GENERAL INFORMATION AND TECHNIQUES
CHASSIS
ALTA 8 ships from the factory with motors precisely aligned to minimize the
difference in motor speed between clockwise turning and counterclockwise turning
motors while in flight. Opening the chassis by removing the screws that attach either
the top or bottom chassis plates affects this alignment and may reduce ALTA 8
performance.
NOTE
Do not open the ALTA 8 chassis.
Opening the chassis affects factory alignment.
All maintenance items are outside the chassis and do not require the removal of
screws attaching the top or bottom chassis plates.
USE OF THREADLOCKER
Bolts and screws that are called out in this manual to regularly remove or replace
typically do not require use of a threadlock compound. This includes the screws
holding on the handle, battery retention strap studs, battery stops, closeout panels,
the top male Toad In The Hole adapter. In addition, fasteners that attach to nuts with
a nylon locking feature (nylock nuts) do not require threadlocker.
All structural fasteners require the use of threadlock. This includes chassis screws,
lower male Toad In The Hole adapter and motor attachment fasteners. In addition,
the four M3 x 8 socket head bolts that attach the folding propeller to the motor
require threadlocker. Typically, a low strength threadlocker (such as Loctite Purple
222) is used on structural fasteners.
BOLT INSTALLATION
The Freefly hex drivers included with ALTA 8 are designed to help limit the torque
that can be applied to each bolt.
Thread all fasteners into their respective holes until “snug”. This is when the
fastener head bottoms out and lightly clamps the two mating parts together
To prevent tightening the bolts excessively and damaging the bolts or parts, it is
suggested to hold the wrench in your hand, and twist the wrench 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).
