Andy Fox Posted September 4, 2016 Share Posted September 4, 2016 I've got an Eflite UMX B17 with a weird issue.... the auto stabilisation for the ailerons is reversed. Elevator and rudder are fine, but not the ailerons. Makes for some interesting flying. Anyone know how to resolve this?

Chris Barlow Posted September 4, 2016 Share Posted September 4, 2016 What tx are you using and did you reverse the ailerons after binding? Quote Link to comment Share on other sites More sharing options...
Andy Fox Posted September 4, 2016 Author Share Posted September 4, 2016 I'm using a DX6i, have tried reversing after binding and before - if that makes sense ... Quote Link to comment Share on other sites More sharing options...
Robert Putley 1 Posted September 4, 2016 Share Posted September 4, 2016 Very strange. Be interested to see what caused the problem. Quote Link to comment Share on other sites More sharing options...
Bob Burton Posted September 4, 2016 Share Posted September 4, 2016 Andy - I have a Spektrum AS3X programmer (SPMA3060) which may be able to reverse the aileron stabilisation on your B17. It is a few years old and I originally bought it to program an AS3X Sbach as I wanted to be able to turn the AS3X on and off, which I did. Subsequently I used it to change the stabilisation on a foamie into which the Sbach electrics had been transplanted. I have no idea whether it is compatible with your model or can do what you want, but if you do some research online and would like to give it a try then let me know and I will pop it in the post so that you can give it a go.

Denis Watkins Posted September 4, 2016 Share Posted September 4, 2016 You can reverse servos on the mobile phone app Andy Downloadable from Horizon Hobby Quote Link to comment Share on other sites More sharing options...
Andy Fox Posted September 4, 2016 Author Share Posted September 4, 2016 Thanks Bob, thats a kind offer. Reading the manual for the programmer it does support the SPMAS6410 Rx used in the B17 - so hopefully would resolve the issue. Can I take you up on that offer? @Dennis, looked at the app and it seems to only support the latest receivers - would be an easy fix if I could utilise it... Thanks for the replies guys Andy Quote Link to comment Share on other sites More sharing options...

Bob Burton Posted September 5, 2016 Share Posted September 5, 2016 It's in the post. Keep it as long as you need before returning it (return address on the envelope) or make me an offer. Bob Quote Link to comment Share on other sites More sharing options...
simon barr Posted September 5, 2016 Share Posted September 5, 2016 Blimey, Andy, I thought that would be an easy fix......... Quote Link to comment Share on other sites More sharing options...
Andy Fox Posted September 5, 2016 Author Share Posted September 5, 2016 yeah - thing is I can't remember if it was right to begin with. I'm suspecting not .... I've tried rebinding with a new model memory - reversing servos before and after binding - binding while model upside down and all combinations in between, but no joy!! Many thanks Bob - you're a star! Quote Link to comment Share on other sites More sharing options...
Stuphedd Posted September 5, 2016 Share Posted September 5, 2016 Are those Speccy leads, the phone and the computer ones worth while ?? The programming with the TX sticks is a bit "of a pain " , I have managed so far , only just , not crashed yet , but its only a matter of time , and my programming skills are pretty non existant and so far have resisted buying a lead as they are not the cheapest thing on my priority list !! advice would be very welcome please. pete Quote Link to comment Share on other sites More sharing options...
Bob Burton Posted September 5, 2016 Share Posted September 5, 2016 I would not have bought the lead had I not seen it lurking in the display cabinet of the LMS. Was/is it worthwhile ? Well, it did the job that I wanted, but unless you have a large fleet of AS3X models it is of limited use. I used it, experimented with it a bit, set the model the way I wanted then put it in the drawer where it has languished for a couple (or more) years. I only remembered that I had it when the query arose which is why I am happy to loan it out or pass it on to anyone who needs it. Quote Link to comment Share on other sites More sharing options...
Stuphedd Posted September 5, 2016 Share Posted September 5, 2016 cheers Bob, can I be added to the list of borrowers ?? cheers Pete W Quote Link to comment Share on other sites More sharing options...
Bob Burton Posted September 6, 2016 Share Posted September 6, 2016 Pete When Andy has finished with it I am quite happy for him to pass it on to you to try/use/buy as appropriate. Just let me know where it is. Bob Quote Link to comment Share on other sites More sharing options...
Stuphedd Posted September 6, 2016 Share Posted September 6, 2016 Thanks Bob, Keep me informed as to if/when its availiable . all the best Pete W Quote Link to comment Share on other sites More sharing options...
Bob Burton Posted September 6, 2016 Share Posted September 6, 2016 Pete Keep an eye on this thread and you will know when/if it becomes available. If Andy decides not to make me an offer for it then it makes sense for him to send it to you directly to you. Perhaps I should ask for photographs of it in unusual places like some gnomes !

Peter Christy Posted September 6, 2016 Share Posted September 6, 2016 As a follow on to this thread, I have one of the little UMX Pitts Specials. Terrific fun, but one day, the elevator reversed itself between sessions! Not only was the elevator function reversed, but so was the gyro sense, indicating a receiver or servo fault. I discovered this when , after a couple of abortive take-off attempts, which I put down to the grass being too long, a hand launch produced a half-loop over my head and a crash behind me! On all previous hand launches it had gone off as straight as an arrow! As I say, because the gyro sense was also reversed, it cannot have been a transmitter issue - and the transmitter (JR DSX-9) hadn't been touched between sessions anyway! Horizon replaced the model FoC, after quite a wait due to all the stock being in Germany...... I now check and double check all control functions for direction, as well as operation, prior to launch! -- Pete Quote Link to comment Share on other sites More sharing options...
Robert Putley 1 Posted September 6, 2016 Share Posted September 6, 2016 Have been following this with interest. I also have a few USMX models, however, never suffered any pronlems. Quote Link to comment Share on other sites More sharing options...
Andy Fox Posted September 9, 2016 Author Share Posted September 9, 2016 Hi Bob - it's arrived safe & sound .... just need to figure out how to use it!! Quote Link to comment Share on other sites More sharing options...
Bob Burton Posted September 9, 2016 Share Posted September 9, 2016 Glad it made it OK. I cannot remember a thing about how to use it apart from plugging it in, downloading and installing some software and running it. Good luck ! Quote Link to comment Share on other sites More sharing options...
