Tony Harrison 2 Posted October 1, 2021 Share Posted October 1, 2021 (edited) Kit: Turnigy G25 motor (710kv/600w), 4S/3700 battery (freshly charged), Turnigy ESC Plush-60A (UBEC 3A/5V ver 3.1 DC 5.6V - 26V), Spektrum AR410 RX, Spektrum Dx6i TX. I power up the TX, connect battery, hear usual 3-tone "ready" tones - but the motor just sits there giving a single bleep every 2 seconds or so, accompanied by a tiny twitch. No response to throttle movement. Naturally I've swapped the ESC/motor leads around in various combinations, but the response is the same. The Turnigy ESC instructions show various "error" tones but not the single tone/2 secs I experience. They also talk about programming the ESC via one's TX but I can't find how to do that - not sure the Dx6i is sophisticated enough anyway. What blindingly obvious thing am I not doing? Or what might the error(s) be? I've checked the battery and it's recording 16.62V which seems healthy. Any advice gratefully received - Tony Edited October 1, 2021 by Tony Harrison 2 forgot something Quote Link to comment Share on other sites More sharing options...

Chris Walby Posted October 1, 2021 Share Posted October 1, 2021 Not the old "trim the throttle down" trick is it? You are binding it correctly, its just as a safety feature the ESC will not arm with a high (what it sees as high) throttle setting. Quote Link to comment Share on other sites More sharing options...
dan h Posted October 1, 2021 Share Posted October 1, 2021 Yep, I think Chris is right. I have experienced this in the past ad soon as the throttle trim was trimmed to zero the motor armed and worked. Quote Link to comment Share on other sites More sharing options...

Sorry Chris, I don't understand: how do I perform this "trim down" thing? rgds Tony Quote Link to comment Share on other sites More sharing options...
dan h Posted October 1, 2021 Share Posted October 1, 2021 Tony. On the transmitter. you have the 2 main sticks for controlling the plane. Beside them you have the little square trim buttons on the throttle side press the square button down a few clicks.You should hear the motor arm. Hope that makes sense Dan Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted October 1, 2021 Share Posted October 1, 2021 If all the above doesn't work for you yet, For safety, with the prop off Reverse the throttle On the Tx, and click the trim down again The motor may spring into life, so always prop off for now Quote Link to comment Share on other sites More sharing options...

Hope that makes sense Dan Ah, the trim buttons - I hadn't any idea they were relevant to anything except flying controls. Will try this and report back. rgds Tony Quote Link to comment Share on other sites More sharing options...

Tony Harrison 2 Posted October 1, 2021 Author Share Posted October 1, 2021 Chris, Dan, Denis et al - tried the trim thing, including the reverse-throttle trick, again with no result - same experience as previously. I think I'm following the advice correctly. Took the throttle trim right down to zero in stages, reversed it, - still nothing... Hmmmm.... rgds Tony Quote Link to comment Share on other sites More sharing options...

Denis Watkins Posted October 1, 2021 Share Posted October 1, 2021 (edited) We are not finished yet Tony So, maybe take a break but next job is to test the AR 410 throttle channel with a servo And 1st, we rebind the AR 410, normal throttle down, failsafe bind with a servo in channel 1 and power to BATT So we see the throttle stick move the servo proportionally in CH1 Footnote The DX6i is fully capable of doing any 6 channel job that you can imagine Edited October 1, 2021 by Denis Watkins Quote Link to comment Share on other sites More sharing options...
Brian Lambert Posted October 1, 2021 Share Posted October 1, 2021 Have we tried pluging in a servo to the throttle cannel to check the receiver is working? Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 1, 2021 Share Posted October 1, 2021 I am thinking the esc is not plugged into the throttle channel. Quote Link to comment Share on other sites More sharing options...

Brian, I pulled the receiver from another model in which it had worked fine, with very little use. And EB, yes, I tested the rig the other day, and the control servos worked fine. It was indeed just the throttle which didn't. Dan and EB, I know I had a very sound (I thought) reason for connecting the ESC into the "Battery" channel on my AR410, but I just swapped it onto Ch1** - and bingo, lift off, motor whizzing around... Which makes me feel extremely thick, and though such a daft query has wasted people's time I am very grateful for this support - and I've learned a couple of things too. Now I know the setup is fine, I can proceed to fit an extended bulkhead into this old-ish Seagull Arising Star, supplied complete to its former owner with a OS 46 2-stroke, to give the Turnigy motor proper clearance. Then it's off to see Stan Yeo for a couple of props... I know this model has been electrified by other folks, and I think this setup will work. Glad the motor's fine and I don't have to shell out for another... Again, thanks and apologies for wasting people's time when I'd made a daft mistake. Tony **Ch1 is marked something like "Data" which is confusing... 2 Quote Link to comment Share on other sites More sharing options...
dan h Posted October 1, 2021 Share Posted October 1, 2021 Tony no reason to feel thick at all and you have not wasted anybody's time. that what's this forum is all about helping each other solve problems big or small. Ive had lots of help from the guys on here so its always nice to give some help back. Glad you got it sorted. Dan 1 Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted October 1, 2021 Share Posted October 1, 2021 Tony - on the AR620 the first set of pins is for Data, the second set of pins is actually Channel 1, which is Throttle by default on Spektrum. I'm guessing that the AR410 is the same. Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted October 1, 2021 Share Posted October 1, 2021 Oh and like Dan said, no need to feel that you've wasted anyone's time with a question or a request for help. Great that you have everything working. ? Quote Link to comment Share on other sites More sharing options...
