  1. Martin, I've done that as well previously with no problems. Just make sure you set one Tx to "Transmit" in the transfer screen and the other Tx to "Receive " in its transfer screen. This step is easily missed. Pages 20&21 of the manual explain it but not as clearly as could be.
  2. Strange. I recently copied 8 models between two JR DSX9 Txs and everything copied perfectly including all servo directions, sub trims, mixes etc.
  3. I'm going to disagree. There is no convention. Most combo's would be provided with some c/w servos and some anti c/w to enable the most appropriate to be used in a particular installation. Just imagine the following scenario: servo mounted in the left side of the tail end of a/c connected to elevator horn on the underside of surface. If the servo link is made from the " top" of the output disc then for up elevator the servo must rotate c/w. Put the same servo in the other side of the fuselage and the situation is reversed and the output must be from the "bottom" of the disc for up elevator or use a reverse direction servo .What convention would you use?
  4. There are no "conventional" or "normal" orientations of servo mounting. If you decide to connect the moving surface to one side of the servo arm or the other side (i.e. @ 180 deg.) you may have to reverse the servo direction in order to get correct surface direction. No manufacturer can forecast ( guess) which side you will use.
  5. Martin, Cascmite is a casein based glue (made from milk) and is a powder mixed with water. No acid involved. Maybe you're thinking of Aerodux.
  6. Lighter fluid (NOT gas) works very well. It's pure naphtha.
  7. Re the 347. Didn't that model of Tx require the sticks to be calibrated if the main battery was left to discharge completely? The calibration method was detailed in the manual and was very easy to do. The pc board lithium button cell retained all settings including calibration. It's worth a call to Mike Ridley at Model Radio Workshop (07708 0436163). If he can't help, nobody can!   Edited By jrman on 06/11/2018 12:14:39
  8. I understand what a soft switch is, I just thought you were adding another switch as well.
  9. Martin, "but although soft switches have a remote switch" Not sure what this means.
  10. Finished. Obviously the numbering has changed from the BMFA version but it was an excellent "crib" sheet. Well done .
  11. Are we all going to wear red carnations and carry a copy of The Times so we can recognise each other?
  12. That's just as bad!! Quit while you're ahead.   Edited By jrman on 14/08/2018 18:21:08 Edited By jrman on 14/08/2018 18:21:59
  13. Cymaz, that sounds like a serious medical complaint.
  14. British rather than Dutch or French roundels? Edited By jrman on 13/08/2018 11:40:26

    Exess fuel

    Steve, Try "Oz Kleen Carpet Power". Robert Dyas stock it. As it says on the bottle "This product actually works"
  16. No. The weight would increase by the cube of the linear enlargement i.e. 1.5x1.5x1.5 = 3.375. (all other things being equal)
  17. Cyano is sometimes reluctant to give a good bond to spruce but can be improved by rubbing baking soda on to the joint before introducing the cyano.

    Valve work

    My understanding (on OS's at least) is that the valve seat has a sharp edge and is not chamfered like a car engines valve seat. Grinding does little to solve the leak.
  19. I would boil ( about 5 minutes) the old nylon props to restore their moisture content before using them.
  20. Try Hobby Plastic.( MacGregor) https://www.hobbyplastic.co.uk/index.php?main_page=index&cPath=63_338_341&zenid=j2vs8a6cv9j1c9du776a9hhhe2
  21. Look on the BMFA Club finder page for contact numbers of Southend Radio flying club and South Essex Model Aircraft society both of whom fly at Two Tree Island.
  22. I'm intrigued Peter. It wasn't me but what was "I" doing?
