Since i an also an angler and go surf fishing i need to develop a bait release mechanism to be fitted on it to use the drone for sending my bait into the sea. Since i can not connect any thing to Phantom 4 control board i would need to make a payload switch which operate by a separate transmitter switch i just need to send a open a and close signal say a up to 500 meter to a switch which is some thing like this
