labeling for both 30 & 50 respectively.

Every attempt has been made to ease the assembly of your kit, at each step where there are complex

instructions there are detailed written instructions to walk you through each step. Remember to take a

few minutes before each step to carefully examine each step to become familar with the parts and assem-

The tools and materials listed below are

the minimum needed to build the helicopter:

In addition, the following will make assembly and setup

easier, and prove useful later in your model toolbox:

Remove oil

residue from

fasteners before applying

any threadlock agent.

Tap holes with

machine screws

before installing steel

balls in plastic.

Tap holes with

machine screws

before installing self tap

screws in plastic.

Tap holes with

machine screws

carefully in plastic holes

with bottoms.

Fuel 15-30% Helicopter fuel is recommended

containing more oil. Use a fuel filter between

the fuel gallon and the heli to remove any dirt

that could stall the engine. Fuel the helicopter

by removing the fuel line from the carburator

and replace when finished.

Needle Valve Following the engine manufactur-

ers instructions, turn the main needle valve until

closed and open to the setting the instructions

call for. Different engines will have different

settings.

Radio Always turn the transmitter on first,

then the helicopter & gyro and reverse when

finished, turn off the heli & gyro first then the

transmitter. If the radio acts erratically or

intermittent, find the problem before starting

the engine.

Glow Plugs Using a glow plug connector, re-

move the canopy or optionally use a remote glow

plug connector to heat the glow plug. Warning!!

glow plugs operate at 1.5V **not 12V.**

Engine Before starting the engine, check the

correct direction of rotation and make sure the

electric starter is turning the same direction.

Starting Start the engine from low throttle with the

trim centered. Holding the rotor head in one hand,

angle the starter and press down slightly to engage the

starting shaft into the fan. Start the electric starter

until the engine starts. If the engine does not start

recheck all previous points. The main blades will not

turn until the engine RPM is above idle.

Stopping To stop the engine, with the throttle stick

in the low position, move the trim all the way to the

low position.

Starting Your Engine

First Flights For the beginner pilot, a training pod is strongly recommended to assist in learining to

hover the helicopter with substantially reduced risk of crashing. These systems provide an on ground

training capability to allow pilots to become familiar with the helicopter before actually leaving the ground.

Pitch In steps 41-44 you setup the pitch range using

a pitch gauge and setting the pushrods on the servo

horns at specific distances. Once the helicopter is

flying the pitch setting have to be fine tuned. Using

appropriate training gear, increase the throttle until just

before the helicopter lifts off and sight the rotor disk

from 15' back. If there appears to be 2 rotor disks then

adjust Pushrod C until only one disk appears. Using

colored tape mark one blade so you can adjust the

correct blade.

Adjusting the Blade Tracking

Q. The engine does not turn easily with the starter.

A. The starter battery may be too weak or the engine

is flooded. For flooding, remove the glow plug and

turn the engine over several times to clear the com-

bustion chamber of fuel and retry.

Q. The engine rotates and tries to start but doesn't.

A. The glow plug may be getting old. The glow plug

batteries are weak. The starter may be turning the

wrong direction.

If the Engine Does Not Start

Q. The engine just does not start.

A. The glow plug may be burned out. Fuel may not

be getting to the engine, check for a clogged fuel line,

dirt in the carburator or the main needle needs to be

opened out slightly.

Q. The engine starts but immediately stops.

A. There is a clog in the fuel line, the carburator is not

open enough at idle- open the throttle trim by 1-2

clicks. Helicopter engines have a low speed needle

which is factury set, beginners should not adjust it!!

Before each flight, check that all bolts and screws are tight. Simply flying your helicopter, will loosen any

screws which are not threadlocked or secured with a lock nut.
