lol, yeah, I use it as the kill switch on the LawntoyLOL...I have that radio an fixing to use it today ,I forgot that it had that third button!......
I had a pile of AM radios at one point. I had it in my head like 10 years ago I was going to build an FPV, underwater crawler with running lights. At that time some people were saying that the AM radios penetrated the water better than anything else. I never did test that theory as I never went any further than picking up some AM radios/RXs here and thereI still use mine blue 27ghz am radio and receiver. And a few others I have. They have never let me down and it's from the 90s. The only thing is that it takes 8AA instead of the new 4AA. But still a good controller
