Tim Mackey Posted November 19, 2010 Share Posted November 19, 2010 We often get folk complaining that their radio has "lost bind", or is refusing to connect correctly after switching on and so on. In many cases this could be simply down to the normal delay after switching on the tx, whilst it acquires its free channels - if you power up the Rx before its had chance to do this, funny things can happen With the Spektrum radio system, "brown outs" ( the onboard radio power supply has "dipped" below the minimum threshold ) show up as a flashing LED and this is sometimes confused with a similar flashing of the LED which correctly occurs when initially binding the Rx and Tx. This should NOT be confused with a loss of signal, which may or may not happen in certain conditions - such as flying a park fly range receiver too far away, poor installation technique - or perhaps a low Tx battery etc. I have done a short video showing both situations - correct binding of a Spektrum Rx unit, and.....a demonstration of the brown out indicator - the video for which is below. As explained in the preceding video ( "binding" ) I used one of the "Orange" clone receivers - however the procedure is exactly the same as with a genuine spekky job The "Binding" video is over HERE Edited By Tim Mackey - Administrator on 19/11/2010 14:18:50 Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted November 19, 2010 Share Posted November 19, 2010 Erm, that's not a Spektrum radio system, is it? It looks like one of the orange "compatible" receivers. Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted November 19, 2010 Author Share Posted November 19, 2010 Yes Leccy, your correct - I did explain in the "binding" video which sort of precedes this, that yes, its the "orange" clone of the spekky receiver - however the procedure is exactly the same Edited By Tim Mackey - Administrator on 19/11/2010 13:52:22 Quote Link to comment Share on other sites More sharing options...
Terry Walters Posted November 19, 2010 Share Posted November 19, 2010 Thanks Timbo - I knew most of it but seeing you do it clears up some of the doubts. Job well done. Terry Quote Link to comment Share on other sites More sharing options...

Tim Mackey Posted November 19, 2010 Author Share Posted November 19, 2010 I have edited the video now to explain my use of the clone rx - cheers for the heads up. Quote Link to comment Share on other sites More sharing options...

robert chamberlain Posted May 24, 2018 Share Posted May 24, 2018 Hello,----- It has been suggested I go to a 5 cell receiver batt pack to avoid voltage drops due to a temporary high servo load. Am I correct in that this would cause the rec to brown out and shut down for a second? If so, would it re-set quickly? How quickly? Am I on the right track with this?-------Thanks in advance,----Bob C Quote Link to comment Share on other sites More sharing options...

Cuban8 Posted May 24, 2018 Share Posted May 24, 2018 A five cell RX pack will do you no good if it's constructed from batteries with a poor C rating i.e so called 'high capacity' AAs (sometimes as bad as 1C for a certain 2200mA size that I've tested) . If the pack can only deliver 2A, before collapsing, whether 4 or 5 cells, then that's all you're going to get and if your servos at any time need 3A, then you'll be in bother - no matter what brand of radio you use. Nimh RX packs never seem to come marked with their C rating, so the user is guessing as to whether the battery is going to be sufficient, you wouldn't normally guess about the performance of your Lipos/motor/engine/strength of airframe etc, so why take a chance with the performance of certain receiver batteries? Be honest, do you know how much current the RX batteries in your models can safely supply and what the worst case scenario for current drain from your models is? Would you know how to check?
