The following items should be checked regularly, at least before the first flight every flight date. It is recommended that most items be checked after each flight date, at home, so there will be no sunrises at the field next time out. Do not fly aircraft that does not pass all of these criteria.
Propeller & spinner secure - propeller properly balanced & undamaged - Do not use a damaged propeller, use the right size for your engine, otherwise you might run into high/low RPM which is bad for your engine.
Engine bolts secure to mount - Mount secure to firewall if not, make sure you tighten it- you can put few drops of expoxy or glue to hold in place.
Fuel tank secure, preferably in foam rubber - Tank clunk free when rotated 360 degrees.
Receiver, battery, all servos secure - Receiver in rubber - Wires clear of all moving control horns & pushrods - Antenna clear of servos.
Minimal free play in servo horns & pushrods - Control horns secure - Clevis' secure with safety retainers.
All control surface hinges secure (especially ARFs) with minimal gap - Free movement (no binds) all control surfaces - Rudder, elevator, ailerons
Throttle travel, idle to full - Shut off travel OK - No servo bind at full throttle (nothing drains a battery more than a servo bind.)
Nose wheel straight, at least sensitive position - Roll test on pavement ( for tricycle Airlanes)
Aileron servo connected - Retainer or baffle to keep aileron wire from entangling in aileron rods.
Rubber band quantity & installation - Do not use old or used rubber bands. Recommended installation: 2 criss-cross, 6 straight (3 each side), 4 criss-cross. Buy the one for RC Airplane, not the normal one.
Balance empty (no fuel) - Do not fly a tail heavy aircraft. Remember, a nose heavy plane flies sluggish; a tail heavy plane usually only flies once.
Receiver battery voltage - Do not operate below 4.9 volts. So remember, charge your battery at-least 8-10 hours in advance.
