Step 8
Replacing the Propeller
1. Using a #0 screwdriver, remove the two screws
installed in the front of the spinner. Remove the
spinner cone and place it aside so it does
not get lost.
2. Remove the pins installed in the prop blades. Set
them aside with the spinner cone so they do not
become lost.
3. Replace the prop blades and reinstall the pins.
Make sure the pins are flush when installed,
otherwise the spinner cone will not install.
4. Reinstall the spinner and confirm it is properly
seated. Reinstall the screws in the front of the
spinner.
Step 7
Flying the Radian
Always choose a wide-open space for flying your
ParkZone Radian. It is ideal for you to fly at a flying
field operated by an AMA chartered club. If you are not
flying at an AMA approved site, always avoid flying near
houses, trees, wires and buildings. You should also be
careful to avoid flying in areas where there are many
people, such as busy parks or school yards. Always
follow local ordinances. We recommend only flying
your Radian in light winds.
Note: The AMA does not sanction flying fields, they
charter clubs who then operate their own flying fields
according to AMA guidelines.
Prior to each flight
• Always make sure your Radian is properly trimmed.
• Always make sure the receiver, ESC and battery
are properly secured.
• Always verify the propeller is on securely.
• Always ensure the servo reversing switches on the
transmitter are set correctly.
• Always verify the dual rates switch is set at where
you plan on flying. We recommend LOW rates for
your initial flying. The Radian is very maneuverable
on high rates and requires a lot of experience to
handle properly.
Center of Gravity Location
The center of gravity on your Radian should be located
approximately 2-1/2” (63mm) behind the leading edge
of the wing, when measured against the fuselage. This
CG location has been determined with the ParkZone
1300mAh 11.1V Li-Po battery installed.
Note: The power system installed in the Radian is
designed for climbing use in bursts (50% operating
time or less). It is not intended to run full throttle for
long periods of time. Not following this direction may
result in reduced life of the power system.
After flying, it is important to recharge the Li-Po battery
pack included with the Radian. The Li-Po battery pack
should always be stored at least 70% charged to
prevent damage to the battery pack.
