wobbly inside . This radio has been away twice already and had firstly the aileron/elevator pair replaced and lastly I asked for all 4 to be replaced after yet another failure . Its lives in a nice cut out box with stick protectors and isn't abused at all , as for the rudder trim can't remember last time I touched it apart from a new model setup . This seems a high failure rate for 4 year old radio to me , anyone had the same ?
  21. I'll fit it and monitor the fades , if sensible I'll leave it .
  22. Hi all , I have used the AR410 in electric models before with a good record but never in an IC plane - any issues ? Having to replace because the venerable Orange RX with satellite needs re- binding every time I fly it 4 times on the trot now . I always wrap the RX in foam anyway but wondered has anyone any issues ? . It's in an elderly Boomerang with a Saito 62 but it is one of my all time favourite airplane combination , so easy to fly even forgives dumb thumbs and clumsy moments.
  23. Hi, We had a new club member turn up with 2 brand new DX6e transmitters and a nice Boomerang trainer complete with Irvine 52 , he had buddied up the DX6e to each other ready for a bit of supervised flying but the future plan was to fly with his grandson ( good idea). We started and tuned the Irvine and tested the controls all went the same way , all good . As it was a bit busy with one of our tame lunatic " throttle don't use them" fliers hooning around at 100mph everything was switched off for 10 minutes and when switched on again the student TX had lost its bind . Rebound everything looked OK and the flight went well but after being switched off again the student became unbound , thinking something odd we tried to bind but no joy so we swapped the TX around so the other was the master but still no joy binding them despite standing 15 feet away shielding the TX with your body ( known speccy problem) . A DX8 was pressed into master service and one the DX6e tried to bind under trainer again but "bind failed" so another DX8 was used as student and all was well . At no point did the DX6e lose bind to the aeroplane just each other in trainer mode , we have a regular flier whose uses a DX8e as master every week with no problems and finally both DX6e are up to date software versions - so anyone any ideas why ? Thanks in anticipation.
  24. Don't forget that Spectrums have an excellent wireless buddy box facility as well , rather makes a cable redundant .
  25. As I suspected pro's and hams as I am . My career started when a car telephone was a roughly 45x30x15cm box that went into your car boot and you worked it from a little control box on the dash and you called the operator to dial the number , today it sits in your shirt pocket . Just as in modelling electronics it got smaller every generation and more complex until by the time cellular came along we didn't open them anymore just sent them to a specialist workshop . We use 2.4Ghz for our models the highest I ever worked on was 1.5/1.6 Ghz analog microwave systems for the water industry in the North East , a few watts of that went a long way but they were very directional and gainy aerials .
