Air System and Electronics (For Models shipped prior to September 2015)
The aircraft is fitted with high quality electronic air actuation valves. These valves are
controlled by the sequencer board shown. The sequencer features a digital display that
displays the air pressure (bar) in the system. A low pressure failsafe is set to extend the gear
if the pressure falls below 3 bar in flight. The
sequencer comes pre-programmed with
sequencing delay. See the
section titled “Landing
Gear/Door /Brake Sequencer Instructions
” if
adjustments are required. The set of two valves
are connected to the gear doors, open and closed.
The set of three are connected to the landing gear;
Brakes, gear Up, and gear Down. The brake valve
is non-proportional, either on or off. Use BVM
Super O-Lube on the main wheel brake drums to
prevent skidding. See the section titled
“Lubing the
Brakes
” for instructions.
Fill the Air system to 70 psi, or 4.8 bar before each
flight.
Helpful Tip:
Use a scrap piece of BVM Air Line
inserted into the fill valve; chamfer the end for
easy insertion.
