VIFLY GPS-Mate with Built in Battery

Must have with GPS

Lock satellites before you plug in. I normally lock 20+ sats before even plugging in the battery.

I use this for all my long range builts

I use this for my 4" and 7" LR builds. I have never had to use it. But I have tested it and it works as expected.

An absolute must for anybody flying with a GPS. Will make you lock onto more satellites and at record time. Please put these in your long-range birds now!
