ENGINE MAINTENANCE
After each flying session:
Step 1
Fully drain the fuel from the tank.
Step 2
Start the engine and run it until the fuel is completely run out
of the engine.
Step 3
Try starting the engine three more times or until it will no
longer fire. This gets all the fuel out of the engine.
At the end of each flying session, several drops (about 10)
of after run oil (Evolution Engine’s Blue Block Rust Inhibitor,
EVOX1000) should be applied into the carburetor, and the
engine should be turned over for a few seconds with the
starter. This will prevent rust and corrosion.
Section 21:
Maintaining Your P-51 PTS Mustang
The following is a check list that you should follow
every time you have completed a flying session with your
P-51 Mustang PTS. Doing so will keep your aircraft in the
best flying condition.
Clean Up
After a long flying session with your P-51 PTS Mustang, you
will want to clean it up before loading it into your vehicle
to head home. Use a cleaner such as Windex or 409 and
a paper towel to wipe down the exterior of your plane,
removing the fuel residue. Remember, a clean plane will
last longer since the fuel won’t be allowed to soak into any
exposed wood.
Checking the Propeller
Check to make sure the propeller is tightly secured to
the engine. If not, remove the spinner and use a crescent
wrench to tighten it back down. If you have had any not so
great landings, you will want to inspect the propeller for
any damage. Small nicks and scratches can quickly become
fractures, causing the propeller to be unsafe for flight.
Always carry a few spare propellers so a damaged propeller
can be replaced at the field, increasing your flying time per
trip to the field.
Checking the Clevises
Inspect the aileron, elevator and rudder clevises to make
sure they are connected and in good working order. If you
find a clevis that is showing signs of wear or is broken,
replace it with a new clevis. Also check the nylon connectors
at the servo for any wear or damage. If they look worn or in
bad shape, replace them as well.
