I recently purchased a UBLOX LEA6 GPS for my quad.
I have had some good flights and some not so good.
This evening I did the power hack on my APM 1 to power the receiver from the USB.
I have the APM 1 connected via USB and the copter is indoors so not many visible satellites.
What I have noticed since then is that when I switch the transmitter on I am losing GPS lock.
Also the altitude is jumping all over the place when the transmitter is on probably due to no GPS 3D fix.
Anybody else with a UBLOX GPS and FrSky transmitter having these problems?
