E-flite Ascent PNP Assembly Manual
Control Throws
1. Turn on the transmitter and receiver of your Ascent
450 BL Park Glider PNP
®
. Check the movement of the
rudder using the transmitter. When the stick is moved
right, the rudder should also move right. Reverse the
direction of the servo at the transmitter if necessary.
2. Check the movement of the elevator with the radio
system. Moving the elevator stick down will make the
airplane elevator move up.
3. Use a ruler to adjust the throw of the elevator and
rudder. Adjust the position of the pushrod at the control
horn to achieve the following measurements when
moving the sticks to their endpoints.
Note
: Measurements are taken at the widest point
on the surface.

These are general guidelines measured from our own flight tests.
You can experiment with higher rates to match your preferred
style of flying.
Center of Gravity
An important part of preparing the aircraft for flight is properly
balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for
the Ascent 450 BL Park Glider PNP is 1–1

-inch (25–38mm)
back from the leading edge of the wing. Mark the location of the
CG on the bottom of the wing.
Please balance your model while it is upright with the
battery installed. With the model upright, lift the model at
the marks using your fingertips, or use a commercially available
balancing stand. The model will rest level or slightly nose down
when balanced correctly. Adjust the position of the motor battery,
or add weight to the nose or tail if necessary to achieve the
correct CG. Please understand that if you use a different Li-Po
battery than the one included, you need to rebalance the model
to verify the Center of Gravity.
