14MZ Throttle Stick Cant go Mix

[sookainian]

Why is it like that ?

That's the lowiest i can go on my throttle stick, up to the 2nd white line.

But my Aliron and Ele i can go until the 3rd white line

That is normal for For at least the 9Z 12mz and 14mz maybe others.
There is a mechanical stop on the throttle stick that is removable.
But if you want to remove it the radio will need to be recalibrated.

Why Futaba does this, I have no clue.

But it is normal and intentional, just ignore it.
