tighten the nut and secure the hook. The forward hole is
recommended for starting out as it will provide mild
launches for first flights. Later, the hook may be moved aft
for more aggressive, higher launches.
❍
3. Cut off two of the barbs from the pegs on the tail skid.
Drill 1/8" [3.2mm] holes through the bottom of the fuselage
for the prongs. Then glue the tail skid into position.
Check the Control Directions
❍
1. Turn on the transmitter and receiver and center the
trims. If necessary, remove the servo arms from the servos
and reposition them so they are centered.
Don’t forget to
install the screws that hold on the servo arms.
❍
2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If necessary,
screw the clevises on the pushrods in or out to center the
control surfaces.
❍
3. Make certain that the elevator and rudder respond in the
correct direction as shown in the diagram. If necessary, use the
servo reversing function in the transmitter to reverse the servos
so they respond in the right direction.Be certain the elevator and
rudder have remained centered. Adjust if necessary.
Set the Control Throws
Use a ruler to measure and set the control throw of the
elevator and rudder as indicated in the chart that follows. If
your radio does not have dual rates, we recommend setting
the throws at the
low
rate setting.
Note:
The rudder throw is measured at the bottom of
the rudder.
Balance the Model (C.G.)
At this stage the model should be in ready-to-fly condition
with all of the systems in place including the servos, switch,
battery and receiver.
More than any other factor, the
C.G.
(balance point) can
have the
greatest
effect on how a model flies, and may
determine whether or not your first flight will be
successful. If you value this model and wish to enjoy it for
many flights,
DO NOT OVERLOOK THIS IMPORTANT
PROCEDURE.
A model that is not properly balanced will
be unstable and possibly unflyable.
IMPORTANT:
The Tower Vista 2m sailplane has been
extensively
flown and tested to arrive at the throws at
which it flies best. Flying your model at these throws will
provide you with the greatest chance for successful first
flights. If, after you have become accustomed to the way
the Tower Vista 2m sailplane flies, you would like to
change the throws to suit your taste that is fine. However,
too much control throw could make the model difficult to
control, so remember, “more is not always better.”
These are the recommended control surface throws:
High Rate
Low Rate
ELEVATOR:
5/8" [16mm] up
3/8" [10mm] up
5/8" [16mm] down
3/8" [10mm] down
RUDDER:
1-1/2" [38mm] right 5/8" [16mm] right
1-1/2" [38mm] left
5/8" [16mm] left
