What size servo arm are you using for the tail servo

[CustomPC]

Hi, i'm just wondering what size servo arm people are using on their tail servos?

The text manual says 13-15mm but on my setup the short arm doesn't utilise the entire travel of the pitch slider.
The pictorial manual shows the large futaba wheel which is 19mm which can utilise the full travel of the pitch slider.
The futaba + arm with holes at 16.5mm gives me about 95% travel of the pitch slider.

Is there a reason why the manual suggests the use of a shorter arm?

I am using a round wheel on mine that keeps the pushrod level from the servo side to the bellcrank side that is going to the rudder pushrod. I see no problems with this setup and I chose the particular length that would do this (keep it level).

Raja, I came to the same conclusion myself and had already fitted the large wheel

I haven't flown it since installing it so i'm itching to find out how it goes.
