They will be plenty strong enough for that plane and if they are anything like the HXT900 from hobbyking, they are a good servo.

dunno about better, I just tend to do more bulk shopping from HK and these fit the bill just fine.

FYI, the only 1 I had a problem with was my fault! I hooked all the control linkage up, before centering the servo. When i plugged in the battery, the control arm was 90deg off and it went to center against the control surface and ground the gears into dust before I could figure out what was happening.

How do you center a servo???

SERVO - 9g TP SG90 Sub Micro Servo

TP SG90 9 gram Sub Micro Servo
The TP SG90 is similar in size and weight to the Hitec HS-55, and is a good choice for most Parkflyers. I have this servo installed in most of my models, including my GWS Slow Stick, E-Flite Mini Edge, GWS Corsair, Simple Stik, GWS Beaver, and World Models 48" Piper Cub. If you are looking for a servo that won't break the bank, yet gets the job done reliably, consider the TP SG90.
The TP SG90servo weighs 0.32 ounces (9.0 grams). Total weight with wire and connector is 0.37 ounces (10.6 grams).
The TP SG90 has the universal "S" type connector that fits most receivers, including Futaba, JR, GWS, Cirrus, Blue Bird, Blue Arrow, Corona, Berg, Spektrum and Hitec.
The wire colors are Brown-Red-Orange: Red = battery positive Brown = battery negative Orange = signal

TP SG90 Specifications:
Dimensions (L x W x H) = 0.86 x 0.45 x 1.0 inch (22.0 x 11.5 x 27 mm)
Weight = 0.32 ounces (9 grams)
Weight with wire and connecter = 0.37 ounce (10.6 grams)
Stall Torque at 4.8 volts = 17.5 oz/in (1.2 kg/cm)

Let me add something to what Steve said. After the servo centers, remove the servo arm, if necessary, and place the servo arm at a 90 degree angle to the servo. It is better if this is done without any linkages to the control surfaces attached or you will end up like Paul (pbert1975) with servo gear powder.

Now they are centered and ready for the linkages.

If the arm is not exactly 90 degrees to the servo, you can use the transmitter trim to center them.
