I have an application where I need to remotely operate an accessory on a drone (on / off control) from distances of up to a mile (minimum). I am looking at the Thomas Scherrer TX700 Pro and Spektrum MD2 transmitter & AR610 receiver. Do I need to also purchase the Thomas Scherrer RX700 module or will the TX700 work with the AR610 receiver? I plan to use an E-Flight brushed ESC module for actually switching the load.
Alternate suggestions on how to achieve the needed range (1 mile minimum) and remote load switching (2 loads; 9 Volts DC; 350 mA max) would be greatly appreciated. The drone selection is being done by someone else (commercial application).
