Maybe some of you are already using this mix. To my knowledge, none of the electric pilots I fly with are using it except for the one who recently showed me the mix.
The idea is to pick a switch on your radio. When the switch is in the ON position, moving your throttle forward will run your motor. When the switch is in the OFF position, you can move your throttle stick, but the motor will NOT run at all. This is like a kill switch for electric motors. I find this to be a major benefit for safety, since we know what happens if you accidentally hit that throttle stick when the motor is armed. When I connect my lipo batteries to the ESC, I get close to those big props. Now, I put the switch to off, and I can connect my lipos with a piece of mind.
So here is how I programed my Spektrum Dx8 radio (I'm sure other radios will work similarly). On my radio, I use the switch labeled "RUDD D/R" as my kill switch for the motor:
go to Mixing on front screen
go to Mix 1
then mix Thro - Thro
set Rate -100%
SW RUDD D/R
This should give you the RUDD D/R switch control of your throttle stick. In the forward position the throttle is on, and in the rearward position the throttle is inactive.
By switching the minus and plus signs under "set rate", you will make the forward position inactive, and rearward on.
I will use this mix now on all my electric planes because of the safety aspect.
