I'm pretty new to UAVs and DIY drones, and I've been tasked with building a Y6 as an environmental research platform (seemingly a common thing...). I've got pretty far with my build and just waiting on propellers so I can complete transferring to the Y6B configuration, but I've found a problem with my throttle fail-safe that I'd like to resolve before starting test flights.
I think that minimum throttle PWM should be greater than the Tx off PWM, so the failsafe can be set to trigger at an in-between threshold; however, at the moment both minimum throttle and Tx off result in a PWM of 990 (received by the APM).
Can anyone offer any guidance on resolving this? (I'm using a Taranis X9D transmitter, FrSky X8R receiver, and APM 2.6. I think I might need to increase the PWM output from the Tx when the throttle's in the minimum position, maybe by reprogramming that channel's minimum from -100% to -90% or -85% and re-calibrating the radios, but I'd really appreciate someone letting me know if this is a daft idea!)
Thanks for any input,
