Brushless motor not running - just beeping
If you have a problem with a electric motor that will not arm itself and beeps continuously this story might help.
I have recently decided that I wanted to try my hand at a larger electric plane. A friend of mine had framed up a 4*40 for me so I figured this was a good plane to take the plunge with. I purchased a Rimfire outrunner 42-50-800, 60 amp ESC and a 5 cell 2100 mAh battery. I got everyting into the plane, charged the battery and was ready to go. I took the plane (with no prop) out on the deck to make sure everything worked. I connected the battery, inserted the arming plug and the motor just started beeping. I worked the throttle like the directions for the ESC said and it kept on beeping. I checked all the connections and tried it again. It kept on beeping. I searched this site and didn't find anything relevant. I called the Great Planes help line and the tech said it sounded like a bad ESC and to send it back since it was still under warranty.
Luckily I lost the receipt so I had to go to my hobby shop to get a copy. While I was there I told them of my problem and they said that continuous beeping is typically a sign of the ESC not getting a signal. When I got home I checked the receiver with a servo and it was putting out a signal on channel three.
Then all of a sudden - BAM - I figured it all out. I have a Futaba 9C and I placed the new electric 4*40 in the memory where I had a glow 4*40 (victim of a midair while trying to fly in a formation with another 4*40). I checked the end points for the throttle and saw that they were at 40% low throttle and 80% high throttle, I dialed both of these to 100%, hooked up the battery and tried the motor again. It worked.
A couple of things bothered me about this. One my own stupidity for not checking the motor endpoints. The other one are that the directions for the ESC do not mention anything about continuous beeping and finaly that the technicianat Great Planes did not recognize the symptoms that I described.
Regardless, everything worked out OK and i have a great flying plane.

RE: Brushless motor not running - just beeping
Hello All
I read this post because I have a rimfire (35-36 1000) that all of a sudden began to begin beeping
I replaced the ESC with a lower amp version ( from a 45 amp to a 22 amp) and motor spun fine
so I ordered a replacement for the 45 - same problem
the 45 amp is a Electrifly SS-45 and the 22 amp is a Eflite
any other things I can try before I send my newly ordered SS-45 back for - I guess - repair ....
thank for you thoughts

RE: Brushless motor not running - just beeping
Sometimes its your throttle trim that is too high, some ESCs are sensitive so the motor will not arm itself. Sense that throttle is up.

RE: Brushless motor not running - just beeping
yep, just had the same thing happen to me. I got everthing hooked up, and it looked great. I followed the programming, but the sucker would not arm to run. I had thought that maybe it was just the trim on th radio, but it was electronically set too high to arm. as soon as I reset the throttle end points, the arming beeps occurred and i was good to go. I am now a happy camper.

RE: Brushless motor not running - just beeping
I know I'm a little late (and you solved your problem already) but I had difficulty using an SS Silver Series ESC that I couldn't get to arm. The problem was that I didn't know there was an arming procedure. Most of my experience has been with eflite stuff that requires moving to 0% throttle. But my particular small SS ESC required an arming procedure where you go to 100% then 0%, then it arms. That was trickky!

I am a total beginner, go my first RC plane a Hawk sky trainer plane a few weeks ago.
Took it out first my first fly and as expected crash a few times, after a pretty hard crash I notice that after I connect the power the motor did not run and started beeping.
Thi is a constant beep beep beep ( less than a second apart) for about 30 to 40 (some times longer) seconds after I hear one beep and then the motor will respond to the transmitter commands. Same times it takes longer. Did I damage the motor?
I connect I the rudder servo on channel 3 (Thro) and when I connect the battery the rudder moved to one side, although throttle is all the way down.
I followed some forums advice how to reset the throttle position but this did not work.
Any help and advice will be much appreciated.
I will try to post a video later showing the issue
Thank you

RE: Brushless motor not running - just beeping
Maybe an ad on for E-flite esc's, and getting them to arm, at least in my situation.
I had purchased the E-flite airliner, equipped it with the Eflite motors and 30 amp Pro esc's.
The only way I could get the esc's to arm was to have the throttle on the tx (Multiplex EVO) set to WOT when I plugged in the packs. I'd then get a single tone, and immediately had to move the throttle to off. Then I would get the rest of the arming tones, and the motors would spin up just like they should.
If I tried any other sequence I'd get nothing. Using a Hitec 6 rx, I tried every type of adjustment on the tx to change the arming. End points did nothing, reversing only had the tx stick working backwards. Would arm starting out at off, then going to WOT, but the off position was then at the top of the tx and WOT was at the bottom.
Since I didn't fly it often, and forgetting sometimes the sequence to arm it, I finally wrote the sequence on the back of a business card and taped it to the battery tray.
Not the best way to correct it, but this year the liner got an overhaul. New fans,motors,esc's. And the card with the arming instructions got taped to the two esc's and tossed into the spares box.
