E9 FBL Geometry

[rchaas]

So, I am going to convert one of my N9's to E9, FBL. I'll be using a Bonta head and Mikado VBar 4.0.

I understand that the geometry needs tweaking because of the asymetric swash bell cranks. How have you all adjusted for this? Shorter servo arm, or modified aluminum bell cranks, or both?

For those that have modified the bell crank, what dimensions did you use? Same question for servo arms?

Thanks.

I am going to go to a FBL head on my N9 but will take a different route. Because of the bellcrank "gain" I will keep the small arms on the main blade grips. The link that currently connects to the flybar assembly will be connected to the head block. This will give a reduction in "gain" that should compensate for the bellcranks. This also saves money. :-)

What do you think of the idea?

We did some tweaking on the Synergizer at IRCHA. Stock geometry, 10mm servo arms, FBH rotorhead,
V Bar 5.0 flys like a champ..
