Keeping your aircraft in perfect shape
Precautions
1) Eliminate the use of ALL aggressive cleaning solutions and organic solvents, also the window
cleaning spray, benzene, acetone, aggressive shampoos etc.
2) If you must use an organic solvent (acetone) on small areas remove certain glue leftovers or simi-
lar, the surface in question MUST be polished thereafter. The only section where polishing should be
avoided is the edge on the wing where the sealing gasket is applied.
3) When ying in regions with a lot of bugs in the air, you should protect the leading edges of the
airframe before ight (propeller, wings, tail) with Antistatic furniture spray cleaner: “Pronto (transpar-
ent), manufacturer: Johnson Wax (or anything equivalent) – Worldwide”, approximate price is only $3
USD / €3 EUR for a 300 ml spray bottle. Using such spray, do not apply it directly onto the wing but
into a soft cloth instead (old T-shirts are best).
4) After having nished with ight activity for the day, clean the leading edges of the airframe as
soon as possible with a lot of water and a drying towel (chamois, articial leather skin). This will be
very easy to do if you applied a coat of Pronto before ight.
Detailed handling (Airframe cleaning instructions)
Every-day care after ight
Bugs, which represent the most of the dirt to be found on the airframe, are to be removed with clean
water and a soft mop (can be also drying towel, chamois, articial leather skin). To save time, soak all
the leading edges of the aircrame st. Make sure to wipe ALL of the aircraft’s surface until it is com-
pletely dry at the end.
Clean the propeller and the areas with eventual greasy spots separately using a mild car shampoo
with a wax.
CATUION! Do not, under any circumstances attempt to use aggressive cleaning solutions, as
you will severely damage the lacquer, which is the only protective layer before the structural
laminate.
When using the aircraft in dicult atmospheric conditions (intense sunshine, dusty winds, coastline,
acid rains etc.) make sure to clean the outer surface even more thoroughly.
If you notice you cannot remove the bug-spots from the leading edges of the aircraft, this means the
lacquer is not protected any more, therefore it is necessary to polish these surfaces.
CAUTION! Do not, under any circumstances attempt to remove such bug-spots with abrasive
sponges and/or rough polishing pastes.
Periodical cleaning of all outer surfaces with car shampoo
Clean as you would clean your car starting at the top and working your way downwards using a soft
sponge. Be careful not to use a sponge that was contaminated with particles e.g. bud, ne sand) not
to grind the surface. While cleaning, do soak the surface and the sponge many, many times. Use a
separate sponge to clean the bottom fuselage, as is it usually more greasy than the rest of the air-
frame. When pouring water over the airframe, be careful not to direct it over the fuel reservoir caps,
wing-fuselage joining section, parachute rescue system straps and cover, pitot tube, tail static probe
and engine covers.
