MANEUVERS
Fly general circles and
random maneuvers
Random maneuvers
From straight flight
chop throttle quickly
From level flight roll to
45-degree bank and
neutralize controls
Into wind, do open loops,
using only elevator
Repeat tests doing
outside loops from
inverted entry
Into wind, do tight inside
loops
With wings level, pull
to vertical climb and
neutralize controls
OBSERVATIONS
Try for hands off straight
and level flight
A Too sensitive, jerky
controls
B Not sufficient control
A Aircraft continues level
path for short distance
B Plane pitches nose up
C Plane pitches nose
down
A Continues in bank for
moderate distance
B Nose pitches up
C Nose drops
A Wings are level
throughout
B Yaws to right in both
inside and outside
loops
C Yaws to left in both
inside and outside
loops
D Yaws right on insides,
and left on outside
loops
E Yaws left in insides and
right on outside loops
A Wings are level and
plane falls to either side
randomly
B Falls off to left in loops
Worsens as loops
tighten
C Falls off to right in
loops Worsens as loops
tighten
same path
inside loop
C Nose tends to go to
outside loop
CORRECTIONS
Readjust linkages so that
Tx trims are centered
If A, change linkages to
reduce throws
If B, increase throws
If A, trim is okay
If B, decrease downthrust
If C, increase downthrust
If A, trim is good
If B, add nose weight
If C, remove nose weight
If A, trim is correct
If B, add left rudder trim
If C, add right rudder trim
If D, add left aileron trim
If E, add right aileron trim
If A, trim is correct
If B, add weight to right
wing tip
If C, add weight to left
wing tip
If A, trim is correct
If B raise both ailerons
very slightly
If C, lower both ailerons
very slightly
51
If B, add weight to right
wing tip
If C, add weight to left
wing tip
AILERON
RIGGING
With wings level, pull
to vertical climb and
neutralize controls
A Climb contini
same path
B Nose tends to
ies along
goto
If A, trim is correct
If B raise both ailerons
1 Engine thrust angle and C G interact Check both
2 Yaw and lateral balance produce similar symptoms Note that fin may be crooked Right and left references are from the plane's vantage point
