I also run the lanier ripper, and personally I love the plane. It is my first combat plane, and in fact its still my only combat plane. Use standard servos like the futaba 3004 servos on the elevator or throttle if you want. Im used an el cheapo expert mini servo which works for the throttle but, changed to a HS 85 regular geared servo as the expert died on me. You can use a HS 85 metal gear servo for the ailerons if you want however, you are not really gaining much from it, as its almost the same weight as a standard servo. Currently im using the OS 15 CVA on it with a mousse can muffler with great success. Although, its not legal for SSC use. One thing i could tell you is build the wing with the plastic leading edge protectors. It adds a great deal of strength to the wing, and if you have any misshaps the wing would survive with little damage.
