CAUTION (THIS APPLIES TO ALL R/C AIR-
PLANES): If, while flying, you notice any unusual
sounds, such as a low-pitched "buzz", this may be an
indication of control surface "flutter". Because
flutter can quickly destroy components of your air-
plane, any time you detect flutter you must immedi-
ately cut the throttle and land the airplane! Check all
servo grommets for deterioration (this will indicate
which surface fluttered), and make sure all pushrod
linkages arc slop-free. If it fluttered once, it will
probably flutter again under similar circumstances
unless you can eliminate the slop or flexing in the
linkages. Here are some tilings which can result in
flutter: Excessive hinge gap; Not mounting control
horns solidly; Sloppy fit of clevis pin in horn; Elas-
ticity present in flexible plastic pushrods; Side-play
of pushrod in guide tube caused by tight bends;
Sloppy fit of Z-bend in servo arm; Insufficient glue
used when gluing in the elevator joiner wire or
aileron torque rod; Excessive flexing of aileron,
caused by using too soft balsa aileron; Excessive
"play" or "backlash" in servo gears; and Insecure
servo mounting.

LANDING: When it's time to land, fly a normal
landing pattern and approach. You will find that the FUN-
ONE will slow up very well and land very nicely and
predictably. If your FUN-ONE is built straight and true,
you'll find that you can really flare it out for slow, nose-
high, full-stall landings without fear of tip stalling.
Have a ball! But always stay in control and fly in a
safe manner.
GOOD LUCK AND GREAT FLYING!
