ALTA X is designed to be as low-maintenance as possible. It is recommended to check ALTA X’s fasteners regularly. This check should occur roughly after every 15 flights. To check ALTA X’s fasteners, apply a tightening torque to each fastener on the chassis using the supplied hex drivers. The fasteners should not slip.
Check the tightness of the following fasteners to verify no loose fasteners:
- Motor mount bolts
- Boom clamping bolts
- Prop hub bolts
- Prop bolts
- Top and bottom chassis bolts
- Closeout panel bolts
- FPV camera mounting plate bolts
- Boom stay attachment bolts
- GPS/Compass mounting bolts
Check the tightness of the fasteners as described above.
Inspect the following items. Replace if worn.
- Propeller blades - Chips, cracks, or deep scratches
- ActiveBlade bumpers - Broken or crushed
- Frame Bumpers - Broken or crushed
- Pan Isolator Rings - Tearing or gummed up to the post
Check boom latching tightness by closing the latch. There should be a firm closing force and click. Adjust the tension by using a 2.0mm hex wrench on the set screw located in the rear of the latch link.
For long-term storage, it is recommended you put your batteries on a storage charge every 3 months. The batteries can over discharge over time due to parasitic loss in the BMS. Making sure your batteries are at proper storage voltage every three months will prevent permanent damage due to over-discharging.
The longevity and health of the battery is fully dependent on how you treat and care for it. One important aspect of the care of a lipo is storage voltage. Storing the battery at a charged voltage for more than 2-3 days will start to degrade the battery. The optimal storage voltage for lipos is 3.8v to 3.9v per cell (45.6v to 46.8v total.) After a mission, a Lipo charger can be used to put batteries in “Storage Mode”. This will either discharge or charge your battery to get it to storage voltage. Batteries should be placed in a cool environment with a recommended storage temperature from 10°C to 25°C. For storage make sure your battery is kept in a dry fireproof cabinet.
We recognize that our users put Freefly gear into a wide variety of demanding situations and count on their equipment to perform reliably. Freefly recommends that users send their equipment back on the following intervals for a checkup to ensure optimal long-term performance and reliability.
Freefly will inspect your Alta with specific emphasis on:
- Wear / fatigue items
- Updated / improved / revised components
- Confirm performance thresholds:
The service will include:
- Service bulletin and firmware updates.
- Full airworthiness inspection
- Full cleaning and fastener replacement (as needed)
- System level test and re-qualification
