Shown here is a HomeFlite plans built
cockpit with a unique DIY Yoke and throttle. The build came
about from a purchase of parts from a damaged CH Yoke from
ebay. The case had been damaged so the case and throttle lever knobs were missing. Everything else seemed to be there.
The purchase from ebay totaled $30.00
This article is quick look at how a
resurrected CH Yoke received a new body and performs just as
well as the original. It is actually better with the separate
This was a very cheap construction project
using the electronics of the original unit. Wood scraps and
pieces from around the shop were used with a couple of other
cheap parts to keep construction costs to a minimum.
A photo of the basic components and the
completed housing. The housing was constructed of plywood and
various pieces of wood stock to support various components in
the housing. Shell size and mounting supports were copied from
the shell of another working yoke. The cable is the usb
connector that goes to the PC board for the unit.
The construction generally followed the
size of the original shell to make mount fabrication and
measurements easier. The original shell has all mounting molded
in. It was fairly easy to create an alternative mounting system
using wood scraps A separate mounting compartment was fabricated
for the two levers. Their location is further out from the yoke
Parts ready for trial fit. No matter how
simple it looks adjustments will need to be made. The shell is
The general layout and testing of the
parts fit are shown above.
After testing had to make the spring
mounts stronger . Also adjusting the pot for the correct throw
movement was very delicate. The ears on the yoke column had to
be shortened as it was hitting the springs on both sides.
A thin piece of metal sheeting is used on
the top of the shell. The top is the limit stops for how far the
yoke can be turned from side to side since it will collide with
springs if nothing is there to limit travel.
The compartment for the switches is added.
The throttle housing was constructed in
much the same manner as the yoke housing. Scrap MDF board and
some wooden dowels make up the housing, throttle. prop and
The original throttle quadrant pc board
and pots were used making the height of enclosure higher for
clearance. Sliding pots could have been used but the original
worked fine at no extra cost. I actually used the plastic handle
off of a bag of cheap foam paint brushes to attach to the pots.
The levers were then attach to the dowels with metal collars.
Foam cushioning was used for the dowels
and adjusting the screws varies the tension on each slide.
Wooden cabinet knobs were obtained from a local hardware store
and then painted. I used some cat5 cable and a 9 pin connector
to plug into the yoke housing to connect the throttle quadrant
board to the main board.
The units have rubber feet on the
bottom and the heavy construction of the throttle enclosure
stops it from sliding around. I used an extra clamp from a
Saitek throttle quadrant and mounted it on the yoke, it fit
