In addition to the above suggestions:
-check all control horns to insure they are secure
-check all clevises/connectors/wheel collars that they are secure and the retainer is in place (if applicable)
-check servo arm screws that they are secure
-ensure all control surfaces are neutral with power on and Tx sticks at neutral and there is no binding of the servos
-make sure Rx and battery are secure and that battery is charged
-make sure the clunk "clunks"
-make sure no leads such as Y-Harness or servo extensions will be in the way of the servo arms
-inspect prop for cracks, chips
-check prop nut and spinner
-check Tx battery voltage
-do a thorough preflight to ensure all control surfaces respond appropriately to the stick movement and there is sufficient travel

You probably already know all this but it's just some things I always check especially on a new plane before the first flight.
