Joystick takeoffs stopped working

[wildwest450]

It worked fine out of the box, starting working about 50% of the time, now it will only launch from the controller screen. I only have 3 1/2 hours on it and it has worked flawlessly besides this. I do know the stick sequence as it worked out of the box. I will admit i'm a newb so maybe I accidentally hit a setting? I am running a custom controller setting and not mode 1-3. That's all the info I know to give

I would recommend to re-flash the SC firmware using DJI assistant for M2, and then start again with all the settings. It will also help you to know the settings better.

Welcome to the forum

I agree with @Latawiec about getting everything back to default and going from there.

 

[wildwest450]

I re-flashed through DJI assistant2 and it said update sucessful on the controller. Went to test and when the drone connected the controller popped up a message asking if I wanted to update? I said yes and it showed 44% on the home screen, the it went up to 100% and said update complete. I hit the go fly button and the first checklist screen popped up and there was a red exclamation point in the firmware section, it said incompatible firmware. Should I do a factory reset? The sticks still didn't work but it was going to let me take off from the screen. I don't feel comfortable flying with that warning.

Re-flash again via assistant 2 and ignore the over WiFi update. Check if, the manual takeoff will work.

 

[wildwest450]

Will do, thank you

I would check and make sure the Controller, Bird, and Batteries all have the same firmware.

Not starting is one of the symptoms of this thread...
At my wit's end... what am I missing (problem with M2P)

I'm assuming if you do all the updates, they are?

Updated again, turned wifi off. Update successful, no firmware warnings on MP2 start, no go on the sticks, takes right off through the smart controller. On a positive note, after landing, as soon as the props shut off a hummingbird literally flew in and licked one of the props then flew 3 feet away and landed on my neighbors fence. That's a first for me

You can check and make sure in the Go4 app. The batteries all have independent firmwares and have to be updated individually. You can fully update, change batteries and now have firmware issues.

Are you using "mode 2" on the sticks?

Are you using "mode 2" on the sticks?

I started in that, but it wasn't working for me. I went to a full custom setup today. It was doing the same thing before I switched.

 

[wildwest450]

If I have to launch through the app, I'm good with that. If the glitch compromises my MP2's safety in the future, i'm not.

 

[wildwest450]

Update: I put the controller back in mode 2 and it throttled right up with the sticks. I'm going to assume that the re-flash cured the intermittent problem I was having in mode 2, but once I started using the custom stick layout(yesterday) it must disable the stick takeoff. Everything else seems to be operating correctly, thank you for your help

 

[brettbrandon]

It may just be a matter of figuring out the new stick positions with your custom setup to trigger the old positions for startup if that makes sense... Example, both sticks bottom right ect. Just a thought.

I might be talking out of my a**, but you know what this makes me think?

The manual start is not looking at the position of the sticks. It is looking at the commands being sent.

My Mavic Air starts with the down+out movement (I've seen people do down+in, but it doesn't work for me).

In standard config, that means the controller is sending down + yaw left + back + strafe right.

Perhaps it is the command combination, not the physical position of the sticks that triggers the manual start. That might explain why a custom setup doesn't work.

Then again, I don't know from Adam, so...

 

[wildwest450]

I'll give it a shot

 

[paulatkin73]

usual reason for drone not to arm with sticks moved inwards is the movement of sticks pots in the controller housing that prevents em from producing the values correlating with a stick`s position in the corner. as i explained in the other thread - you need to re-calibrate the controller and during recalibration keep a little bit of space when you move sticks to that corner location, so it would not be affected during actual live operations. you should be able to see this in the post calibration screen well, if it produces corner result properly or not.
cheap potentiometers suffer from this issue - i get it in the frsky xlite - but never in the $900 futaba. but, there are always workarounds.

 

[brettbrandon]

I thought I read somewhere that the Mavics use magnetics with sensors for the stick input.
I could very well be wrong about that but if it is then there would be no pots.
