rewall; secure the ESC and power pack using Vel-
cro tape into the cockpit. With your RC set on test
whether the motor rotates in the correct direction
(counter clockwise when looking from the front) If it
not the case, change the setting of your ESC or swap
any two of the three cables between the motor and
ESC. Fit 30 or 32 mm spinner with blades correspon-
ding to your motor and battery set-up.

FLYING
Be sure you are using fully charged batteries. Now (and
before any further flight again) check correct functi-
on of whole radio equipment, motor and moving of
control surfaces. Be sure any part of flight equipment
cannot move during flight. We strongly recommend
making a range check (see your radio instruction ma-
nual for details).
The first flight: Wait for a calm day. Fly only on a safe
site as a RC club flying field. Glider will be very happy
on your favourite slope on a calm day. The very light lift
will allow perfect fine trimming out.
Glider:
Switch your transmitter and then the receiver on and
check all the working systems one more. Facing INTO
the wind hold your transmitter in one hand; grip the
model in the other hand near the centre of gravity.
Hold it at head level and give the model a fairly power-
ful push exactly into wind; wings level, nose slightly
down. Your model should now glide in a long, flat and
straight path without needing any help from you. Use
the controls gently if necessary, and adjust the trim
tabs until your RESCO glides above described way.
Now check the position of control surfaces; set length
of pushrods to bring back trim tabs on your transmi-
tter to central position if necessary (we strongly re-
commend doing it in any way). Check again gliding
of your RESCO. Now you are ready to make your first
bungee launch. Always use a bungee set appropriate
to the size (100-150 m) and weight of your model!
Electric version:
Switch your transmitter and then the receiver on and
check all the working systems once again. Launch your
RESCO with throttle fully open INTO the wind. During
climbing be gentle on the controls, try to keep the mo-
del flying into the wind until you have about 100-150
metres of altitude. Climb slowly - too steep climbing
may cause the model will stall and fall to the ground.
You are at 150 metres - this is time to trim out your
RESCO at full power. After everything is OK - it means
the model at approx. 50-60% of full throttle flies strai-
ght without turning, descending or ascending (if your
RESCO already tends to ascend you will have to incre-
ase motor down thrust), turn the motor off and test
RESCO's gliding characteristics.
close to the spoiler as possible.
• Install the servo using double sided foam tape.
Recommended Control Surface Throw, CG Po-
sition (Fig. 58)
• CG Position: 78-82 mm
• Rudder: ±60 mm
• Elevator: ±10 mm
• Spoiler: -40 mm
• Brake->Elevator mix: -5 mm elevator at full spoiler
Keep your RESCO into the wind and observe its flight.
If turns without power right (although under power it
kept the straight direction) it will be necessary to incre-
ase motor right side thrust and vice versa. If descends
too much without power (although under power it
kept the level flight) you will have to increase motor
down thrust (assuming the centre of gravity is correct!
- check it after landing).
Final Fine Tuning
During next flights trim out your RESCO to find opti-
mal setting - safe climbing and good gliding - it is a
compromise, of course. You might find useful pro-
gramming a spoiler->elevator mix (if your radio allows)
that will eliminate the nose pitching when the spoiler
is deployed. In general the CG position should be loca-
ted between 78-82 mm behind the wing leading edge.
By moving the CG back you get better gliding perfor-
mance whilst reducing the stability. It makes your mo-
del more sensitive on controls and increases the model
reaction on thermal. The back CG position makes the
model more difficult to fly and requires more attention
from you, while a nose heavy model is easier to fly but
you will lack the performance. We recommend starting
with the CG at 78 mm behind the leading edge. Bey-
ond 82 mm the increasing lack of stability prevails over
the gain of gliding performance.
Enjoy your new RESCO, have a ball!
