Hi Bob, I have used JR, Futaba, and Hitec analog and digital servos with the Futaba decoders on many planes with no issue. This was the first time I have tried Savox and I wanted to use them as they have the same output shaft spline (25t) as Futaba. I have used SBus and SBus2 Servos from Futaba as well on installations, so no real reason except possibly the price being significantly lower for more torque and speed in a much better case size to fit the Avanti XS.

The XS called for JR 3401/3421 size servos and well as I'm sure you know they are really hard to get and getting worse as JR Japan shuts down plant after plant with moving and other assorted things. In any event, I have another of these planes at my winter home and I had the same Savox servos sent there too, so I really would like to solve the issue, but I will be testing the worst location on boot with a Futaba servo and disconnecting the other SBus lines to allow for a true testing of the Savox's, hopefully this weekend.

I just really wanted to see if anyone else had run into this yet.
