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.

Elevator

Low Rate: 5/8-inch (16mm) (Up/Down)

High Rate: 1-inch (25mm) (Up/Down)

Rudder

-inch (38mm) (Right/Left)

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.

1–1 / -inch

(25–38mm)

After the first flights, the CG position can be adjusted for your

personal preference.
