hobby servo - max angle

hey
i recently bought this servo here to learn some basics about servos

http://www.hobbyking.com/hobbyking/store/__9549__turnigy_tg9e_9g_1_5kg_0_10sec_eco_micro_servo.html

all i get is a max angle of a bit less than 90°.

is this it? i cant find any specific tech details about this type.
