RE: Trim memory with Futaba T6XA
Yes, the Futaba T6XA has a trim memory function which can be accessed via the "TMEM" screen.
It is still best to trim your airplane MECHANICALLY via the servo arms/clevises for straight and level flight with the trims centered. Relying too heavily on electronic band-aids can result in a model with peculiar control responses.
The analog trims on the T6XA(S) are just fine. It was a sad day when some engineer got the bright idea to start using "digital" trims. Yuk.
