I use:
arduino nano v3
itg3205 gyro
parallel nk connection
v1.8 software and the config is
# define I2C_SPEED 100000L
# define ITG3200
# define NUNCHACK
# define ITG3200_LPF_256HZ
# define INTERLEAVING_DELAY 3000

can you tell me how to fix or if it is a gui bug?
sometimes it happens after 3 minutes or more and the graph of nk is flat but the image of quadcopter rotates...
any suggestions?

you could try from the basics first disconnect nunchuck and just have wm+ connected see what happens then..

works normally so is the NK
if I cut the NK in the middle? can solve the problem?

Personally, I would just get another brand of Accelerometer.

I found this on ebay can you tell me if it creates problems in parallel connection or if it's good?

I have been intending to purchase one of these for testing however, I have purchased some MMA7455s from the same vendor and they work great. The ADXL345 appears to have the same design and can use either 3.3 or 5 volts. It should be a plug and play solution but I can not say for sure.

I do not see MMA7455 in the config file ... is compatible with the multiwiicopter?

No the MMA7455 is not part of the MWC, I made those modifications myself. It would be best to go with the ADXL345 because that code is maintained.

What type of Nunchuk? There are gazillion of different nunchuk boards.
How do you power it? Some can take 5V fine, some need no more than 3.3V.
I'm afraid that сutting it in the middle will just create more problems since usually there are traces that go around the whole board, like ground and power.
But for sure it won't solve that problem with Nunchuk data that you have.

After I cut the nk creates the same problem ... I tried 5 and 3.3v
I finally bought an ADXL345 from 20 25 day arrives and can try
