Did you get ever get a 3d fix with the BN-220? Did you give it a flight test? I bought two of these. They occasionally find a few satellites, but I've only gotten a 3D fix briefly once. My Hoybro Micro M8N GPS locks on in a few seconds, while the BN-220s can sit four hours without a fix.

Well, interesting... I just tried a taller antenna (VAS Ion V2) for my 5.8 ghz video transmitter, and my BN-220 got a fix within about 30 seconds! Subsequent starts are within 2-3 seconds. GPS failed with a 5.8 ghz lobe antenna attached to the VTX and with a Lumenier AAXII attached to the VTX.

Apparently I have to take it all apart again, because it doesn't work to run the GPS wires between the flight controller and Runcam Split Mini 2 circuit boards. Ack! I bet I've taken it apart 20 times now.

Is it normal for these to run hot? I'm also having problems with the GPS struggling to get a fix, but I have it very close to the VTX. Perhaps I need to work on a different layout.

Update: Moving the vtx antenna away from the GPS seems to have improved things a lot - thanks for the tip!
