PRE FLIGHT CHECKS
- Is the model too heavy?
- Is the center of gravity (fore and aft) within
the range shown on the plans?
- Is the model balanced side to side? (right and
left wings of equal weight)
- Are all flying surfaces at the proper angle
relative to each other?
- Are there any twists in the wings? (other than
- Are they all securely attached? (i.e. hinges
glued, not just pushed in)
- Are the control throws in the proper direction
and amount? (usually indicated in the plans)
Have all linkages been checked to make sure they are secure?
- Are all snap-links closed?
- Have snap-links been used on the servo end? (They
are more likely to come loose when used on the servo)
- Have all screws been attached to servo horns?
Electrics Motor, Engine and Fuel (if
- Has the motor / engine been thoroughly tested?
- Are all engine screws tight?
- Has the motor / engine been run up at full
throttle with the plane's nose straight up in the air? (To make sure
it won't stall when full power is applied on climbout)
- Is the fuel tank level with the flying attitude
of the plane?
- Is the carburetor at the same height (not above)
as the fuel tank?
- Is the fuel tank klunk in the proper position and
- Has a full range check been performed?
- Has the flight pack charge been checked with a
- Have the receiver and battery been protected from
vibration and shock?
- Is the receiver's antenna fully extended and not
placed within a fuselage with any sort of metallic covering?
- The checklist should be gone through again, with particular
attention to the areas that were worked on or repaired.
Before EVERY Flight
Start the engine (if applicable) and test the entire throttle range.
Run it at full throttle with its nose in the air for 15 seconds or
Check the receiver flight pack with a voltmeter to ensure enough
- Check the control throw direction for all
surfaces. It's very easy to do a repair or radio adjustment and
forget to switch these.
