First fpv drone. My mobula 7hd is supposedly frsky mx+ and trying to bind to betafpv lite se radio. I have the radio set to frsky d16 out of the box but I have cycled threw all other protocol and nothing binds. Pressing (what I think is the bind button) and the lights do not change blinking or not. Reciever is Speki+ dsm2 dsmx. Is it even possible to bind. Nothing that I have found shows info on the speki. Thanks in advance.
