hey guys

i have the stock Perfex radio and servos on my inferno RTR buggy.
i want to upgrade the steering servo, and my LHS doesn't have any options to choose from. The best one they offer is the HITEC 645 MG HIGH TORQUE SERVO.

the specs are:

Three metal gears.
Dual ball bearings.
Metal 1st Gear
Speed: 0.24 sec/60 degrees at 4.8V
Torque: 106.93 oz/in at 4.8V (7.7kg/cm)
Length: 1.59" (40.6mm)
Width: 0.77" (19.8mm)
Height: 1.48" (37.8mm)
Weight: 2.11oz (60g)

What do u guys think? keep in mind it realy is pretty much the only high torque servo my LHS carries. Should i go for it?

thanks guys.
