FBL Links what measurements?

[esmoglo]

Ok well my X50 Belt and FB heli that I got used has undergone the transformation to a FBL head and TT tail. Now that its 98% completed I can’t seem to find measurements for the upper links that go from the blade grips to the swash. Can anyone advise what measurements they have come up with?

This is what I have on my the bird:
Align DS610’s on Cyclic
Futaba BLS251 on the tail
ACE 1213 throttle servo
Align 600 3G blades
Align carbon tails
Durlite 6V Regulator with on/off switch
Full size V-Bar blue line with Pro software
Spektrum bottom plate sensor on the motor
Red Line 53
Red Line black pipe
TT FBL head
TT Torque tube tail

It should see some air time this week I hope…

84.3mm should get you close to zero degrees at the blade grips if the bell cranks are all zeroed out and level.

Here are some pics to show proper positioning of the servo arms and bell cranks. Hope this helps. The X50B I had was an awesome bird.

Any idea about the play on the grips?

I have the same play. I have tried to get rid of it and can't. The thrust bearings are installed right, and the heli flies awesome so I gave up. If someone knows how to fix it I would love to know.

Cool I am glad its not just me then, I took them apart 3X's it was driving me nuts.

I added one extra shim between the thrust bearing and radial bearing on one side, and it helped a little.
If I added an extra one to the other side then it made the grips too tight, and they did not rotate smoothly.
