LET’S TALK GIANT SCALE
no excessive twist on the control surfaces,
it is time to begin the fine-tuning process.
For the plane to fly well, you must ensure
proper incidence angles for the wing(s) and
the horizontal stabilizer. All reputable kit
manufacturers state the proper incidence
angles for their models. If this is not the case,
it is important to seek advice. Typically, you will
begin with the incidence angle between your
wing and stabilizer so
that they are parallel to one another and
that the engine is also aligned. Then, take to
the skies to trim the model.
With a pure aerobat, you should be able to
perform a vertical dive in which the aircraft
tracks completely vertical. If it demonstrates
any pull or push, however, increase or decrease
both the wing or stab incidence angles. With a
Hold the trailing edge of a given control surface and apply small movements to
ensure that no undesired movement is exhibited. If any slop is present, isolate and
address the cause.
When a biplane

You can use a clevis for certain applications. Here, you see the aileron connector
rod attached to the top surface of the biplane’s bottom aileron.
