Same with my mini OP GPS with Revo. 7 satellites locked, this video,
.
The heli is a 120 sized wltoys v977. The mini GPS is 5.4 grams including the wires.
This is my prototype for the MQTT protocol to replace the UAVTalk protocol. The heli
does not actually need to fly for the development. But the heli could lift off to the eye
level before adding the 5.4 grams GPS. Maybe I will try to fly it another day to see if
can still fly. So far , now, it is 15.5 grams over its stock weight. Original product weighed
about 60 grams at take off. Now it is 75.2 grams.
Mine powers up at 9600 sending NMEA sentences.
