I ordered this " Revo GPS" a few weeks ago after seeing the link in a post by Theothercliff, sorry, don't have the link atm.
I recently setup a clone Revo from BangGood with an OP V9. Works fine, on the bench anyway.
So, I disconnected the V9, plugged the "Revo GPS" into the Revo clone and, in 3 minutes had a 7 sat lock in my garage. Same results with OP Revo. Obviously no flight tests yet but it looks like we may have an alternative to the hard to get OP V9.
Stay tuned.
Edit:
My experience with the V9 when it's fired up indoors has been that the UAV image in the GCS Flight Data screen drifts quite a bit in random directions. That is definitely not the case with the Neo8, its been plugged in some 18 minutes now and has not moved. At all.
Gotta get this in a frame.
Edit 2:
Duh, have to enable INS13 to see what's happening with GPS. Image drift is there, same as V9.
Also have a Black Mag, gotta figure that out. All sensors calibrated ok.
Stay tuned.
