Nano GPS FPV-Racer Mod
FPV racing quads are getting smaller each day. The smallest ones with brushless motors are only 120mm wide. Upgrading these micro drones to have GPS return-to-home, will require a mini flight controller and a mini GPS with magnetometer.
The mini APM GPS (N95) is a very small GPS module with compass!
It costs under 14usd at banggood and performs great out of the box.
To prevent the compass from getting interference from the ESCs, I designed this micro GPS rig for mounting the unit on the smallest brushless quadcopter frame.
Watch video for the wiring of the mini APM + GPS, and see the smallest GPS FPV-racer in action! : )
