If you ever crash your 9Eagle Cessna RC plane, it’s a great idea to have some spare parts on hand. Crash kits are bundles of factory parts for RC aircraft that are sold at a discount. With the 9Eagle Crash kit you can restore your 9Eagle Cessna electric RC plane to like new condition. Foam parts and propellers can break easily, so it’s a good idea to get the crash-kit ahead of time so that you have them on hand when you need them. The parts included with this crash-kit are:
A Spare Propeller
The spare propeller is exactly the same as the original. It presses securely onto the motor protector (a small clip on the front of the motor shaft) and is friction fit. Install the new propeller by:
- Remove the broken propeller by gently pulling back on it near the motor shaft. Be careful not to cut yourself on the broken motor, which may be very sharp. Grab it with a paper towel or rag if you can’t handle it safely.
- Slide the new propeller onto the motor protector and press until it clicks.
A Spare Wing
The spare wing is identical to the original, and comes with the same fastening system. Install it by sliding the clear plastic tab (referred to as “pins” in the manual) to the front of the airplane and bolting the end to the fuselage with the included screw.
Spare Vertical and Horizontal Stabilizers
The vertical and horizontal stabilizers go on the tail. Part of the vertical stabilizer is a rudder that moves left and right; and part of the vertical stabilizer is the elevator which moves up and down. The procedures for replacing these parts are:
- Broken Vertical Stabilizer
- Take a sharp hobby knife or straight edged razor blade and cut along the root of the vertical stabilizer, about 1/8” into the foam. Don’t cut any deeper than this, or you risk damaging the tail and its internal parts. Be sure to cut completely around the part.
- Pull up on the vertical stabilizer, being careful to cleanly separate it from the tail and not cause rips or creases.
- Apply foam safe CA glue to the root of the new vertical stabilizer and press it into the track left by the old one. Sight down the front of the airplane and ensure that the new stabilizer is installed straight (not bent to the left or right).
- Broken Horizontal Stabilizer
- Follow the same steps above to remove the vertical stabilizer even if only the horizontal stabilizer is damaged. You will need both a vertical and a horizontal stabilizer to replace the horizontal stabilizer, as removing the horizontal stabilizer requires the removal of the vertical stabilizer.
- Score around the damaged horizontal stabilizer with your hobby knife or razor blade and remove it. Clean out the slot and the depression in the tail where the new horizontal stabilizer will be seated.
- Apply foam safe CA glue to the slot and depression where the new stabilizer will sit and press it into place. Sight down the length of the airplane and ensure that the new horizontal stabilizer is straight. Most CA glues will give you a few seconds to make final adjustments before they begin to cure.
- Follow step 3 in the last procedure to replace the vertical stabilizer.
Spare Battery
If the original battery becomes damaged in a crash (very, very unlikely), you should place it on a non-flammable surface and observe it for a few hours. If no visible signs of swelling or deformation occur then it should be safe to use again. If you notice any swelling or puffing then you should immediately place the damaged battery in a bucket of salt water and leave it there for several days. After this time, dispose of the old battery in the household trash (it is now safe to do so, and contains no toxic chemicals). Use the new battery exactly as you used the old one.
