Post-Flight Inspections and Maintenance
Ball Links
Make sure the plastic ball link holds the control ball, but is not tight (binding) on the ball. When a link is too loose on the ball, it can separate from the ball
during flight and cause a crash. Replace worn ball links before they fail.
Cleaning
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush or a dry lint free cloth.
Bearings Replace bearings when they become notchy (sticky in places when turning) or draggy.
Wiring
Make sure wiring is away from the helicopter frame edges and any moving parts. Replace damaged wiring and loose connections.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over tighten metal screws in plastic parts. Tighten screw so parts are mated
together, then turn screw only 1/8th of a turn more.
Rotors
Make sure there is no damage to rotor blades and other parts which move at high speed. Damage to these parts includes cracks, burrs, chips or scratches.
Replace damaged parts before flying.
Flight Guidelines and Warnings
• Always keep aircraft in sight and under control.
• Always keep people and pets at least 40 feet (13 meters) away when the
battery is connected.
• Always turn on throttle hold [TH HLD] if the blades strike anything.
• Always use fullly charged batteries.
• Always keep transmitter powered on when the battery is connected.
• Always keep moving parts clean.
• Always avoid flying in inclement weather such as rain.
• Always let parts cool after use before touching.
• Always remove batteries after use and before disassembly.
• Always have a first aid kit and appropriate fire extinguisher with you.
• Never operate aircraft with damaged wiring.
• Never touch moving parts.
WARNING:
Always use Horizon approved carbon fiber Main Rotor Blades with the Blade 500 3D to avoid injury and/or property damage.
After every flight
❏
Check all screws to make sure that they are still tight.
❏
Check to make sure no wire connections have begun to loosen.
After every 5 flights
❏
Check all screws to make sure that they are still tight using the
proper tools.
❏
Check to make sure no wires are chaffing.
After every 20 flights
❏
Check bearings to make sure they are still smooth.
❏
Check gyro tape and ESC tape to make sure they are still good.
❏
Check dampers and ensure they are not too soft, replace if necessary.
❏
Check belt tension, adjust if necessary.
After every 50 flights
❏
Check links and ensure that they do not pop off the balls too easy, replace
if necessary.
❏
Inspect belt and ensure it is not fraying and that no teeth are missing.
Maintenance check list
Adjusting the Drive Belt Tension
Belt tension that is too tight results in loss of power and causes the belt to
wear more quickly. Tension that is too loose can cause belt damage and loss of
tail rotor control in flight.
To check for proper belt tension:
1. View the tail rotor drive belt through the opening at the top of the tail case.
2. Use a hex wrench or standard screwdriver to compress the belt through the
opening.
3. Apply light pressure on the belt, compressing the belt toward the bottom of
the tail boom.
4. The belt tension is correct if the compressed side of the belt reaches
approximately halfway to the opposite side of the belt.
a. If the compressed side of the belt reaches farther than halfway to
the other side of the belt, the tension is too loose.
b. If the compressed side of the belt does not reach halfway to the
other side of the belt, the tension is too tight.
To adjust the belt tension:
1. Loosen the two horizontal stabilizer screws.
2. Loosen the six screws at the back of the main frame.
3. Slide the boom forward or aft to adjust the belt tension.
4. When the belt tension is properly adjusted, tighten the six screws at the
back of the frame.
5. Tighten the horizontal stabilizer screws.
Low Voltage Cutoff (LVC)
Low voltage cutoff (LVC) protects the Li-Po battery from overdischarge in flight
and activates when the battery reaches 3V per cell under load.
Set your transmitter timer for 4 minutes and land when the timer expires.
Repeatedly activating LVC damages the flight battery and you will need to
replace the battery.
Crash damage and battery damage are not covered under warranty.
