Towhook (Glider Version) (Fig. 53)
• Keep the recommender CG position 78 – 82 mm be-
hind the wing leading edge.
• Set the towhook 10 mm in front the CG for the first
flight.
• You have to loose the front screw in order to move the
towhook.
Power System Installation (Electric Version)
(Fig. 54-56)
• Fit your motor using appropriate screws to the fire-
wall; secure the ESC and power pack using Velcro tape
into the cockpit. With your RC set on test whether the
motor rotates in the correct direction (counter cloc-
kwise when looking from the front) If it not the case,
change the setting of your ESC or swap any two of the
FLYING
Be sure you are using fully charged batteries. Now (and
before any further flight again) check correct function
of whole radio equipment, motor and moving of cont-
rol surfaces. Be sure any part of flight equipment cannot
move during flight. We strongly recommend making a
range check (see your radio instruction manual for de-
tails).
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. Fa-
cing 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 powerful 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 sur-
faces; set length of pushrods to bring back trim tabs
on your transmitter to central position if necessary
(we strongly recommend 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 model 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
three cables between the motor and ESC. Fit 30 or 32
mm spinner with blades corresponding to your motor
and battery set-up.
Spoiler (Fig. 57)
• The servo must be located as high as possible – as clo-
se 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
approx. 50-60% of full throttle flies straight without
turning, descending or ascending (if your RESCO alre-
ady tends to ascend you will have to increase motor
down thrust), turn the motor off and test RESCO's
gliding characteristics.
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 increa-
se 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 optimal
setting - safe climbing and good gliding - it is a compro-
mise, of course. You might find useful programming a
spoiler->elevator mix (if your radio allows) that will eli-
minate the nose pitching when the spoiler is deployed.
In general the CG position should be located between
78-82 mm behind the wing leading edge. By moving
the CG back you get better gliding performance whilst
reducing the stability. It makes your model more sen-
sitive 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. Beyond 82 mm
the increasing lack of stability prevails over the gain of
gliding performance.
Enjoy your new RESCO, have a ball!
