SpeedyBee F405 Wing Mini Question

[Highflyer98]

Hello,

I am getting back into the hobby, and I am trying to build a wing. I bought the SpeedyBee F405 Wing Mini and got it all setup with INAV. I got the reciever to work and I am able to control the servos. I can not for the life of me get the ESC to calibrate though, everytime I follow the steps I the esc just starts beeping every 2 seconds.

I broke out the multimeter and tested the esc terminals and was alarmed to find that there was only .3 ohms of resistance between the positive and negative terminals. I did not see any solder bridging the gap, and even after removing all of the solder I still had .3ohms of resistance.

I ordered a second of the same flight controllers from the same Amazon seller, and I just took the new one straight out of the box and tested it with my multimeter and found it also had .3 ohms of resistance between positive and negative esc terminals. Is this normal or did I get 2 out of a bad batch?

Thank you for your help!

What ESCs are you using? What protocol did you select in INAV for the ESC? What port did you plug the ESC in to on the FC? Are you using the SpeedyBee app, or the traditional INAV configurator?

I have the same FC at home, but am away for the weekend and can't measure the resistance. I would not be too alarmed because you are measuring all the other electronics, and you didn't let the magic smoke out when you plugged it in.

Cheers!

Thanks for your reply LitterBug.


It's the ZOHD 30 amp ESC that comes with the PNP Dart 250G. I have tried every ESC protocol in INAV and I tried using both of the motor ports separately or just enabling both at the same time. And I only tried the INAV configurator, I will try giving the app a go and see if anything changes.

I soldered the ESC tabs directly into where the battery leads connect, set channel 5 on my transmitter to be the throttle, enabled an extra servo for channel 5 in INAV, and plugged the ESC signal and ground into the servo port on the speedy bee, and I was able to get the motor to spin so I know that the ESC is working.

I would just leave it like this but channel 5 functions as an OFF of ON value and I can't figure out how to make it a continuous value

Ah.... I have a Dart with a different FC running INAV and have been having "fun" getting it to calibrate too. It goes in to programming mode and not the usual calibration mode. I need to get the Dart instructions out for the esc. It's an ESC thing, not an INAV thing.

If you are using ELRS, Channel 5 can only be on and off. Use it for Arming the FC. It puts the ELRS link into active mode at the same time. You have 8 full range channels PLUS the arming channel. (1-4) 5 arm (6-9)

Here's my build:

LitterBug's dRonin / iNav / Aura5 / ArduPilot / *Flight FC enabled Wingy Thingys

Matek has given us a patch with reworked UART code to test. So far, testing looks promising. The telemetry calculation is still a mess though.

It may have been a timing thing.

I was able to successfully calibrate the ZOHD ESC tonight using the INAV control panel. Raised throttle to full, After Plugging the power in, The ESC beeped twice, I dropped the throttle to 0 and it beeped twice again. After it sat a few seconds, it beeped a few more times. I reset power on the ESC, and the usable range was correct. Before it had a big space at the bottom of the throttle that was wasted.
