GYRO-STABILIZED 3CH WIRELESS INDOOR HELICOPTER PROPELLER SYSTEM
Your Gyro-Stabilized 3CH Wireless Indoor Helicopter propeller system is a precision instrument that
may need repair or replacement from time to time for optimal flight function. Crash landing from
high-speed aerial flights may cause damage to your Gyro-Stabilized 3CH Wireless Indoor Helicopter
propeller or propeller connecting rods.
TROUBLESHOOTING:
If your Gyro-Stabilized 3CH Wireless Indoor Helicopter loses its ability to fly correctly, please inspect
the propeller system carefully for the following two common issues:
1. Replacing Connecting Rod: The connecting rod is a small “handcuff” style device that stabilizes the
“upper” propellers. There are two connecting rods on the upper propeller. Please see (Diagram 1).
If a connecting rod is broken or missing simply replace it by “peeling” off the existing broken unit and
replacing it with a new one. You may have to use slight pressure when reattaching both ends of the
new connecting rod. Make sure that the new connecting rod is secured and locked in place. See
(Diagram 2). For changing connecting rod, make sure there is no damage to the actual blade or arm
that holds the connecting rod in place. If there is you must replace the entire blade system.
2. Replacing Upper and Bottom Propeller: The propeller is subject to damage as you learn to properly
fly and control your Gyro-Stabilized 3CH Wireless Indoor Helicopter. If after a crash your helicopter
has loss of control or flies erratically you should carefully inspect your entire propeller system for any
sign of damage. Most common are: cracked or chipped blade, broken “connecting rod”, frozen
balance bar (this is when the balancing bar and blade are jammed and can not move freely up and
down). To replace the propeller blades follow diagrams 3 through 12.

When you tighten the screw you should test the
blade to make sure that it still has free
movement. If the blade cannot move freely,
slightly loosen the screw.
