If you have carbon fiber, then by all means use them, or at least use 4-40 rods.

For elevator or rudder servos, use something that has around 80oz/in torque like the Hitec 605's. Stardard servos will be fine for the ailerons.

You might want to glue the canopy with RC-56 canopy glue instead of screwing it on as mine cracked where the screws went into the plastic. I had to order another canopy and I glued that one in and it has been fine since.

One other thing, I actually drilled through the metal hinges and pinned my rudder and elevator as my rudder came loose after a couple of flights.
