The pre-covered film on ARF kit may wrinkle due to variations

of temperature. Smooth out as explained right.

* Use an iron or heat gun. Start as low setting. Increase the

setting if necessary. If it is too high, you may damage the

film.

Die Bespannung des ARF-Kits kann je nach Temperatur Falten

werfen. Glatten Sie diese, wie rechts auf der Abbildung ersichtlich.

Benutzen Sie ein Bugeleisen. Starten Sie in einer niedrigen Stufe,

un erhohen Sie diese nur wenn notwendig. Wenn das Bugeleisen

zu hei wird, beschadigen Sie die Bespannung.

Stabilizer

Trial fit each part before gluing . Be certain

that there are no gaps. If the parts will join,

but with a gaps, sand or trim the parts a

little at a time until the parts meet exactly

with no gaps.

When joining the stabilizer it is extremely

important to use plenty of epoxy (30 minutes)

Carefully slide the stabilizer onto the fuselage,

ensuring that they are accurately aligned,

Firmly press they are together, allowing the

excess epoxy run out. Using rubbing alcohol

and paper towel, clean off the excess

epoxy.

THE CENTER OF GRAVITY IS LOCATED 106 - 112mm BACK FROM THE

LEADING EDGE OF THE WING, AT THE FUSELAGE.

If the nose of the plane falls, the plane is heavy nose. To correct this, move the battery pack further back in the fuselage.

If the tail of plane falls, the plane is tail heavy. To correct this, move the battery forward or if this is not possible, stick weight onto the

firewall.

When balanced correctly, the airplane should level or slightly nose down when you lift it up with your fingers (or model airplane

balancer).

DO NOT try to fly an out-of-balance model !
