The latest versions of these receivers do not encode sbus ch 17 frame lost and failsafe bits correctly. These should be bits 4 and 8 but are bits 16 and 32. i.e. framelost and failsafe should be a value i=of 12 but comes out as a value of 48.
I did raise this before but no reply - it can be very dangerous if relying on the sbus failsafe!!!
