INAV 2.0 Matek F411 FC Disarming in Flight! Mini AR Wing

Using INAV 2.0 on a Matek F411 FC. Default settings for the 600mm wing presets. I also followed the steps to enter the commands in the cli from the inav wiki fixed wing page. So after launch around 4 minutes into flight i was feeling everything was going well... Then all or a sudden i see the stat screen and have 0 control over the plane. So i flipped the disarm switch, lowered the throttle and flipped the switch to arm and i regain control. So i was puzzled thinking my radio signal had dropped out and some how failsafe didn't kick in.. Which i had confirmed that failsafe did work when i tested it on the bench. So i kept flying just to see if it would happen again. 6 minutes later the stat screen popped back up again. So i repeated the step as mentioned before to regain control and i could not get any response out of the FC causing my wing to crash. So i took it home thinking the rx for radio control went bad and installed a new one. And i went over all the setting in inav. Everything looked ok. Next day, same thing happened again but i regain controlled and landed. Bug possibly or glitch?? Video link below of osd footage of flight.

@JDFPV The video says that you disarmed by SWITCH.

[teckel12]

@JDFPV I would set disarm_kill_switch = OFF so the kill switch is disabled unless the throttle is also low. With this set to ON, the kill switch works no matter what the throttle position.

[digitalentity]

@JDFPV what radio system are you using? Some radio systems (most notable FrSky R9) are known to send random channel values on some occasions.

INAV 2.0 uses a lot of fixes to make RC link more reliable, but you should not rely on firmware to fix otherwise broken hardware.. You can try setting sbus_sync_interval = 1500, it will make INAV work correctly with receivers violating SBUS standard. Disabling disarm_kill_switch is also a good idea to make sure you don't accidentally disarm while throttle is above zero.

From video this looks like genuine switch disarm - my guess is that it's a flaky radio hardware.

[JDFPV]

i'm using dragonlink v2 on a devo 10 radio. Been using it for years with 0 problem. And actually i flew my other plane after this and it has the say profile settings same disarm switch and it works fine. But i will try the set disarm_kill_switch = OFF.

[digitalentity]

It may be a problem with particular receiver. I assume each of your planes have it's own receiver.

[JDFPV]

Each plane uses a micro Dragonlink. 3 planes have inav 2 has fy41ap lite flight controllers.

[JDFPV]

All other planes work fine with inav. Using 1.8 on the Nano Goblin. Using 1.9.1 on my fx79.

[digitalentity]

The only thing we can conclude from your video - FC was disarmed by a switch. Without BB log it's hard to troubleshoot any further. Since MATEK411 doesn't have the onboard flash, using old good OpenLog is the only option here.

[JDFPV]

And I actually changed the rx on the 2nd flight.

[JDFPV]

what is OpenLog ?

[giacomo892]

@JDFPV https://www.sparkfun.com/products/13712 Serial logging device.

[JDFPV]

I totally dont have space for it in the plane I'm having trouble with. I will test fly it with the changes made this weekend and I will report back to you guys. Thanks

[JDFPV]

Problem solved. The internal 5v 3a bec on the brand new matek f411 board went bad. Causing the rx to go nuts with over voltage. Thanks INAV!
