Due to the poor GPS performance of the Iris and issues on some of them where the GPS presses down on the Pixhawk causing a wide array of other issues, i just ordered a mast kit for the Ublox GPS.
It will take custom cuts int the top cover so it will have a slot for removal but I'll figure it out when I get all the parts.
My GPS has been sent back for replacement and I have asked 3DR not to remove the protective cover from the new GPS. If they don't follow those instructions I won't be able to use the mast kit.
Anyone else tried this?
