Everybody knows how dangerous a spinning prop can be. You learn to respect them or suffer the consequences. It is prudent to take precautions. It is smart to:
- When at the field, powering your model is the last step before a flight, and unplugging the battery is the first thing to do after landing.
- Stay clear of a moving propeller. When hand launching, keep fingers and other body parts away from the propeller.
- Remove the propeller from the motor before working on your model.
- Configure a throttle arming switch on your transmitter and check that your motor is disarmed before turning on your transmitter.
This quick tip, I will show how to configure a switch on your Taranis to disable your motor and propeller. To arm the motor will not only require a switch to be activated, but will also require the throttle to be at its minimum (throttle stick all the way down). I use switch SA which is the switch right above the throttle/rudder stick. I chose this switch because to arm the throttle, you must take your had off the throttle stick.
- Logical Functions – Configure two functions as follows. The first [L19] will detect when the throttle stick is at its minimum (full down). The second [L20] will detect when the throttle arming switch [SA] is activated and check that the first function [L19] is true and the throttle stick is at its minimum. If it is not, the throttle will not arm until it is.
- Special Functions – If you want the throttle arm state to be announced, create two Special Functions to play when the state of the [L20] changes.
- Curves – Create a two point Curve to be used when the throttle is disabled.
- Inputs – Create a second throttle state in the inputs tab. The top state will disable the throttle by using the Curve just created above and be active when Logical Switch [L20] is false (or !L20 is true). The second throttle state will be the default and used when the throttle is not disarmed.
