“painless”, “but a bit of a learning curve” ??
It took me 2 days to using Express LRS configurator to get my RP1 bound to the TX12. Had to degrade my Python version. A chaotic, confusing, complicated setup. When you do this stuff for the first time, try different RC’s, maybe one will work. My RP1 came with no docs.
I might have to set a bit somewhere to get it to work! (Complete Parameter List — Copter documentation)… First time I read that was in this forum.
