I feel ya I'm sending mine back in tomorrow it has taken 3 really hard hits and I don't trust this thing at all , I hope they will replace this instead of repairing it . We did recalibrate the compass which helped but after a few flight it took off again . The guy that has been helping me really understands these things and he took mine out and flew it really hard and it settled down , keep I mind even when it is in gps mode it will drift around a little bit but should stay within about a 4 inch circle . Also try to recalibrate the compass out I the middle of the yard far far away from metal or magnets , I will take my iPad to the field tommorow and show him your post to see if he has any ideas , and if you want I will tell you what they found at dji if you want ,keep in mind I'm no expert just having fun and learning,so we all have our own opinions and ideas I'm just tryin to help a brother out if I can have a great night George
