Denis Watkins Posted December 22, 2019 Share Posted December 22, 2019 1st Check Battery voltage on screen. What is it reading And In the monitor window observe the stylus triangles move Move all sticks and switches In all directions slowly to confirm they operate end to end Edited By Denis Watkins on 22/12/2019 09:09:36 Quote Link to comment Share on other sites More sharing options...
Trevor Posted December 22, 2019 Share Posted December 22, 2019 Is there a throttle lock switch somewhere which is inhibiting the throttle channel? As Denis says, the servo monitor screen is your friend! Quote Link to comment Share on other sites More sharing options...
Trevor Grace 1 Posted December 22, 2019 Author Share Posted December 22, 2019 Hi Denis,voltage reading 10.3 all sticks inc. throttle stylus have got full travel. now refuseing to work new receiver full stop.. Quote Link to comment Share on other sites More sharing options...
Colin Carpenter Posted December 22, 2019 Share Posted December 22, 2019 Trevor. Are the orange bars on on face lit up ? These indicate the RF board is transmiting . If not , the boards gone west and nowt will work. RF boards were a known Spekkie problem years ago. Colin Quote Link to comment Share on other sites More sharing options...
Trevor Grace 1 Posted December 22, 2019 Author Share Posted December 22, 2019 not sure what orange bars your talking about !!!!!! never seen any! Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted December 22, 2019 Share Posted December 22, 2019 Can you get the model number off the back of the DX7 Trevor, Is it SPM7000 Quote Link to comment Share on other sites More sharing options...
Colin Carpenter Posted December 22, 2019 Share Posted December 22, 2019 Do you have a DX 7 black version or the older JR looking tx ? The newer versions have vertical orange lit bars above neck strap clip indicating RF being transmitted ! Not sure about the older version I'm afraid !

Martin_K Posted December 22, 2019 Share Posted December 22, 2019 The vertical bars central between the gimbals. I had always taken those as simply a power supply indicator? (2 more posts appeared while I was typing, sorry if this confuses matters). Edited By Martin_K on 22/12/2019 14:45:22 Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted December 22, 2019 Share Posted December 22, 2019 Keep going lads, we have all twigged, it could be a DSMX / DSM2 issue As 10.3v does suggest a G1 DSM2 Tx Edited By Denis Watkins on 22/12/2019 15:22:45 Quote Link to comment Share on other sites More sharing options...
Colin Carpenter Posted December 22, 2019 Share Posted December 22, 2019 Yes ! Those five vertical bars when lit indicate RF is transmiting ! No lights no work ! Simples !!😁😁 Not enough knowledge of JR type tx I'm afraid ! 😟😟. Colin Quote Link to comment Share on other sites More sharing options...
Trevor Grace 1 Posted December 22, 2019 Author Share Posted December 22, 2019 Hi Dennis, def got DSM2 on the front +plus found a date on the box 2007 Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted December 22, 2019 Share Posted December 22, 2019 Right Trevor, many recent Rx are DSMX Which don't work on DSM2 BRCHobbies have a good range of DSM2 Receivers for your DX7 As early DX7 were DSM2 only Quote Link to comment Share on other sites More sharing options...

Frank Skilbeck Posted December 22, 2019 Share Posted December 22, 2019 Posted by Denis Watkins on 22/12/2019 16:09:16: Right Trevor, many recent Rx are DSMX Which don't work on DSM2 BRCHobbies have a good range of DSM2 Receivers for your DX7 As early DX7 were DSM2 only I thought a DSMx Rx would work with a DSM2 transmitter but not the other way round. I have got an early DSM2 only Dx6i and have bound it to several DSMx receivers with no issues. Note these are all non-telemetry types so that may not apply to telemetry receivers. Just one other thing, if you've bound the receivers in one model memory and then changed to another model memory they won't work, model match on Spektrum binds the receiver to specific model memories, if you wish to reuse a receiver on a different model memory then you have to rebind it to that model memory.

Shaun Walsh Posted December 22, 2019 Share Posted December 22, 2019 What receiver is it? Is it the Spektrum AR620 which I believe has an input marked BATT but the input you need for throttle is marked 1.The BATT input is for the connection of an external BEC (not an ESC) and supplies power and everything but the throttle will work, attach the ESC lead to 1 and you should get the throttle function to work too.

Trevor Grace 1 Posted December 23, 2019 Author Share Posted December 23, 2019 Hi everyone, Thanks to you all for you help and and answers. Especially to Denis Watkins. After a long time out of flying i thought any DSM Rx was ok. Have now dug up an old DSM2 and it went straight in. LESSON LEARNT thanks to a great forum. Merry Xmas all, Trev.

Roger Price 1 Posted December 23, 2019 Share Posted December 23, 2019 I second Trevor's remark about what a great forum this is. The wealth of knowledge of those who are prepared to help other modellers solve a problem is praiseworthy indeed. It is akin to a healthy club environment where if you need help someone is always willing to assist. Despite having 50 years in this hobby I learn something new each week. Long live this forum.

They do take a few seconds longer to link though. As I understand things Spektrum Dsmx RXs are backward compatible with old DSM2 TXs but your old DSM2 RXs are useless with DSMX only trannies.

Trevor Grace 1 Posted December 23, 2019 Author Share Posted December 23, 2019 What is SBUS ???? Quote Link to comment Share on other sites More sharing options...
Don Fry Posted December 23, 2019 Share Posted December 23, 2019 A method of daisy chaining servos, with a decoder in the system, that sorts out what servo extracts information from the daisy chain. Think, one plug into the receiver, one wire to the wing, loads of servos in the wing, or one wire to the back, multiple sevoes back there. Sometimes the decoder is in the servo, so you just daisy chain them off one receiver plug. So endeth my knowledge base. Welcome to the new tech learning curve. If you are interested, there is a (database, thread?) on this site, somewhere, a glossary of modern terms. Quote Link to comment Share on other sites More sharing options...
