Gear mechanisms en potmeters ready for assembly |
Gear mechanism for the throttle handles (ratio 1:3). The throttle-handles will
be placed on the large gearwheel, The small gearwheel is connected to the
potmeter (10kOhm, with max rotation of approx 300 degrees). The potmeters
will be connected to the A/D converters of the Opencockpits IOcard
controllers |
Trimmechanism including a servo to steer the trim indicator in the
housing (the 3 wires of the servo are visible. The trim wheel will be fixed
on a rotary encoder
|
Modular set-up of the mechanisms. On the right side additional space
for the trim mechanism |
knobs are made on a lathe. |
Throttle, prop and mixture knobs (made from round wood) |
Handles assembled (the trimindicator on the left is just for testing
purposes). The indicator used is on the picture below
|
Throttle, prop and mixture knobs (painted) |
Trim wheel indicator (the arc on the picture). On the arc the scale will be
glued. Indicator is driven by a servo and a gear. The indicator moves free
over the metal axis. On the axis the trim wheel will be assembled (fixed).
The metal axis is connected to a rotary encoder. |
25 pins connector assembled on the bottom of the throttle Q.
