Pre Flight Checks:
1. As a precautionary avoidance to frequency interference (two different helicopters utilizing the same frequency), it is important to keep the remote
controllers and helicopters apart for at least a distance of 0.5 miles. In order to prevent accidental encounters from occurring; please make sure the
surrounding areas (the flight area) are not populated with crowds and/or buildings (look for open space). Any open space vicinity should be at least 100 feet
in all directions.
2. Make sure the battery is completely charged. Read carefully the suggested charging time and maintenance procedures listed in the instruction manual.
Attempted flight without a fully charged battery will result in an unexpected loss of power, directional control, and/or costly accidental crashes. Remember,
by NOT discharging the battery completely during usage, you will maintain its efficiency and increase its life span.
3. You are now ready to turn ON both the transmitter (remote control) and the receiver (located on the helicopter). Make sure the helicopter is placed on a
flat leveled surface on the ground before commencing. Always turn on the transmitter (remote control) FIRST before turning on the receiver.
4. Test and confirm the directional controls are working properly. Try moving the directional stick and study the resulting effects of the helicopter. If no
resulting movement is noticed when moving the directional stick, do not attempt flight as either the helicopter or the remote control may be defective.
5. Before any test flight, it is recommended to tie the helicopter to a fixed restraint mechanism under safe conditions and then gradually increase its power;
making sure the helicopter can perform various movements until at least one battery is depleted in order to confirm all parts fit properly. When finished,
carefully check the entire helicopter over to see if there are any loose parts and/or screws and make adjustments as needed.
The following guidelines list the most recommended methods for a beginner to commence their journeys into the remote control flying realm (listed in the
order of importance):
1. Find an experienced Instructor – most likely can be found at your local hobby store.
2. Join a RC club in your nearby area – can be found through the internet, hobby stores, parks, and friends (word of mouth).
3. Make sure you are standing directly behind the helicopter before any attempted flight.
4. Slowly introduce power to the helicopter in a continuous and stable pace.
5. Analyze carefully the characteristics of the helicopter. As more power is introduced, the helicopter will begin its ascension progress. Make directional
adjustments to counter and insure a linear ascending or descending path.
6. Make sure never to exceed a flying height of over 3 feet! Anything over the recommended height can and may cause major damage to the helicopter
if crashed.

7. Upon reaching the recommended maximum height, slowly release and let off on the throttle till landing. Always maintain the helicopter’s plane level
to the ground.
8. Continually practice this technique until you can masterfully perform linear ascending and descending paths, as well as stationary hovering
capabilities.
9. As your skills improve, slowly introduce lateral movements to the helicopter; with your starting point of spot as the final goal (position). Make sure to
keep the lateral distances within a 3 feet diameter. Furthering the recommended distance will increase accidental encounters.
10. Once these techniques are mastered, you are now ready to elevate both your helicopter and flying skills to its potential.
11. It’s strongly recommended for softened landings, slightly tilt and allow the front part of the landing strut to touch down, followed by the rear half.
Notes:
The majority of crashes experienced by beginners are associated with behaviors of nervousness and/or panic. Only a small percentage is directly related to
mechanical failures. Repetitive practice is the only way to enhance your skills such as developing controls sensitivity, awareness, and understanding. Regular
maintenance is required to keep the SJM430 helicopter in optimal and safe flying condition. This helicopter requires precise configuration of the components
and settings to be kept by the owner. Conduct regular maintenance on the SJM430 to avoid accidents or loss, and to ensure optimal performance.
Main Rotor Checklist:
1. Main rotor housing: When the main rotor housing is worn or faulty, there will be obvious vibration and poor flight control. Check the main rotor, main
shaft, and feathering shaft for wear or deformity. Replace parts as necessary to eliminate imbalance.
2. O-rings (not used on the SJM430): The O-rings will lose their elasticity over time. This will cause excess play on rotor and cause instability. Replace
as needed.
3. Main rotor hub: If the helicopter will not fly or begins to reacts sluggishly, even after checking for proper setting of pitch and throttle, check the
following items:
•Blade grip Bearings
•Swing arm/control arm bearings
•Rotor blades
•Other relevant moving parts
4. Check for excess play or gaps between the surfaces, missing or broken parts, or binding restricting free movement. It is very important to check for
main rotor balance before each flight. Operating the helicopter “out of balance” will cause excessive wear and premature failure of parts, possibly
resulting in a dangerous situation.

SJM430-C PRO/E² Reference Manual
5. Control arm assembly: Check regularly for cracked, worn, bent or binding control arms and pushrods. Smooth movement of control arms and
linkages is required for stable, vibration free flight.
6. Swash-plate: Check for excess slop in the main ball that the main shaft rides on and slop or looseness among all the metal parts. Swash-plate wear
will result in poor stability and lack of control during flight. Replace as necessary.
Fuselage/Chassis:
1. Main shaft bearing: The normal replacement interval for proper operation is between 60-100 flights. If performing 3D or other extreme aerobatics,
inspect the bearing more frequently and shorten the interval as necessary.
2. One-way bearing: One-way bearings have longer lifetimes and failure is not common. To keep the one-way bearing in good operation, remove it to
clean and lubricate after every 50 flights. If the main drive gear is loose, you should replace the one-way bearing.
3. Drive belt: SJMRC/RC-TEK uses only top quality, stretch-resistant belts. It is however, impossible to prevent the belt from stretching or wearing out.
Check belt tension regularly, and check for the wear on the teeth. Replace as necessary.
Linkage Rods and Connecting Parts:
During assembly, take special care to keep the connecting parts in smooth operation, and avoid excess play or binding. Failure to do so will result in poor
flight stability. The linkage rods and ends will break and wear due to normal usage, crashing, and poor maintenance. Check for wear and proper operation
regularly and replace as needed.
Tail Rotor System:
1. Tail rotor control set: Check the tail rotor bearing regularly. If there is excess play or gaps, replace immediately. Avoid any binding or improper
contact on the tail components and bearings as this will cause excessive wear and heat, potentially melting and/or deforming the tail system.
2. Tail unit assembly: Avoid flying in tall grass or weeds. If grass or weeds become lodged in the tail rotor unit, it may interfere with the operation, and
cause the helicopter to lose control. Always check for foreign objects in the tail and clean them off immediately. Avoid using lubricants on the
exposed surfaces of the SJM430 as it will attract and collect dirt and debris and potentially cause hardware failure.

3. Tail rotor housing: Disassemble the tail rotor housing for cleaning and maintenance after every 50 flights. If the tail does not operate smoothly or
exhibits any signs of stress or wear, it should be replaced immediately.
4. Tail rotor: Check the tail rotor blades regularly for damage, especially if the helicopter ever strikes the ground while flying or after any hard landings.
Damaged tail blades can induce vibration.
Closing Reminder:
Maintaining and taking care of your SJM430 on a regular basis will result in the helicopter providing you with safe and enjoyable flying experiences for years
to come.
