Work has been kicking me hard lately but I had a bit of time to get the Tx programming for my airspeed warning.
Most tutorials on the web are so focused on battery warnings that it seems that other telemetry modules are overlooked entirely. I'm using logic switches in my Taranis and I am currently running OpenTx 2.1. I know 2.2 is the current version but I've just not had the time or interest to update yet... and the radio still works to my liking. Just two logic switches are needed here. To explain a bit on what we are dealing with here, a= the input and x= the variable. 2.0 is the delay so the airspeed will need to be < 30MPH for at least 2 seconds before the switch is on. This prevents the switch from activating if there is variability in my airspeed at the edge or in windy conditions on approach, or at least softens the hard cut for this switch to be on. So in L1, the airspeed sensor input is < 30MPH and also only active when L2 is active. L2 is active when my throttle cut switch (SF switch) is active. So L1 then is only on when the throttle cut is off AND when my airspeed is less than 30MPH.
To get the audio to activate we are setting up a special function just like you would to drop a bomb or indicate that the gear is up or down. The input for this is L1 since it will only be active when L2 is active and the airspeed variable is met. So, when L1 is active, it will simply play the value of my current airspeed reading. The nice thing about this setup is that I get a SINGLE warning and I correct it or not. If I go above 30MPH the switch resets and when I land is will go off again. This alleviates a lot of the nuisance repetition of telemetry readouts I see so much of. YOU fly the aircraft, not the telemetry. I view it like this, if I am in the cockpit and I'm landing I look at the airspeed indicator. It then tells me how fast or slow I need to go ONCE until I check it again. Since I cannot stare at my Tx when I'm flying LOS I need the audio readout for the check. Its a balance of safety and informed flying.
With this all set the only thing I need to do is set some aileron differential. I foolishly disassembled the aircraft last night to clean shop, forgetting I need to do this. It should be fairly straightforward, I just need the ailerons to be plugged in to ensure that the differential is applied correctly. Meaning, I want more UP deflection than DOWN. Since down deflection induces drag, it creates a yaw effect and the differential will reduce this. This is why I went with two independent channels for ailerons. Again, I'll start with 10% and see how she goes. More or less can be easily changed at the field.
