Replacing Propellers

Ensure rotation direction is correct. Always replace propellers with a set intended to rotate in the same direction (clockwise or counter-clockwise). We suggest replacing one propeller assembly at a time to minimize potential for mix-ups, rather than removing all propellers at once.
Always replace both propeller blades as a set. They are a matched and balanced pair, with matching serial numbers. This is to reduce vibration.
Remove fasteners between the prop hub and the motors: (x4) M3x10 bolts.
Remove the old propeller assembly.
Fit the new propeller assembly.
Apply Loctite 243 or equivalent to all screws before installing. torque to 1.5 Newton meters.
Reinstall (x4) M3x8 bolts.
Propellers are labelled with their orientation, Clockwise (CW) or Counter-clockwise (CCW).
The correct direction of the propellers is shown below. Please note the arrow indicating the front of the Astro, which is easily identified by the cylindrical antenna.

SIM Card

Access the SIM card by removing the SIM Panel fastener.

Fastener Specifications

Use Of Thread locker
Bolts and screws used in the daily use of this aircraft do not require threadlocking compound. This includes the screws securing the vibration isolation system and the landing gear parts.
However, for the structural fasteners described in parts of this section, blue Loctite 243 compound or equivalent is required. Apply sparingly to the threads before insertion.
Fastener Installation
The Freefly hex drivers included with Astro are designed to limit the torque that can be applied to each bolt or screw and help prevent stripping the fastener head.
Thread all fasteners into their respective holes until snug (when the fastener head bottoms out and lightly clamps the two mating parts together).
To prevent excessive tightening and damaging the fastener or parts, twist the driver from the smaller diameter knurled section of the tool between your thumb and index finger for small fasteners (under size M3) or with your thumb and two forefingers for larger fasteners (size M3 and larger).
