You can actually use the map features to zoom in on your

I think if you try it and it works, then it works.
If not then configure it using the mast.
Much cleaner install without the mast.
Another question regarding the GPS module:
Has anybody done a write up of the procedure to add GPS?

I bought the Go Pro gimbal from Aeroxcraft. I haven't tested the gimbal yet, but Aeroxcraft recommended the Futaba S3154 servos.
Those are what I'll be using.
