In my Taranis with OpenTX 2.2.1 I had sbus configured to send frames every 7ms to its DragonLink Tx module. At 7ms I had occasional flaky operation with a Navio2 flight controller and Arduplane 3.8.4.
What I mean by flaky is that about every third time I booted the transmitter and the plane, no RC link was made. Most of the time a power cycle of either the Tx and or the plane fixed it and enabled a good RC link.
When I put the sbus frame back to 14ms in the Taranis the system boots successfully just about every time.
Anyone have a similar experience?
