how she behaves in each. For ultra-smooth flying and most
normal maneuvers, we recommend using the “low rate”
settings as listed on page 19. “High rates” should be used for
tearing up the sky, low level loops, snaps and spins, and most
quick response flying. Speed is the key to good knife-edge
performance.
CAUTION
(THIS APPLIES TO
ALL
R/C AIRPLANES): 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 airplane, any time you detect flutter
you must
immediately
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 are slop-free. If it fluttered once, it
probably will flutter again under similar circumstances
unless you can eliminate the slop or flexing in the linkages.
Here are some things which can result in flutter: excessive
hinge gap; not mounting control horns solidly; sloppy fit
of clevis pin in horn; elasticity 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 make your final approach into the wind. For your first
landings, plan to land slightly faster than stall speed and on
all three wheels, as this is the easiest way to land your Uproar.
Later, with a little technique, you will find you can make slow
landings on just the main gear, with the tail flyin’ high.
We hope you enjoy your Uproar and have a blast wowing the
guys at the field.
