sevans16,

It comes with a single Electrifly brand ES80 Micro Servo. See link for servo stats http://www.electrifly.com/miscproducts/gpmm1210.html

I ended up cutting out a servo opening in the bottom of the tail of the fuselage and used it as a tail wheel steering servo. It works great.

I used two JR 331 micro servos for the ailerons.
