FBL swash driver - how to line it up?

[fishface]

On the Align FBL helis, the swash driver for the FBL heads has to be positioned on the main shaft so that the driver arms are parallel to the feathering shaft, are there any tips/tricks to make sure that the arms are exactly lined up, or it it just a case of eye balling the swash driver arms against the outside edge of the head block to make sure they are in-line? I have been using the 'eye balling it' approach, but it just doesn't seem very scientific and wondered if I an missing something.

Thanks

eyeball it steve so long as the arms are in line with the main shaft thats cool

I line up the swash driver so the long links from swash to blade grips is parallel with the main shaft, this seems to work better on my 550 than sighting the swash drivers arms with the head.

hold a ball link on the upper swash plate between thumb and index finger, together with the elevator ball on the lower swash plate.
Then adjust, until the blade grips are exactly perpendicular or parallel to the body.

Even a couple of degrees of misalignment will cause noticeable wobble in abrupt cyclic moves.

Agreed- Eyeball and this gives a good result. I positioned it so the arms of the swash driver are horizontal at 0 degrees pitch at half stick, though I'm sure you have already done that. I was guessing at this as I bought the parts to make the head and had no instructions :P
