9Z - Twin Elevator Problem
Hello,
I have setup my plane with 2 elevator servos in the 9Z using the Ailevator function, however, when I move the stick, the elevator half which is connected to channel 5 seems to be 'lagging' behind the other half then stops equally. This is what I have tried,
1. Ensure the pushrods are equal length
2. The control horn geometry is equal length / distance from hinge
3. Equal sub-trim on both servos.
4. ATV / AFRs are equal.
This is what I have noticed, when I yank the elevator stick fast, then the above 'difference' is noticeable, when I pull the stick slowly, it does not show. Also the movement of the elevator halfs are EQUAL at points.
The difference is noticed as I am using 1/4" balsa sticks stuck onto the elev. halfs to measure / setup, they are 12" long.
Is this normal? or is there some thing that I am missing?
All help is appreciated. Thanks !!
regards
Marcus

RE: 9Z - Twin Elevator Problem
What you see is normal. The two channels don't get transmitted at the same time. One is slighly later than the other..just enough that you'll notice it. It can't be eliminated. The 14MZ groups channels with the same function closer together to reduce it as much as possible, but it's present even in that system.
