Test assembling before painting
Trim Wheels 3x10mm MDF
All Labels are cut out of 3-5mm acrylic sheet. After
heating to about 110°C in a baking oven bended in the right shape . Upper
layer is designed in a photo program and printed on photo paper. Then
spray glued to the acrylic and all the edges painted. At last the label is
spray coated with mat varnish.
USB Axis- and Servo Card (Opencockpits) mounted on the TQ
Throttle handles connected to 100mm ALPS linear slide
potentiometers (10K ohm)
Throttle reverser is only working ON-OFF
The OC Relay Card on front of the TQ control the Trim
motor, Park Brake light and Speed Brake deploying (not working yet). May be
you can recognize an old BOSCH battery drill machine used as Trim motor. (a
little noisy). Throttle connected to computer 2009.
Back ground light (12V miniature bulbs)
New Trim Motor. After running Prosim (April 2014) the trim motor now also
work with MCP engaged. Therefore my old noisy trim motor (Bosch accu
drill) has been replaced by a small silent 12 V gearbox motor RB35 ratio
1:50 from Conrad Electronic
The speed brake auto deploy motor (lower) also a RB35 gearbox
motor ratio 1:200. When speed brake is armed and the plane touch down SIOC get a input from Prosim
and the relay card is activated. Motor run until lever is full up and
the motors stop.
The two upper gear motors (ratio 1:600) are for the auto throttle
movement but not finished yet.
Close up of the O-ring friction clutch. It protect the motor and
dose it possible to move the lever manual too. The movement is transferred
to the lever thru
a 3mm threaded rod .
Great update of Throttle Unit started up January
Nearly the whole unit has to be dismounted to get access
to the Throttle Levers. The old reverser ON/OFF switch
control is changed to potentiometers.
Just enough space for the only 4 mm thick slide
potentiometer (10 K ohm 30mm travel linear)
Mechanism for release the Spoiler Lever if not armed.
Parking Brake has also been updated with release solenoid.
The Toe Brakes must now be pressed before the Park Brake Lever can be set or
Throttle assembled again and connected to the DC Motor
Although I had tested the card and its self positioning function with god
result on a little test set up I got big problems to get it running on my
New parts for Throttle Lever Drives.
An extra gear wheel reduce speed of levers from 1,5 sec.
to 4 sec. ( idle to full). I use still an O-ring between gear wheel and
servo arm for friction but now it is possible to tune the skid torque to
I had to make a new frame for motors and gear. To
insulate motors from each others I have used 2 mm epoxy sheet.
Spoiler motor below and Throttle Lever motors on top.
With the new motor frame there was no longer space for
the Trim Wheel chain. I have moved the Trim motor and the Trim Wheels are now
driven by a rubber gear belt. This reduce the noise and load on the
gear motor under start and stop.
Attention! I have removed all the capacitors between motor connectors an
housing. They cause USB disconnection problems. It works also fine without
capacitors between motor connectors.
