the stronger lift. Thermals are swept along by the
wind so allow your circle to drift downwind with the
thermal. Be careful when following a thermal
downwind though as you still have to be able to make
it back to the field!
If the sailplane is flying along and all of a sudden turns
by itself, it has probably flown near a thermal. Keep in
mind that thermal will have tendency to turn the plane
away, so make a 180 degree turn and fly back towards
the thermal. If you don’t quickly encounter lift start
searching around that area. If you find the thermal,
follow the procedure outlined above to take advantage
of it.
Thermals can be generated at any time of the day, but
the strangest thermals are usually produced when the
sun is directly overhead 10:00am to 2:00pm seems to
be the best time to find the strongest thermals.
If you find yourself getting too high or you’re having
trouble getting out of a strong thermal. DO NOT dive
the plane to lose altitude. This will very quickly over-
stress the airframe and blow the wings off the plane.
The easiest and safest way to quickly lose altitude is
to apply full rudder (either right or left) and full up
elevator. This will put the plane into a tight spin that
will normally not over-stress the airframe. This is
especially useful if the sailplane gets sucked into a
cloud or gets too high to see. The spinning action will
give the sun a better chance of reflecting off of the
wing and catching your attention.
As you might expect, with all this rising air, there must
also be some sinking air. This sinking air is the
sailplane pilots enemy and one of the factors that
really make soaring challenging. “Sink” as it is
referred to, is usually not as strong as the nearby
thermals, but is can quickly put a sailplane on the
ground. Sink in one of the reasons, you have to be
very careful when chasing a thermal downwind. If you
encounter sink, immediately turn and fly 90 degrees to
the direction of the wind. Apply a little down elevator
to pick up some speed and get out of the bad air as
quickly as possible.
Safety Precautions
You as the pilot of this radio controlled model are
responsible for any accidents that may occur during its
use. We recommend that you fly your model at a
model club field which is specially set up for model
flying. But always be sure that you operate the model
in a safe and careful manner and observe the
Following Suggestions:
1. Do not fly your model close to buildings, power
lines, roads, or other obstacles.
2. Do not fly in congested areas such as parks or
occupied playing fields. Select wide, flat and open
area to fly with no obstructions and plenty of room
for learning to fly.
3. Do not fly without help from an experienced model
pilot until you have learned how to fly. Your local
model club or hobby shop can recommend an
instructor if you do not already know one.
4. Always check for other modelers in the area and be
sure that your frequency is not in use by someone
else which might cause you model to crash.
Always observe frequency control systems at
flying fields and wait your turn to fly.
5. Never fly your model directly toward spectators,
autos, other modelers or their models.
6. Always abide by the rules for model flying provided
by your club and the governing agency for model
aircraft in your country.
Congratulations
Now that you have completed the assembly of your E-
Hawk model we feel that have a very capable and
good looking 2-meter electric sailplane. We hope that
you will enjoy this model and get many hours of flying
pleasure from its use. Thank you for purchasing this
E-Hawk from Thunder Tiger and we look forward to
providing you with other great R/C products in the
future.
