Yes I understand an out of control drone is dangerous. I've had my share of nicks and cuts.
OK so the reason I thought 433Mhz was not good enough is because the rf modules sold for arduino only go for about 10cm but that would obviously be because of the power and not the frequency. So I would need higher powered remotes.
I know BT is rf but the BLE modules I've used (hm10) only go for a out 80m.
So what rf module could I use for at least 150-300m?
