Take out the glow plug and put a few drops of ARO (After run oil) into the cylinder and turn the engine by hand to get everything coated and lubed.
Then you'll want to give it a few short spins with the starter to make sure everything is turning freely. Put in the glow plug and check the compression.
Check all your fuel lines for drying or leaking, you might actually want to replace them since it's only a buck a foot for the tubing.
Make sure all your batteries are fresh or fully charged and THOROUGHLY check the movement of your servos to avoid a wide open throttle run-away.
Drive around slowly to give it a chance to warm up, then make any necessary adjustments to your tuning and idle.
Enjoy it!
