View Full Version : Swash ball link setup

I have a question regarding the head/swash setup for the new 600 pro 3GX system.

On every other FBL setup I have seen or done for the 500/600 ESP 3G setups, the balls that the mixing arms/swash driver connect have a longer standoff than do the balls that the blade grip links mount on. This was a discussion question that was covered in a different thread and answered as to the "why" Align does their head/swash setup this way. OK, short balls go to blade grips, and long balls go to mixing arms/swash driver.

I just saw my first 600 pro, and the way the builder had it set up was just backwards. He had the shorter standoff balls connected to the swash driver/mixing arms and the longer standoff balls going to the blade grips. I asked him this question, and was told that's the way the Align manual said to do it.

Is this a complete reversal for the 600 pro/3GX system. Obviously, I can't get a manual on the heli yet so I can't verify the info. So, thought I'd throw this out and see what others are doing.

FWIW, I can't really believe the small difference between the ball standoff lengths can really make that much difference in geometry of flight characteristics.

Thanks.

Manuals are available for download and on the fbl version the links to the grips use larger balls than anywhere else on the heli so hard to screw it up. Small changes do add up, I'll post the link to the vbar geometry calc and you can experiment.

Where are the manuals for the 600 pro?

Hi guys,

I believe the reason they used the balls with the longer standoff in the inner swash for the links that go to the grips is, Align first thought to use the inner holes of the servo horns rather than the outer holes later recommended in the manuals that followed the first release. Using the outer holes of the servo horns, you should now use the short linkage balls in the inner swash, and longer balls in the outer to increase resolution. That isn't the case if the inner holes of the servo horns are used, but you know the famous binding/interference problem that exist using the inner holes of the servo horns. Actually, now that most are using the outer holes of the servo horns, many are changing the swash balls to increase the resolution.
