SJM180(215)-C/F PRO Reference Assembly 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 [not used on the SJM180(215)]: 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 SJM180(215) as it will attract and collect dirt and debris and potentially cause hardware failure.
