"I'm having a similar issue. I setup my JDrones Arducopter in plus config with the APM2 board. Levelled it and started up in stabilize mode. I ran it through two batteries in stabilize mode. It was flying perfectly well, just ouling a bit to the…"

Arducopter 3DRB Quad Propeller Size Range

My Arducopter kit came with APC 10x4.7 propellers. I'm wondering if these are the only propellers I should use or if there is range of sizes and pitches that will work? Specifically, would it be okay…Continue

Hi there, my Arducopter/APM2 build has been coming along nicely and I think I am almost at the finish line. I am working on configuring my ESCs and am having a problem with one of my motors. I was…Continue

Hello,Just received my ArduCopter kit and APM2 a few days ago. I have been working on the assembly, and now that I have completed 2 arms I think there may be a problem with the way I am mounting the…Continue

Arunabha Bhattacharya replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"Yes, However they need to spin faster. A propeller is more efficient with a larger area to grab. If they are too slow with larger area then trying to coordinate the attitude of the propellers is bumpy with a 2 blade prop. A 3 blade prop with…"

My Arducopter kit came with APC 10x4.7 propellers. I'm wondering if these are the only propellers I should use or if there is range of sizes and pitches that will work? Specifically, would it be okay to use my arducopter with 9x6 propellers? See More
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"You were right, it was a calibration issue. I basically fixed it by calibrating my radio over and over again with different throttle trim until something worked. It finally worked with the trim all the way down but then I couldn't arm…"
Vernon Barry replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"No, not if you are using stock 3DR ESCs, that's what I fly. I will say this, follow my other post if you have a usbtiny or other AVR programmer and flash the ESCs with SimonK.
Point is, you have a basically "kit" setup of parts…"
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"I'm using the 3DR ESCs that came with my kit. I have been re calibrating My radio and now two of the ESCs seem to work. But I drained the lipo and my radio unbound somehow, so Im waiting on the charge now. youre saying i should look at the…"
Vernon Barry replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"Yes, what ESCs are you using (sorry if you said this before)?
It's highly possible your ESCs cannot accept the output rate of the APM. There is a setting to adjust this, but I think you must use Arduino to edit the firmware and then flash it.…"
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"I have been tinkering with it a bit more and it seems that every time I plug in the LiPo the ESCs make the musical tone followed by two beeps noise as if they are entering calibration mode. Is this possibly the problem?"
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"All 4 beep sometimes, but usually it is only 3. I reflashed the Quadro firmware as well as cleared my EEPROM and re did the first time setup config. Then I did manual calibration for each of the ESCs but to no avail.
When I do an auto…"
Vernon Barry replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"If all 4 beep then the APM is not booting or has the wrong code on it. Try reflashing the firmware via mission planner"
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"I went down to the PDB to look for problems, reconnected everything but didn't really see any problems. I have tried automatic calibration a few times and since I took it apart and it seems to work for all four motors and they all move in sync.…"
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"Hmmm, they definitely worked before the first time I had it going, that's why I didn't think it was wiring. You're right though I could have easily bumped something. I'll have to take it apart tomorrow and recheck my cables.…"
Vernon Barry replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"Beeping always indicates no signal from the APM. So logical guess is wiring issues on the ESC input side. Otherwise, the other option is the APM is not booting or the code it wrongs and just not outputing PWM."
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"Wow, thank you! That worked perfectly. The motor end of the cord had become disconnected. Thanks for your help! Now for some reason two of be ESCs won't stop beeping and arm. The one that had the broken motor is fine as is another one. The 2…"
Vernon Barry replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"Like I said, disconnect all three wires so you are only testing the motor with the multimeter. Set it to Ohms or diode test (normally they beep) short the two test leads to verify the meter shows very low ohms or beep, then test any two wires at the…"
Calum Barnes replied to Calum Barnes's discussion Arducopter 3DR-B 880kv motor setup - one motor will not spin"Thank you! That would make sense, is there good way to figure out which one it is? Thanks for your help, I will look at the connectors now."
