The ParkZone Radian Pro is a follow-on to the Radian. Designed with the experienced sailplane pilot in mind, the Radian Pro is equipped with 5-channels
out of the box, including ailerons for a more precise soaring experience and flaps for more glide path control. This aircraft delivers flight performance that
you might expect from the traditional competition sailplane, without the construction work. Available in both Bind-N-Fly® and Plug-N-Play® completion
levels, this plane can be ready to fly in as little time as it takes to charge the battery.

The Battery Charging Process
1. Charge only batteries that are cool to the touch and are not damaged. Look at the battery to make sure it is not damaged e.g., swollen, bent, broken or
punctured.
2. Attachtheinputcordofthechargertotheappropriatepowersupply(12Vaccessoryoutlet).

notgobelow3Vpercell.
Installing a Receiver
Battery Selection and Installation
1. Install your park flyer or full range receiver in the fuselage using hook and
loop tape or double-sided servo tape.
2. Attach the elevator, aileron, flap and rudder servo connectors to appropriate
channels of the receiver.
3.AttachtheESCconnectortothethrottlechannelofthereceiver.
1.WerecommendtheParkZone1300mAh11.1VLi-Pobattery(PKZ1033).
2.Ifusinganotherbattery,thebatterymustbeatleasta1300mAhbattery.
3.Your battery should be approximately the same capacity, dimensions and
weight as the ParkZone Li-Po battery to fit in the fuselage without changing
the center of gravity a large amount.
Turn the clevis clockwise or counterclockwise on the connector. Make sure
transmitter trims are centered before making this adjustment.

the rudder and fuselage. The black and red decal will be facing up with
the black orientation stripes facing down. Make sure horizontal tail is
centered on the fuselage.
2. Apply 4 pieces of tape to horizontal tail sections and top and bottom of
fuselage.

CAUTION: Always remove the flight battery from the aircraft when you
are done flying, or when you are on the way to the flying field.
Flying
Always choose a wide-open space for flying your ParkZone Radian Pro. It is
ideal for you to fly at a sanctioned flying field. If you are not flying at an ap-
proved site, always avoid flying near houses, trees, wires and buildings. You
should also avoid flying in areas where there are many people, such as busy
parks, schoolyards, or soccer fields. Consult local laws and ordinances before
choosing a location to fly your aircraft. For more information about sailplane
flying, thermals and slope lift, refer to www.horizonhobby.com.
Flaps
The flaps on the Radian Pro are primarily used for
glide path control. The flaps allow for more drag and
additional lift to allow the plane to fly slower and
descendatasteeperrate.Withtheapslowered,
the Radian Pro can land in much smaller areas than
would be able otherwise. The flaps cause the Ra-
dian Pro to pitch up if deployed at higher speeds. If
using a transmitter without elevator/flap mixing it is ad-
visable to deploy the flaps at lower airspeeds to prevent the pitch up when
theapsarelowered.Withtheapsdeected,aileroneffectivenessisslightly
reduced.
Repairs
