Old School Model Works Lark Construction Manual

Using the Manual
Be sure to read each step thoroughly before you start
the step. Test-fi t the parts together to make sure they
fi t properly. If necessary trim to fi t.
Beside each step you will notice a check box (or two).
These are so you can keep track of your progress
while building your kit. For steps that have two boxes,
as in the construction of the left and right wing halves,
these steps must be performed two times.
• Your Old School Model Works aircraft should not be
considered a toy, but rather a sophisticated, working
model that functions very much like a full-size airplane.
Because of its performance capabilities, this model, if not
assembled and operated correctly, could possibly cause
injury to yourself or spectators, and damage to property.
• You must assemble this model according to the
instructions. Do not alter or modify this model, as doing
so may result in an unsafe or un-fl yable model. In a few
cases the instructions may differ slightly from the photos.
In those instances the written instructions should be
considered as correct.
• You must take time to build straight, true and strong.
• You must use a R/C radio system that is in fi rst-
class condition, a correctly sized power system and
components (electronics,
throughout the building process.
• You must correctly install all R/C and other components
so that the model operates correctly on the ground
and in the air. (Installation shown in the manual is a
suggestion. You may have to adjust the mounting steps
to accommodate the size of your radio equipment.)
• You must check the operation of the model before every
fl ight to insure that all equipment is operating and that
the model has remained structurally sound. Be sure to
check clevises or other connectors often and replace
them if they show any signs of wear or fatigue.

• If you are not an experienced pilot or have not fl own this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your fi rst fl ights. If you're not a member of a club, your
local hobby shop has information about clubs in your
area whose membership includes experienced pilots.
• While this kit has been fl ight tested to exceed normal
use, if this model will be used for extremely high stress
fl ying, such as racing, or if a power system larger than
one in the recommended range is used, the modeler is
responsible for taking steps to reinforce the high stress
points and/or substituting hardware more suitable for the
increased stress.
Remember: Take your time and follow
the instructions to end up with a well-
built model that is straight and true.
