Hi my quad isnt arming, I can spin the motors from the motor tab and i get input on the receiver tab when im moving the sticks but it doesnt spin the motors.
I checked and calibrated everything, i have a low cpu load… no beep codes at all at least not anymore — see above ;- , no blinking, nothing. What arming disable flags are you getting? Can you try flash an older version of BF see if that works? If this works, but not Betaflight 4. Hi, thanks for this great tutorial. Betaflight shows the switch transitioning and the yellow indicator moving into the yellow band.
However my quad does not arm. My throttle is in the minimum position already and i have also tried trimming fully back which makes no difference.
Can you please let me know what the possible problem could be? Ideally it should be lower than , e. Is the only way to know for sure if the flight board is toast is trial and error?
Just throwing this out in case it might be useful to someone else. When I had the issue of the gimbals not responding in Betaflight, it was the Failsafe mode which I accidentally enabled on my transmitter.
Flipping the switch to disable Failsafe had everything working normally again. I plugged in my receiver which is for an Radiolink AT9, but as soon as i turn on my remote, the quad beeps constantly of short beeps. Receiver is probably not setup correctly. I have no experience with Radiolink, please join up our forum and see if you can get help from our other members? I have a flysky turnigy evolution. Thanks for your detailed tips,it should had helped me and people just involved in,but I tried everything even googled lots of vids but still unable to make arm activated in Beta Flight configurator, however flip fail safe and fly mode switch work fine and beep, if I check all the tips,what else would I missed?
Today December 9th is my first time flying crossfire module with the nano rx. I think? Can someone help me out with this one?? Check your BF settings. Please help me. Could be a wrecked Flight Controller board and I have ordered a new one today. But more worried my Taranis xd9 broke somehow :. No change. Open brand new R-XSR receiver, bound it and plugged into the freshly soldered wires, successful binding but: — No change 3.
My next step is to de-solder all wires then re-solder wires to new FC when it arrives in a day or 2.

Ok At value of 30 it is working fine there are no twitching detected in the motors.
If this is by design as per tuning notes this is not a bug however it feels that motors are idling at higher rpm that I was use to and feel that you should be able to reduce the dynamic idle below 30 without any issues it worked in the previous nightly builds.
I will leave this open just a little longer for someone to acknowledge it and then I will close it as this might not be a bug at all. I don't use dynamic idle, but I noticed in 4. Not really a stutter, more of an oscillation. Did not do the idle surge in 4.
