122.
As shown at the bottom of the preceding page, align each hubcap‟s round post to the round opening in the hub of each
wheel. Press the retaining clip at the end of the two remaining posts into their rectangular openings in the hubs.
(NOTE: A conservative modeler may also apply epoxy to ensure the hubcaps remain attached to their wheels.)
123.
As shown at the right, trim 2 pieces of blue plastic to fit around the cabane struts and
over the openings on each side of the fuselage. Attach these covers to the fuselage
with epoxy or thick CA adhesive.
124.
In the same manner, cover the rectangular opening on the right side of the tail.
125.
Trim, peal and stick
the markings as
shown at the right.

VII. SETUP AND ADJUSTMENTS
1.
For your first flights, set your PT-17‟s center of gravity (CG) at the Maxlok pin in the bottom of the top wing.
If necessary, move batteries and/or add weight to the nose or tail to ensure the CG is correct.
2.
Check the heat-shrink covering material‟s joints and surfaces; if necessary, carefully use a dedicated covering-material iron
and heat gun to secure the edges and to tighten any loosened areas. Recheck and retighten from time to time.
3.
Double-check servo centering, direction and end-point adjustments: If you fly mode 2, when you pull the right stick toward
you, the elevator should deflect upwards; push the right stick to the right and the right aileron should deflect upwards and
the left aileron should deflect downwards; push the left stick left and the rudder should deflect to the left as viewed from
the rear of the fuselage. Review your radio‟s instruction manual if you require assistance with any radio-related or
servo-adjustment questions.
4.
If you are using a Computer Radio: For initial flights set all linkages for near-max. possible deflections; then, soften the
aileron‟s and elevator‟s control throws by selecting 60% or more exponential (use 30% exponential for the rudder).
Initial settings if you are using a Non-Computer Radio:

Ailerons .................. +12 degrees

Trim adjustments: The ailerons and rudder will probably require no adjustments (you will probably be able to leave them
centered, as assembled); if you fly at fast (non-scale-looking) air speeds, be prepared to dial in some down-elevator trim.
VIII. PREPARATION FOR TRANSPORT AND FIELD SETUP
1.
To remove and store the wings:
a)
If you have anchor points on each side of the nose, release the wing-wire clevises at each side of the fuselage.
b)
Insert and tie string or use rubber bands to secure the
wooden wing supports between the top and bottom wing
panels near the root ribs.
c)
Remove and set aside the Maxlok pins that secure each pair of
left and right wing panels to the top wing‟s center section and
to the fuselage.
d)
Gently pull the wing panels outwards a few inches,
disconnect the aileron extensions from the Y-cable, and
set aside the servo extension safety clips.
e)
Continue to gently pull outwards on each set of wing panels
until the left- and right-side pairs of upper and lower wing
panels slide fully off their wing joiners.
f)
For safe-keeping, return the Maxlok pins into their openings
in the lower wing‟s center section and fuselage.
