Is wonderinig around on map when copter sitting on ground normal?

It is a 3DR Y6B, so it is on a mast. This is (was) the exact same copter with over 100 successful flights and missions, after going through the learning curve of course.

It is simply a mystery why it is wondering on the map just sitting in the yard. It may have done that before but it seems like I would have noticed. Dozens of takeoffs were done just 20 ft. from that spot.

The copter will need one arm, a motor plate and possibly two motors (one is totaled). After looking at 3DR options, since motor plates are not sold separately (yet the arms are), I'm not sure what I want to do now. Maybe for $50 the Quad frame isn't looking bad except I don't know a X4 would handle the weight of a 6k mah battery.

If they offered the PDB I'd even consider going for the X8.

I was able to dig up enough parts to put it back to together today and run some tests before attempting to fly again.......maybe tomorrow I'll have enough nerve.

compassmot was 4% today, I don't have the other data at the moment, but it is all well within spec. I left the props in (for compassmot test) so it couldn't take off, armed and ran in stab mode. Obviously the alt was 0, so I flipped into RTL. I would think arming, starting in stab mode and going to RTL, if the alt is 0, wouldn't it just shut down and disarm? Instead, it went to 52A current draw as if it were trying to take off.

Can someone confirm RTL behavior if alt is 0 and has not moved lon/lat? What should it do? Disarm or take off? I turned off tx and FS worked; copter disarmed.

Even with hdop at <2 and 10-11 sats, the copter was still wondering around on the map. 3DR is baffled at this point as much as I am.

Anyway, I was looking at the T-Motor 2216-12 800kv motors for a Quad X4 build. E-Calc seemed to like it. What specific model motor did you get? How did you decide on 630kv?
