bond the tail group with medium CA along
contact points between each other and the
fuselage.
72. Tack glue the sub-fin to the bottom of the
fuselage with medium CA. Center the fin on
the keel, with trailing edge flush with rear of
fuselage. Ensure fin is perpendicular to
fuselage, then bond to fuselage with medium
CA.
73. Solder a battery lead extension - PKZ3052 -
to the battery lead from the PKZ3351 receiver
brick, or simply cut the lead and solder in a
3-1/2 in splice from similar sized wire.
74. Refer to pushrod detail on plan to bend ends
to mate to servos on the PKZ3351 receiver
brick. Connect push-rods to servos, then
mount the receiver/esc/servo unit exactly as
illustrated on plan set using Du-Bro RC
double sided servo tape [DUB634]. Route
battery lead through holes in F1 and landing
gear pock.
75. Trim pushrods to length and attach to control
horns at control surfaces per diagram on
plans. Prior to setting final length of push-
rods (by securing parts “A” and “B” with heat
shrink), power up your radio equipment and
center the trims for channels controlling
elevator and rudder. Once centered at
transmitter, mechanically center the rudder
and elevator. Finally use a soldering iron to
shrink tubing joining overlap of push-rod parts
“A” and “B” then secure with a drop of
medium CA glue.
76. Route motor wire from PKZ3624 motor over
landing gear pocket. Connect motor to
receiver. Set motor and gearbox within slot in
F6. Secure gearbox with a drop of medium
CA glue under each “ear” to retain proper
right offset to thrust line.
77. Fold acetate windshield along perforations
and install in position indicated on plan.
Retain windscreen by carefully applying small
drops of medium CA along edges of
windshield.
78. The battery plugs into the lead extending from
the nose of the model. After connecting the
battery, slide it back into the opening so that it
rests within the nose of the model.
79. Mount the propellor [EFL9051] on the motor.
80. Mount wing with two #16 rubber bands.
81. Adjust balance of model by moving battery or
adding a bit of modeling clay within nose of
model. Model should balance on the spar,
1-5/8 in. from the leading edge of the wing.
Flight Control Setup
☐
Inspect wing for any warps that may have
worked their way in when covering, or while
the model was in storage, and remove prior to
flight.
DO NOT ATTEMPT FLIGHT IF WING
IS WARPED
. Lack of aileron control on this
model will make contending with a warped
wing very difficult.
FIX THE WARP.
☐
Center control surface then set direction, rate
of travel, and dampening (expo).
Rudder servo should be controlled by the
Aileron channel of your radio as rudder on
this model also controls roll of the aircraft.
Rudder should follow Aileron stick travel i.e.
moving Aileron stick to right should move
Rudder to right of aircraft. Likewise, left
Aileron stick input will move Rudder left.
Elevator servo will be controlled by Elevator
channel of your radio. Pulling back on the
Elevator stick should result in the Elevator
moving UP! Likewise, forward stick results in
the Elevator moving DOWN!
Rockette
™ is designed to be a very docile
flyer, therefore the flight controls are set up for
fairly minimal throws. The Rudder and
Elevator throws should be as follows:
Rudder Travel
Low Rate +/- 15 degrees
30% expo
High Rate +/- 20 degrees
50% expo
Elevator Travel
Low Rate +/- 15 degrees
30% expo
High Rate +/- 20 degrees
50% expo
The above exponential settings apply only to
computer radios.
Pre-Flight
Have and experienced pilot assist you with pre-
flighting your new model. Just like having
someone proof read something you’ve written,
having a second
fresh
set of eyes to inspect your
final product is often helpful at avoiding disaster.
