For a Raptor 30 you'd be wasting your money on 100 dollar servos, even the 9252's would be over kill. Good servos are nice, they center consistently, in a helicopter that means you arent chasing the trims all the time to get a stable hover.

Also check around, Ricks http://www.ronlund.com and Heliproz http://www.heliproz.com sell Futaba stuff for less than they advertise but you have to call them or email them, for example the going price for 9252's is 69
