What is the servo horn radii for the D3 FBL head to maintain the optimal FBL head geometry?

It's going to be in the 10-12 mm range, but the exact diameter will depend on the FBL system used.

I am now using 10mm radii (small round JR horn), but I can only achieve red light in adjusting the optimal FBL geometry at 6 degree in BeastX. In order to see the blue light, it will have to be 7 degree.

There are 3 holes on the FBL grip, and the hole I am using is on the outermost. Will that work if I use middle or the innermost one?

Im using 12.5mm, but 11-12 is normal.

For the love of the hobby

Then there is something wrong with my setup. If I use 12.5mm, then definitely, I will not be able to see even the red light.

Rudy,

Going in on the pitch arm is probably going to increase throw more than you want. I would go out a little on the servo wheel, custom drilling if needed.
