I have a Futaba 6XAS radio system channel 24.
My problem is when I switch between HI and LOW rates my
elevator moves up 1/16"-1/8" with the trims centered and no stick input.
It moves up when I switch to high rates then back down when I go to low rates.The only mix I have turned on is for the ailerons to be used on seperate channels.
tried hi/lo rates on 1 and/or 2 switches does the same thing.
Any help or advice is greatly appreciated.

Thanks
