Yes, Please send a log file.
How much is a bit? In the 10 seconds of loiter time the copter floats just under your GPS accuracy.
For better results you may want to think about a range finder or RTK.
You are also flying very low and not above ground effects.
How high do I need to be?
How can I find how much is a bit? Will it be in this log file: https://drive.google.com/open?id=1vitY_CuWGpb1bsJBohvVtiP4yKel-EF_
Sorry, I’m very new to this
Sorry I should have Ask, How much does it drift?
This log is high enough. I see some movement but less than GPS accuracy.
How much is it drifting?
yes i just want to confirm that every thing seems ok in your log.
could you send a video of copter flying?
Hey, sorry for the late response. It’s kind of weird in the way that it doesn’t drift and then suddenly it will move like a couple feet and then come back to it’s original spot. Could this be fixed or is it just a limitation of the GPS?
When it moves, the odd thing is that it isn’t because of the wind either.
Unfortunately, I just moved into college and don’t have my copter with me. I’ll be back on the weekend when I’ll be able to fly and I’ll send a video then! Thanks!
Sounds like the drift is about the same as GPS accuracy. There are better GPS, of course at a cost.
A second RTK GPS or range finder helps. Nothing is perfect even at 1CM reported accuracy its not going to hover exact.
Any suggestions for a reasonably priced RTK GPS or range finder? Thanks!
This is what I use today. This receiver cost with case is $250 each and perform excellent (not perfect).
The antennas on this link are fine for a base station but not for rovers, they are too heavy!
The ANN-MB antenna is recommended.
I am waiting on the HerePro with full FC capabilities. I here December is a fair estimate for release of beta units.
There are some other F9P with integrated compass and antennas but I do not have a link.
If these are out of your price range look through the ublox site for M8P Receivers.
Thanks! Unfortunately this is really out of my price range haha. I was thinking I may be able to find something under $50, but I guess it isn’t worth it. Thanks though!
Even with a M8N if you mount it up and away from your electronics you should get very precise loiter and althold. My 180mm mini quad with a micro M8N mounted right above the camera still only drifts a foot or so.

Does it look like my GPS is high enough? Or should I bring it higher? Thanks!
Yes your GPS looks high enough and the GPS you have is ok too. I have the same one working just fine. I see sub meter drift as normal & fine for the majority of applications.
Ah ok, in that case, I guess I’ll stick with this and deal with the slight drift. Thanks! Do you have any experience with the Dshot protocol and whether or not it will help? Thanks!
From what I have read the would be no big benefit to this size of quad. I am just learning & have no expertise with these BLHELI / dshot questions.
Ah ok, I’ll try to do more research and see what I see. thanks!
