GRC71 Theremay be some interferences (including magnetic fields), or bad connectors. How do you power it? Using the power supply, or batteries. If you are using the second option, be sure the batteries are fully charged otherwise the relay lock itself, once the voltage it's too low.

GRC71 You can fly the quadcopter for longer, changing the battery as soon as it runs out.

GRC71 According to the specs, it won't work with 5V, as the minimum voltage you have to provide for the double strobes version, it's 7.4V (2S). 3S 11.1V 4S 14.8V 5S 18.5V 6S 22.2V

GRC71 You can use 12V ONLY with the version that uses 2 strobe lights.

GRC71 To power the Arduino Nano you can to plug it to the USB of your PC-Laptop (5V) using the serial cable. You still have though, the option of powering it using the 5V pin, using a voltage regulator (voltage has to be accurate). If you use the Vin port, you can use up to 12V to power it, but this is the last efficient way, as you dissipate through heat the excess of voltage. Regarding the output you have also the 3.3V pin. I hope it's helpful.

GRC71 Yep!Please watch my YouTube video, about the launch of my Rocket Drone, filmed using the Hawkeye Firefly. The quality is not great, but the camera does the job. RC Lover san
