Low battery power alert!!!
Hi guys, I am reasonably new to model flying and fly all electrics at moment. I was just wondering fi anyone knew of a gadget that mesures your battery power whilst the plane is in flight and transmits an alert of some kind when the battery/s are approaching thier the stage of being to flat to keep the motor flying the plane? Maybe some kind of beeping at the tx or a device that is with the pilot??
Let me know if something like this or similar is available on the market.
Cheers, Milan.
