Pre - Flight

• All the control surfaces should have about 15-20mm of movement

in each direction.

• Check the center of gravity with installed payload placement

• Check all control surface functions again for correct movement and

do a range test.

• Check all functions before each flight. 

• Start the UAV with full throttle and hand launch slightly upwards.

• Trim the UAV so that it flies straight and make necessary adjustments

as required to correct for any undesirable characteristics noted during

the initial flight.

Note: MAJA operates only within temperature range of – 5 to +50 ° C.

We point out expressly that we do not have influence on the assembly and the flight 

operation of the MAJA and we will not be held liable for damages which result from

the building or from the flying operation.

Safety Guidance Information

Please observe the following safety notes.

If the UAV is passed on to another person, these safety notes and the building instruction should be pass on for 

compliance. For safety reasons, only use the original kit components and accessories.

As manufacturers, BORMATEC are not in a position to influence the way you build and operate your model, and we have no

control over the methods you use to install, operate and maintain the radio control system components. For this reason we are

obliged to deny all liability for loss, damage or costs which are incurred due to the incompetent or in correct use and 

operation of our products, or which are connected with such operation in any way. Unless otherwise prescribed by binding law, 

the obligation of the BORMATEC Company to pay compensation, regardless of the legal argument employed, is l limited to the

invoice value of that quantity of BORMATEC products which was immediately and directly involved in the event in which the

damage occurred. This does not apply if BORMATEC is found to be subject to unlimited liability according t o binding legal

regulation on account of deliberate or gross negligence.

Be sure to read right through the instructions covering assembly and operation of your model before you attempt to operate it. 

You alone are responsible for the safe operation of your radio-controlled UAV. Young people should only be permitted to

build and fly this UAV under the instructions and supervision of an adult who is aware of the hazards involved in this activity.

These building instructions must be kept in a safe place. If you ever dispose of the UAV be sure to pass them on to the new

owner.

Radio-controlled aircraft are very demanding and potentially dangerous machines, and call for a high level of technical

knowledge and skill from the operator, together with a responsible attitude.

In legal terms our UAVs are classed as aircraft, and as such are subject to statutory regulations and restrictions which must be

observed. The brochure “Modellflugrecht” (Law and the Model Flyer) contains a summary of all these rules. There are also

government regulations concerning your radio control system, and these must be observed at all times. Refer to your RC

system instructions for more details. Be sure to use only those parts included in the kit, together with other genuine

BORMATEC accessories and replacement parts as recommended expressly by us. Even if you change a single component you

can no longer be sure that the system will work reliably, and such changes also invalidate your guarantee.

It is important to use matching polarized connectors exclusively. All high-current cables, connectors and flight batteries must be

insulated carefully to avoid short-circuits, especially if you assemble them yourself. Never combine connectors made of different 

materials, e.g. tinplated and gold-contact types, as they may not work reliably.

The high energy density of rechargeable batteries involves a permanent danger of fire and even explosion. Follow the 

precautions outlined in battery usage.

A radio-controlled aircraft can only work properly and fulfill your expectations if it is built very carefully and in accordance with the

building instructions. If you wish to avoid injuring people and damaging property it is essential to be careful and painstaking at

all stages of building and operating your UAV. Nobody would c limb into a full-size sailplane and try to fly it without

completing a course of training first. UAV flying is just such a skill, and has to be learned in just the same way.

General Information

However, as manufacturers we have no means of influencing the way you build and operate your RC model aircraft, and for this 

reason we can do no more than point out the hazards expressly. We accept no further liability. If you need help, please enlist

the aid of an experienced hobby craft flyer, join a flying club or enroll at a hobby craft flying training school. Hobby shops and

the hobby aircraft specialist are also good sources of information. The best course is always to join a club and fly at the

approved flying site.

Adhesives contain solvents which may be hazardous to health under certain circumstances. Read and observe the notes and

warnings supplied by the manufacturers of these materials. The operator of the aircraft must be in full possession of his bodily 

and mental faculties. As with car driving, operating a hobby aircraft under the influence of alcohol or drugs is highly dangerous 

and not permissible under any circumstances.

Make sure that all passers-by and onlookers are aware of the hazards involved in the operation of your model. Remind them to 

keep a safe distance from the model: at least 5 m behind the plane of the propeller. Keep a safe distance between your model 

and other people or objects. Never fly low over people or directly towards them. Radio-controlled aircraft should only be flown in 

“normal” weather conditions, i.e. a temperature range of -5° to +35° C. More extreme temperatures can lead to changes in 

battery capacity, material characteristics, the strength of glued joints and other unwanted effects. All hobby flyers should behave 

in such a way that the danger to people and property is minimized. Never act in any way which will disturb other pilots, or 

prevent safe, orderly flying at the site.

Don’t operate your UAV in the vicinity of overhead power cables, industrial sites, residential areas, public roads, squares , 

school playgrounds, public parks or sports fields etc.

Pre-flight checks. Before every flight be sure to carry out a range check, and ensure that all functions are working correctly.

This is the procedure: switch on the transmitter, followed by the receiver. Leave the transmitter aerial collapsed, and walk

away from the UAV. At a reasonable ground range check that all the control surfaces still work perfectly when you move the 
BORMATEC, Mooswiesen 17/2, D-88214 Ravensburg 8

sticks. Repeat the check with the motor running, while someone holds the mod el securely.

The first time you fly any new model aircraft we strongly recommend that you enlist the help of an experienced modeler to help

you check the model, and offer advice while you are flying.

Don’t ignore our warnings. They refer to hazardous materials and processes which, if ignored, can result in fatal injury or serious 

damage to property. Propellers and other rotating parts which are powered by a motor represent a permanent hazard and

present a real risk of injury. Don’t touch them with any part of your body.

For example, a propeller spinning at high speed can easily cut your finger quite badly.

Keep well clear of the rotational plane of the propeller. You never know when some part may come loose and fly off at high 

speed, hitting you or anybody else in the vicinity. Never touch the revolving propeller with any object. Ensure that there is no 

chance of any object obstructing the propeller and preventing it turning.

Take care with loose clothing such as scarves, loose shirts etc. Flapping cloth can easily be sucked into the area of the propeller 

and then get tangled in the blades. This is extremely dangerous.

If you start your motor when the model is standing on loose or sandy ground, the propeller will suck up sand and dust and hurl it

around, and it could easily get in your eyes and do damage. Wear protective goggles at such times.

Safety Information for Flying UAV

Every time you intend flying the model, check carefully that all parts connected to it are working correctly, including prope llers, 

gearboxes, RC components, etc. Everything must be properly located and firmly secured. Check for possible damage, and do 

not fly your model unless you are confident that everything is in perfect order. Whenever you are holding the aircraft make sure 

that you are standing on a safe surface and cannot slip. Wear shoes with high-grip soles, such as trainers.

Do not switch on an electric motor unless you are sure that there is nothing in the rotational plane of the propeller. Don’t attempt to

stop the spinning propeller with your hands. Never run an electric motor with a propeller fitted unless it is firmly anchored. If you

are to fly your aircraft safely and avoid problems it is essential that you are aware of its position and attitude throughout each flight

- so don’t let it fly out of line of sight! If you detect a control problem or interference during a flight, immediately land the aircraft

to prevent a potential accidents. UAVs must always give way to full-size aircraft. Take-off and landing strips should be kept free

of people and other obstacles. Your RC system can only work reliably if the batteries are kept fully charged. Never use batteries 

which are hot (over 50oC), faulty or damaged. Heed the instructions provided by the battery manufacturer at all times. Before 

every flight be sure to carry out a range check, and ensure that all functions are working correctly.

Note in particular that the motor control function on the transmitter must first be set to the OFF pos ition before you switch on the 

system. Always switch on the transmitter first, then the receiving system. When switching off, reverse the order: receiving 

system first, then the transmitter. Check that the control surfaces work in the correct “sense”, i.e. they move in the direction 

which corresponds to the stick movement. After each session remove all the batteries from the model and store them in a 

discharged state at a temperature of about +5° to +25° C. They should be kept out of the reach of children at all times.

Please don’t misunderstand the purpose of these notes. We only want to make you aware of the many dangers and hazards

which can arise if you lack knowledge and experience, or work carelessly or irresponsibly.

ATTENTION

In some countries it is a legal requirement to carry third party indemnity 

insurance when operating a radio controlled model. Please ask your local

dealer, governing body or your insurance company for details.
