Step 3

Attaching the Wing

In order to attach the wing of your Radian, please follow 

these simple instructions:

1. Locate the wing spar, as well as the left and right 

wing panels.

2. Slide the wing spar into the socket located in either 

the left or right wing panel. Confirm the wing spar 

is fully seated in the socket.

Note:

 Use caution when inserting the wing spar into 

the sockets of the left and right wing panels. Pushing 

too hard will damage the wing panels.

3. Slide the wing spar and panel through the opening 

in the fuselage.  Slide the wing panel into the 

fuselage, making sure it is fully seated.

4. Slide the opposite wing panel onto the wing spar. 

Press the remaining wing panel into the fuselage 

until it is fully seated.  The wing panels are keyed 

to “lock” when the wing is installed.

Step 2

Charging the Flight Battery

The Radian comes with a 12V 2-3 cell DC balancing 

charger and 3S 11.1V 1300mAh Li-Po battery. You 

must charge the included Li-Po battery pack with a Li-Po 

specific charger only (such as the included charger). 

Never leave the battery and charger unattended during 

the charge process. Failure to follow the instructions 

properly could result in a fire. When charging, make 

certain the battery is on a heat-resistant surface.

DC Li-Po Balancing Charger Features

• Charges 2- and 3-cell Lithium Polymer  

battery packs

• Automatically detects incorrect cell count selection

• Simple single push-button operation

• LED charge status indicator

• LED cell balance indicator

• Audible beeper indicates power and charge status

• 12V accessory outlet input cord

Specifications

• Input power: 12V DC, 2A

• Charges 2- to 3-cell Li-Po packs with minimum 

capacity of 300mA

• Variable charge rates from 300mAh to 2 amps

3S 11.1V 1300mAh Li-Po Battery Pack

The ParkZone 3S Li-Po battery pack features a 

balancing lead that allows you to more safely charge 

your battery pack when used with the included 

ParkZone Li-Po balancing charger.

To Complete the Charging Process

1. Attach the input cord of the charger to the 

appropriate power supply (12V accessory outlet), 

or use the HBZ6513 (optional) and attach to 12V 

AC power supply. Once your charger has been 

correctly powered up, there will be an approximate 

3-second delay and then you will hear an audible 

“beep” and the green (ready) LED will flash.

2. Refer to the chart below to select the appropriate 

charge rates:

Note: 

When charging the included 1300mAh battery, 

set the charge rate dial to 1.3A or lower. Selecting 

a charge rate higher than 1x battery capacity may 

cause a fire.

3. Select the proper number of cells that you will be 

charging, either 2 or 3 cells. In the case of the 

1300mAh battery included with the Radian, you will 

select 3 cells.

4. Locate the safety charge lead on the battery pack. 

The charge lead of a 3-cell Li-Po battery will plug 

into the larger 4-pin port on the bottom right of 

the charger. A 2-cell pack will need to plug into the 

3-pin port on the bottom left of the charger. Once 

the battery is properly plugged into the correct 

port, it will beep 3 times if it is a 3-cell, and twice if 

it is a 2-cell pack. Once this is done, you are ready 

to proceed to charge the battery pack.

5. Push the start button to begin the charging 

process. Once this is done, the charger will make 

an audible beep that matches the cell count, and 

then the red (charge) LED will begin to flash. Do  

not adjust the current once the charger has begun 

to charge.

Note: 

At times, the green LED may also flash during 

the charging process, indicating that the charger is 

balancing one or more of the cells at the same time  

it is charging the battery pack. When this is occurring, 

the red and green LEDs will both be flashing. It will 

not always be necessary for the cells to be balanced.

6. When the battery pack is fully charged, you will 

hear an audible beep for about 3 seconds, and the 

green LED will be solid. Always unplug the battery 

from the charger immediately upon completion. 

Failure to do so could cause a fire.
