Optional Flaps

The Bf-109G is equipped with servo pockets in the wing

for making the flaps operational. To make the flaps

functional you will need two additional servos (PKZ1081),

the flap pushrod set (PKZ4921), and a Y-harness

(PKZ1063).

1. Plug Y-harness into the flap or gear channel of the

receiver. Plug flap servos into the y harness. Power

on radio and move the flap switch to the up position.

Turn off radio and unplug airplane. (see image 2 for

servo arm orientation in the up position).

2. Place servos in flap pockets using hot glue, silicon

glue, or double-sided servo tape. Peel back the tape

covering the servo lead and run the flap servo leads

in the same channel. Re-secure the tape over the

servo leads.

3. With the ailerons in the neutral position attach

control horn so the holes in the horn are over the

hinge line. Use the aileron control horns for position

reference.

4. Attach pushrod to servo control horn and adjust

clevis so it attaches to the control horn on the outer

hole without pushing or pulling on the aileron.

5. Cut the aileron at the panel line on the aileron. Make

sure there is 1/16 inch gap between the aileron

and flap to prevent interference between the two

surfaces.

6. Power on the airplane and radio and make sure you

are getting even throw on both flaps.

Note: When the flaps are installed the aileron area is

much smaller than whenusing the full span ailerons.

The roll rate in flight will be reduced. The aileron throw

can be increased to compensate for the reduced

aileron area. See step 9 for control throw for the

ailerons with flaps installed.

Note: The flap servo pockets have been positioned so

it is possible to make the inboard flaps operational. This

will require the purchase of an additional flap linkage

set. The outline for the inner flap is on the top surface

of the wing. Hinging options are up to the modeler to

implement. Picture below shows placement of additional

control horn for inboard flaps.

Note: The recommended settings are set at the default

settings (see point #5, page 11).

30-Amp Pro Switch-Mode BEC Brushless

Controller

Your Bf-109G BNF comes out of the box with the E-flite

30-Amp Pro Switch-Mode BEC Brushless Controller. This

controller has been designed for use in radio control

aircraft and is designed to support motor currents up

to 30 amps continuous, and a 5-volt Switch-Mode BEC

circuit capable of 700mAh continuous current on any

recommended input voltage with a 3- to 4-cell Li-Po

battery. It is suitable to use with most radio brands.
If you intend to fly your Bf-109G BNF stock, then there

is no need to program your ESC. It comes installed with

the default settings. If you intend to re-program the ESC,

we strongly recommend removing the propeller first in

order to keep it from spinning if the motor is accidentally

engaged.

Note: ALWAYS assume the motor and the propeller

are live. ALWAYS keep clear of the propeller at all

times. The high rpm of the brushless motor can cause

severe injury.

Features

• Up to 30-amp continuous current with proper airflow,

35-amp peak

• 5-volt Switch-Mode BEC circuit capable of

700mAh continuous current on any recommended

input voltage

• Drives up to 5 analog or 4 digital sub-micro servos

with the BEC

• 3S-4S Li-Po or 9- to 12-cell Ni-MH/Ni-Cd input voltage

• Programmable motor braking

• Safe power-arm mode prevents accidental starts

• Programmable low voltage cut-off with settings for

3S Li-Po (9.2V), 4S Li-Po (12V) or 74% of battery

starting voltage

• Programmable soft start for helis and airplanes

• Auto motor shutdown if signal is lost or there is

interference

• Programmable timing - 5 user-selectable ranges for

use with a larger variety of brushless motors

• Heli mode for starting the motor with a low

speed ratio

• Optional RS232 Serial Link available for programming

(EFLARS232)

• Pre-wired connectors - E-flite EC3 connectors on

battery input and 3.5mm female gold bullets on

motor output leads

Using the 30-Amp Pro Switch-Mode BEC

Brushless Controller

This controller is very simple to use, and for safety, will

not arm the motor until the throttle stick has been held

in the Idle/Off position for more than 1 second. The

controller will indicate the soft cutoff voltage setting

every time you plug the battery in by first emitting a

low, long tone, to indicate startup. Depending on the

selected cutoff voltage (default is 74%), you will then

hear the respective number of medium length mid tones

to indicate the cell count or a musical tone for the 74%

cutoff, helping you to confirm the setting before every

flight. Proper air cooling is required during flights so

the ESC should be placed in an area where air flows over

the controller.

Connecting the ESC to the Motor

The three wires from the motor connect to the three

female gold bullet connectors on the ESC. The order of

connection to the motor is not important; any motor wire

can be plugged into any connector. If the motor runs

backwards, you can simply unplug and switch any two of

the motor wire plugs connected to the ESC.

Mounting the ESC

Choose a location that has good airflow and offers good

protection. Do not cover the side with the flat heat shield

with hook and loop or tape as this will greatly reduce its

effectiveness. Mount the ESC with a combination of hook

and loop, 2-sided foam tape and/or tie wraps.

Starting Your Power System

1. Turn on your transmitter and ensure the position of

the throttle stick is set to Idle/Off.

2. Plug the battery pack into the controller. You will

hear 1 low long tone to indicate startup, then the

respective number of medium-length mid tones to

indicate the cell count or a musical tone for the 74%

cutoff, followed by 3 rising tones to indicate the

controller is armed.
