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ight.
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 Cuto (LVC)
Lowvoltagecutoff(LVC)protectstheLi-Pobatteryfromoverdischargeinight
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ightbatteryandyouwillneedto
replace the battery.
Crash damage and battery damage are not covered under warranty.
