Stand" or similar.
SUMMARY
While this may seem like a lot of "extra work" just
to make your airplane fly well, most of the things we have
listed here are just good common sense modeling proce-
dures If you use the above information as a guide to build
(or modify) your airplane, we are certain you will be very
well satisfied with the results.

MOTOR VIBRATION
If the propeller is slightly out of
balance, it may cause the rear of the
motor to vibrate against former F-l,
resulting in a noisy airplane. To pre-
vent this, cut a few narrow "wedges"
from balsa scrap and push them into
the gap between the motor and F-l, as
shown in the above drawing.
