Landing

Find a suitable flying site

Perform the range check for your plane

Monitor your flight time

Find a flying site clear of buildings, trees, power lines and 

other obstructions. Until you know how much area will be 

required and have mastered flying your plane in confined 

spaces, choose a site which is at least the size of two to three 

football fields - a flying field specifically for R/C planes is best. 

Never fly near people - especially children, who can wander 

unpredictably.

As a precaution, an operational ground range test should be

performed before the first flight each time you go out. 

Performing a range test is a good way to detect problems 

that could cause loss of control such as low batteries, defective

or damaged radio components, or radio interference. This 

usually requires an assistant and should be done at the actual

flying site you will be using.

First turn on the transmitter, then install a fully-charged battery 

into the fuselage. Connect the battery and install the hatch.

Remember, use care not to bump the throttle stick. Otherwise,

the propeller/fan will turn and possibly cause damage or injury.

Note: Please refer to your Transmitter Manual that came with 

your radio control system to perform a ground range check. If 

the controls are not working correctly or if anything seems 

wrong, do not fly the model until you correct the problem. Make

certain all the servo wires are securely connected to the 

receiver and the transmitter batteries have a good connection.

Monitor and limit your flight time using a timer (such as on a 

wristwatch or in your transmitter if available). When the 

batteries are getting low you will usually notice a performance

drop before the ESC cuts off motor power, so when the plane 

starts flying slower you should land. Often (but not always) 

power can be briefly restored after the motor cuts off by 

holding the throttle stick all the way down for a few seconds.

To avoid an unexpected dead-stick landing on your first flight,

set your timer to a conservative 4 minutes. When your alarm 

sounds you should land right away.

Before flying the model 

Flying course

While applying power, slowly steer to keep the model straight.

The model should accelerate quickly. As the model gains flight

speed you will want to climb at a steady and even rate. It will 

climb out at a nice angle of attack (AOA).

Flying

Always choose a wide-open space for flying your plane. It is

ideal for you to fly at a sanctioned flying field. If you are not 

flying at an 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, schoolyards, or soccer fields. Consult laws and 

ordinances before choosing a location to fly your aircraft. After 

takeoff, gain some altitude. Climb to a safe height before trying 

technical manoeuvres, including high speed passes, inverted 

flight, loops, and point rolls.

Land the model when you hear the motor pulsing (LVC) or if 

you notice a reduction in power. If using a transmitter with a 

timer, set the timer so you have enough flight time to make 

several landing approaches.

The model’s three point landing gear allows the model to land 

on hard surfaces.  Align model directly into the wind and fly 

down to the ground. Fly the airplane down to the ground using 

1/4-1/3 throttle to keep enough energy for proper flare. Before 

the model touches down, always fully decrease the throttle to 

avoid damaging the propeller or other components. The key to 

a great landing is to manage the power and elevator all the 

way to the ground and set down lightly on the main landing 

gear. After a few flights you will find the model can be set down

lightlyon the mains and you can hold the nose wheel off 

balancing themodel on the mains until it slows and gently 

settles the nose.

Repairs to the foam should be made with foam safe adhesives 

such as hot glue, foam safe CA, and 5min epoxy. When parts 

are not repairable, see the Spare Parts List for ordering by item 

number.

Always check to make sure all screws on the aircraft are 

tightened. Pay special attention to make sure the spinner is 

firmly in place before every flight.
