Thanks Jim,
I agree that losing a small amount of data 100Hz may not matter for sport flying, but since the non-standard SBUS prevents the X10 from setting the failsafe positions I can't use it. That's why the news about the X10+v3 supporting CRSF is encouraging.
I am learning about ELRS radios and receivers now and found a significant problem with the currently available receiver that have PWM servo outputs.
When you power up the receiver (with servos connected), the servos move un-commanded to a position about one half of their throw in random directions. A few seconds later the transmitter and receiver engage, and then the servos move to their center and ready positions.
This problem even manifested itself on one of my planes such that the prop spins before the receiver and transmitter engage properly - I do not like that.
I just tested the XPS system with an XPS-J1 module and Nano receiver. It does the same thing: The servos move a little bit when I connect the battery to the receiver. But the Nano boots up so fast, maybe half a second for the servos to snap to their ready positions.
And, I repeated the test with an old Futaba 72MHz transmitter and receiver - it does the same thing! But, the receiver acquires the transmitter signal almost instantly (no boot up for analog electronics) so the spurious servo movement is hardly noticeable.
