dji a2 two purple flashes

[lugaluga]

Hello I just updated the last version of my djia2, but now I can't get it to fly, it blinks purple two times... Everything works except the engines

Hmmm, two purple flashes normally means that you are in GPS mode and that your sticks are not centred. If you can get a vid of what you are seeing, that would help. Have you done the combo stick move to initiate the motors?

As Carapau said, two purple flashes means it is receiving a command from the transmitter, ie sticks not centered. Normal behaviour. As above have you tried a CSC? Did the motors run before the update?

Thank you it worked perfectly but the sticks were misconfigured. But now I have another problem when it starts flying it does like a feather effect and it falls. Yesterday it flew perfectly and today it started to do this. Will be bad the dji a2v

This looks like your gains are perhaps too low. Can you post your gains please.

If you've just set it up why would you instantly blame the A2?

As Carapau said, your gains do look too low. It seems slow to respond to attitude adjustments which means it over corrects and bounces back in an endless cycle.

 

[lugaluga]

the gains are fine, tomorrow I´ll post a picture. The weird thing is that yesterday I flew it for 15 minutes perfectly, but out of nothing it starts the feather effect.

 

[Carapau]

Well, can you post your gains so that we can have a look- it still sounds like a gain issue of some sorts.

 

[Glennyboy]

looks like low gains to me....or maybe incorrect imu mounting co-ordinates! show the gains and imu settings!

100% seems very low to me. I'm not an A2 man so couldn't comment accurately.

 

[Glennyboy]

yes tooo low.

try...

basic
180%
180%
150%

atti
120%
120%
110%

and then plus minus 10% see how it goes!

I am having the same problem with the 2 purple flashes. How can I fix it

 

[Carapau]

Look at the 2nd post in this thread and read the manual- 2 purple flashes shows the A2 is in GPS mode and that your TX sticks are not centred.

Not centered or not at zero? I have my throttle spring loaded.

 

[Benjamin Kenobi]

It also means cyclic control.

Have you done the transmitter calibration? (sorry, I have to ask just in case, although I'm sure you have :nevreness.

You also get extra flashes if within 10m of the home point. Are you getting the flashes on the landing zone or near it and have you tried flying 10m away?

 

[Hovercheck]

I only get the Double flash when I try to start the motors. I have calibrated many times. If I leave the sticks alone I only get a single flash.. My sticks are spring loaded to the center.

 

[Benjamin Kenobi]

That's normal behaviour then. All good. :nevreness:

 

[Hovercheck]

But the motors DON'T start.
