BrainCube Aeromodels - Fugly Construction Manual 27
Balance
Test Flight
90
The stability of any aircraft depends on it’s balance. Once your
Fugly
is fully finished, mount the battery
and close the hatch. Using your finger tips, one under each wing right next to the fuselage, find the
position where
Fugly
remains horizontal. This is the balance point. Move the battery forwards or
backwards until the balance point is
90mm
from the leading edge of the wing. You may have to add
ballast to the nose depending on the equipment you have used. Once you have found the correct battery
position, mark the battery tray so that you can easily replace the battery at the correct position.
Once you are comfortable flying
Fugly
, you can carefully move the balance
point backwards. This reduces stability, and increases the sensitivity to the
controls. Make sure you do this gradually - if too far back,
Fugly
will be
very hard to control.
Congratulations, your
Fugly
is ready to fly! If you are not an experienced model pilot, we recommend you
ask one from your club to test fly the plane for you to trim it out.
Before the first flight, make sure you do a range check of the radio with the motor running and a friend
holding on to the tail. Make sure you have the fail-safe set to kill the throttle if your radio has that
capability. Make sure that all the controls move in the correct direction and are centred when you release
the sticks.
Whilst
Fugly
can handle quite a breeze, for the first few flights try and stick to calm weather.
We hope you have enjoyed building your
Fugly
, and that you have great fun flying it. If you have any
feedback for us, good or bad, need spare parts, or just want to send us a photo for our Facebook page
