EKF Velocity Spikes


I have some difficulty with this drone and would really appreciate if some could take a look at the logs. The drone itself is a flat octocopter, take of weight 10kg with an orange cube, never had problems before with them. But this model does have spikes in EKF Velocity, which I did not have before. It does not go above 1, but also does not stay around 0,2-0,3 like the models before.

You can find the logs here:

I appreciate any help.
