In order
to install a trim tab, a section of the trailing edge of the RH
elevator was removed and provisions made to accept the trim tab
and it's piano hinge.
|
|
|
|
A trim tab was constructed of
urethane foam and glass cloth. An aluminum strip is embedded
within the trim tab, to provide a place to rivet the control horn
and hinge.
|
|
|
|
The trim tab is shown attached
to the elevator with the aluminum piano hinge. The control horn
isn't visible here, as it's located on the bottom of the trim tab
|
|
|
|
Here you see both the elevator
and rudder trim tabs installed in their respective locations. I
preferred to incorporate the tabs into the control surfaces,
rather than add them to the trailing edges.
|
|
|
|
To control the trim tabs, I
constructed a "vernier" type controller. It uses
"traveling blocks", moving along handwheel actuated SS
threaded rod, to actuate the SS "push-pull" wires, which
run in Bowden type cable housing. An engraved, black plastic
faceplate, with indicator marks, will be attached
|
|
|
|
The stock throttle levers were
replaced with some that I fabricated out of misc.
"stuff" I had on hand. The throttle knobs were turned
from Delrin rod, as was the knob on the kickstand control lever.

Other innovations on this site include a "Kickstand" for your
Challenger!
