3RD quad + Pixhawk PX4

Hi everyone,
I built a 3RD 2014 quad, linked it to a FrSky Taranis, calibrated ESC’s & all controls, and set 6 flight modes (on Ch5) & RTL (on CH7) etc. using Flight Planner.
Thereafter, whenever I powered up the quad, the pixhawk went through its normal LED sequence fairly quickly and as a consequence have flown the beast successfully a number of times - responding to the Taranis controls as expected.

Now when I try to arm it I get the usual “bleeps”, but now it takes sometime before the pixhawk flashes green to indicate that that GPS lock has been acquired and that it is ready to arm. Once armed then all seems to be OK.

I have re-inserted the Pixhawk SD card a couple of times should that have been the cause of the problem.

Can anyone give me any clues as to what may be causing the long delay please ?

The micro SD card in the pixhawk is solely for flight logs and would have nothing to do with the delay you mention. GPS signal doesn’t always lock at the same rate. How long does it usually take?
