Problem with 3.16? Instructions here.

These are from Dronefly.com. Great guys BTW. Some people could not get the Dropbox file so here it is.
Once completed, go back to the software and then turn on IOC.
You can't turn on until the compass is calibrated.
Good luck all.

I downgraded back to 3.12, much more stable flights now - less wobbling
