Set-up and flying tips
-
The CG range for the YAK-54 EXP starts at the front
of the wing tube and extends to the rear of the wing tube. There is plenty of
room on the battery tray to move your battery to achieve this CG location.
Depending on your flying style you can adjust the position of the battery to
alter the CG to accommodate your preferences. For this type of aircraft
where I am going to predominantly fly aggressive 3D I typically set the
airplane up with a neutral CG, meaning that when the aircraft is flown
inverted straight and level it requires no down elevator to maintain altitude.
If your flying style leans more toward precision aerobatics then I recommend
setting your CG using the 45 degree line test. Fly the aircraft from left to
right or right to left, whichever direction you are more comfortable with at
3/4 to full throttle. Pull the aircraft to a 45 degree up line and establish this
line and immediately roll the aircraft inverted. Establish this line and let go of
the elevator stick. Ideally the aircraft will continue to track on that 45 degree
line for several hundred feet before slowly starting to level off. Adjust the
position of your battery to achieve this flight condition. Once satisfied with
the location of your CG scribe a mark on the battery tray so that you can
position the battery in the
same location each flight and achieve the same feel
and flight characteristics each flight.
