3.
Insert the wing dihedral joiner (a straight steel bar) in the hole built-in the root section of each wing panel and
join the two panels tightly together. Then, apply the supplied adhesive tape to make the joint seamless and
airtight.
4.
To mount the complete wing onto the wing saddle on top of fuselage, note first that there are two metal
dowels made inside the fuselage and two holes in the L.E. of the wing. Place the complete wing on the dowels
so as to let the dowels slip into the holes and the complete wing settled in place on the fuselage.
5.
Insert the two plastic hold-down bolts through the holes in the T.E. of the wing and let the bolts get into the
nuts built-in the wing saddle. Finally screw and tighten the two bolts to fix the wing in place.

Final check before flying
1. Check the alignment and symmetry of the Kit after final assembly.
2. Make sure that the servos operate. When the control sticks are in neutral, the servo horns and control surfaces
are also in neutral as well. Adjustment can be made by turning the clevis clockwise
or counter-clockwise to change the effective length of the control-rods so as to get the neutral position of the
control surfaces
3. Check the movements and direction of the elevator and ailerons.

4. There is one final step, and this is very important. In order to be controllable in the air, the Valbella 2000 must
balance properly. Make a mark on the bottom of the wing on each side of the fuselage 2 5/8" behind the front
of the wing. . Now try to pick up the airplane using only your fingertips positioned on the marks. If the tail
rises higher than the nose, you must add weight to the tail until the airplane will rest level on your fingertips.
If the nose rises you must add weight to the nose. Hobby shops and tire stores sell stick-on lead weights for
this purpose.
