AMA SAFETY CODE
Read and abide by the following Academy of Model
Aeronautics Official Safety Code:
GENERAL
1. I will not fly my model aircraft in competition or in the
presence of spectators until it has been proven to be airworthy
by having been previously successfully flight tested.
2. I will not fly my model aircraft higher than approxi-
mately 400 feet within 3 miles of an airport without notifying
the airport operator. I will give right of way to, and avoid
flying in the proximity of full scale aircraft. Where necessary
an observer shall be utilized to supervise flying to avoid
having models fly in the proximity of full scale aircraft
3. Where established, I will abide by the safety rules for the
flying site I use, and I will not willfully and deliberately fly
my models in a careless, reckless and/or dangerous manner.
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 the ULTRA SPORT 60
has great 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". If you have built a tricycle gear configuration and the
ground handling seems too quick and "squirrely," this can be
easily fixed by reducing the amount of nose gear steering
throw.
FLYING: We recommend that you take it easy with your
ULTRA SPORT 60 for the first several nights and gradually
' 'get acquainted'' with this fantastic ship as your engine gets
fully broken-in. Add and practice one maneuver at a time,
learning how she behaves in each one. For ultra-smooth
flying and normal maneuvers, we recommend using the * * low
rate" settings as listed on page 35. "High rate" elevator and
rudder may be required for crisp snap rolls and spins. "Low
rate" rudder is best for knife edge. If you notice any
'' sluggishness " in the way your ULTRA SPORT 60 handles,
it is probably a result of not enough speed, in which case you
should install a propeller with increased pitch. Do not exceed
the recommended "high rate" throws for the rudder, as this
will only result in pitch-down when full rudder is applied.
Speed is the key to good knife-edge performance.
RADIO CONTROL
1. I will have completed a successful radio equipment
ground check before the first flight of a new or repaired
model.
2. I will not fly my model aircraft in the presence of
spectators until I become a qualified flyer, unless assisted by
an experienced helper.
3. I will perform my initial turn after takeoff away from the
pit, spectator and parking areas, and I will not thereafter
perform maneuvers, flights of any sort or landing approaches
over a pit, spectator or parking area.
FLYING
The ULTRA SPORT 60 is a great Hying sport airplane
that flies smoothly and predictably, yet is highly maneuver-
able. It does not have the self-recovery characteristics of a
primary trainer, therefore you must either have mastered the
basics of R/C flying or seek the assistance of a competent
R/C pilot to help you with your first flights.
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 flut-
ter 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 will probably
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; Exces-
sive "play" or "backlash" in servo gears; and Inse-
cure servo mounting.
LANDING: When it's time to land, make your approach low
and shallow, as this ship wants to just keep on flying (espe-
cially if built light). If you find that it lands a little fast, you
might try dialing in a few clicks of up elevator when you cut
