There's a pretty good chance I'm going to need more weight in the tail of my plane, due to larger motor and batteries. The plane has cutouts for side-mounted elevator servos, however my mini-servos are mounted inside the stab. So my options are:

1) Mount the rudder servo in the tail and move the batteries forward, creating more room for adjustment. This eliminates pull-pull and uses a direct push-pull linkage.

2) Use lower capacity batteries (4000mah instead of 5000mah) to lose weight in nose. This will cut down valuable practice time for this noob.

3) Buy bigger servos for the elevator (I have some pretty good Airtronics 94761 mini digitals in there now - don't need a performance upgrade).

3) Add a few grams (<20) of lead to the tail.


Is there any disadvantage to a tail mounted rudder servo with a quality, direct linkage?
