I'm having an issue using active track. In the attached video sample, I'm using active track while cycling along a rail trail at probably 6-8 mph. I have a MP2Zoom with a Smart Controller and I'm using trace mode. I'm not touching the controls on the smart controller while riding. As you can see, the speed of the drone is yo-yo ing badly. It speeds up and then hovers over me and then speeds up and hovers again and again. This footage is unusable. Is there a setting to have the drone follow at a constant speed? Many thanks!

Maybe it's more of a yo-yo ing?

I made the video public on my channel. Thanks for watching. I really only wanted this to be visible to people who clicked on the link and made it private but no one could watch it. This is so frustrating.

Yes, I can view it now. Try calibrating the OA system in Assistant 2

Can see the video now, this is not the normal way the M2 in active track behaves.
Active track works with the camera and the sensors! Did you have a good calibration of the sensors with the Dji Assistant?

This is far from what I have seen here indeed.

Hm... strange... I have M2Zoom, but active track works good and smooth for me.
But i usually use it for more slowly objects (like walking people).

I haven't calibrated the sensors. I'll try that. A week ago, I purchased a new MacBook Pro that only accepts USB-C cables and the charging cable for the Mavic is USB 3.0. I've ordered a dongle that should arrive tomorrow and then I'll be able to connect to the DJI Assistant again. I'll let you know, thanks!!

I've noticed that using RTH the drone will attempt to land as much as 8 feet from the take off point. Would calibrating the sensors help with that as well? Thanks!

I've used Active Track to follow my nephew riding his dirt bike. He's not going full speed, but definitely riding quite quickly. My Zoom kept up quite nicely and had no stuttering. I was really impressed with it!

After saying how my Zoom could track a motorbike I have now encountered this problem. "Yo-Yo-ing" is exactly how I'd describe it!

Yesterday I was walking in a forest and my Zoom started doing exactly what OP's video shows. I cancelled Active Track, went back to Normal Mode and then re-did Active Track and the problem went away. Still, it's a bit of a worry. I'm not sure why it happened, or why restarting Active Track fixed it but I'd never encountered it before.
