Great Planes Dazzler 40 Kit - GPMA0480 - Manual (Page 20)

Takeoff: If you have dual rates on your transmitter, set the
switches to “high rate” for takeoff, especially when taking off
in a crosswind. Although this model has excellent low
speed characteristics, you should always build up as much
speed as your runway will permit before lifting off, as this
will give you a safety margin in case of a “flame-out.” When
you first advance the throttle, the plane will start to turn left
(a characteristic of all “taildraggers”). Be ready for this, and
correct by applying sufficient right rudder to hold it straight
down the runway. The left-turning tendency will diminish as
soon as the tail is up and the plane picks up speed. Be
sure to allow the tail to come up. Don’t hold the tail on the
ground with too much up elevator, as the plane will become
airborne prematurely and possibly stall. When the plane
has sufficient flying speed, lift off by smoothly applying up
elevator (don’t “jerk” it off to a steep climb!), and climb out
gradually.
Flying: We recommend that you take it easy with your
Dazzler for the first several flights, gradually “getting
acquainted” with this responsive sport plane as your engine
gets fully broken-in. Add and practice one maneuver at a
time, learning how she behaves in each. For ultra-smooth
flying and most normal maneuvers, we recommend using
the “low rate” settings as listed on page 17. “High rates”
should be used for tearing up the sky, low level loops,
snaps and spins, and most quick response flying.
CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If, while
f l y i n g , yo u n o t i c e a ny u nu s u a l s o u n d s, s u c h a s 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 Dazzler. 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 Dazzler and have a blast
wowing the guys at the field.
