If you fly Core you can connect this to the Rx and get real time figures too.
For years the Sensor switch has trounced every other switch set up with efficiency and safety, I have more than 2000 flights with Sensor switches and every one has been faultless. My first one is still in the original Classic Flash ‘manual’ airframe, still the same Thunderpower 2s 2100 Prolite cells, I lost track on flights past 600 on that airframe, one of my friends went past 850 on his unit (his turbine expired at 127 hours!) in the Flash I average 110Mah use per pack per flight.
