Crash landing from high-speed aerial flights may damage your Air Combat rotor blades or connecting rods. TROUBLESHOOTING:
If your Air Combat loses its ability to fly correctly, inspect the propeller system carefully for the following two common issues:
1. Replacing The Connecting Rod: The connecting rod is a small handcuff style device that stabilizes the upper rotors. There is one connecting rod on the upper rotor. Please see Diagram 1. If a connecting rod is broken or missing simply replace it by removing 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. 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 The Upper and Bottom rotor blades: The rotor is subject to damage as you learn to properly fly and control your Air Combat. 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, and frozen balance bar (this is when the balancing bar and blade are jammed and can not move freely up and down). See diagrams 3 through 12. REPLACING CONNECTING RODS Diagram 1 There is one connecting rod on the upper rotor.
