Default Ele servo mounted out frame?

See a post here where the guy says to notch the frame and mount the ele servo outside the frame.
I asked for details on this but the post was never added to.
Can anyone give details of this and the reason.new to the Pro.

Not exactly sure, but there was an issue on the earlier Sport model with the servo arm hitting the TT gear. The only other reasons I can think of are servo ball alignment with the main shaft or ease of servicability.

I put my servo on the tail for easy service and tail centering

I think it's just for easier mounting. I believe the ball goes on the outside of the servo arm instead of the inside of the arm now. As long as geometry stays the same, there should be no reason not to mount it on the outside.

I installed the servo outside of the frame, reason is ease of servicability. As mentioned, the ball goes on the outside of the servo arm instead of the inside of the arm. In case you strip the gear of the servo it's far less effort to repair.

+1..me too...i just used 2x steel washers from a set of skids to make sure the servo stays flat against the side frames.
you still can easily service the servo while its mounted inside too..just undo the back screws and pop out the servo by pushing the output shaft back through the casing.
kinda makes no difference unless you want to get at the top casing i suppose.
