Hi all, im New here and to this great hobby I have built my first quad and having a blast launching it for the first time last weekend. I do have a problem that hopefully someone can help me with. I am wanting to Sent up my radio to warn me when the Voltage is getting low on the quad battery but do you think i can find how to Set this up on the Nirvana radio. Any help with this world be great appriciated. Im sure it is simple but Just dont know where to go in the radio to do it. Oh and it is running the underground fpv software. Thanks again
