3. † Starting with the front of the wing strut, attach
the bottom clevis to the lower strut bracket.
† Keep twisting the upper clevis till the strut fits
snug between the lower and upper attach-
ment points.
† When satisfied, attach the upper front strut
clevis to the wing
1. Using glass cleaner and a soft cloth, clean the
model surface thoroughly before applying
decals.
2. Cut the decal sheets apart in sections, as
needed.
Fold the decal in half, front to rear. Open at
the fold and place the decal on a flat surface.
The protective backing will bubble away from
the decal at the fold.
DECAL APPLICATION
† Adjust and attach the rear strut to the wing.
† Tighten all 2-56 hex nut to the clevises using
thread lock.
† Place a clevis clips on each clevis.
Throws
Use these control throws for the first
flights. Work your way up to more throw
movement when you are comfortable
with the Stinson.
Elevator 3/4” UP& Down
Ailerons 1/2” Up & Down
Rudder 1-1/2” Right & Left
When you have gotten comfortable
flying the Stinson slowly increase the
throws while still staying within your fly-
ing ability.
The Stinson was designed around
a 1.20 four-cycle engine these engines
will give you excellent performance.
Remember, a bigger engine is not
always better. Using a 15-8 to a 16-8
prop works well on these engines.
BALANCING AND CONTROL THROWS
CG Balancing
Balancing the Stinson is very important,
you might need to use weight depending
on the servos and engine that you use.
Start out with the balance point at 3”
back form the leading edge of the wing
next to the fuselage. This balance point
is a safe place for you to fly the Stinson
at. As you get comfortable you can move
the CG back further. The further you
move the CG the more wild the aerobat-
ics will become, BUT the more unstable
the Stinson will become.
