4) I will operate my model using only radio control frequencies
currently allowed by the Federal Communications Commission.
5) I will not knowingly operate my model within three
miles of any pre-existing flying site except in
accordance with the frequency sharing agreement
listed (in the complete AMA Safety Code).
9) Under no circumstances may a pilot or other person
touch a powered model in flight; nor should any part of the
model other than the landing gear, intentionally touch
the ground, except while landing.
CHECK LIST
❍
1. Check the C.G. according to the measurements
provided in the manual.
❍
2. Be certain the battery and receiver are securely
mounted. Simply stuffing them into place with foam
rubber is not sufficient.
❍
3. Extend your receiver antenna and make sure it has
a strain relief inside the fuselage to keep tension off
the solder joint inside the receiver.
❍
4. Balance your model
laterally
as explained in the
instructions.
❍
5. Use thread locking compound to secure critical
fasteners such as the set screws that hold the
wheel collars to the landing gear, screws that hold
the carburetor arm (if applicable), the screw-lock
pushrod connector on the throttle servo, etc.
❍
6. Add a drop of oil to the axles so the wheels will
turn freely.
❍
7. Make sure all hinges are securely glued in place.
❍
8. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, hatch covers,
main landing gear screws).
❍
9. Confirm that all controls operate in the correct
direction and the throws are set up according to
the manual.
❍
10. Make sure all the servo arms are mounted to the
servos with the screws included with your radio.
❍
11. Make sure none of the servo wires orY-connectors can
get caught in any of the pushrods or servo arms.
❍
12. Make sure the fuel lines are connected and are
not kinked.
❍
13. Balance your propeller (and spare propellers).
❍
14. Tighten the propeller nut and spinner.
❍
15. Place your name, address, AMA number and
telephone number on or inside your model.
❍
16. Cycle your receiver battery pack (if necessary) and
make sure it is fully charged.
❍
17. If you wish to photograph your model, do so before
your first flight.
❍
18. Range check your radio when you get to the flying field.
FLYING
The Tower Hobbies Uproar 40 ARF is a great-flying model
that flies smoothly and predictably.The Uproar 40 ARF does
not, however, possess the self-recovery characteristics of a
primary R/C trainer and should be flown only by pilots who
have some R/C experience.
Before the first flight of the day don’t forget to do a range
check with the engine off and with the engine running. Also
don’t forget to check to make sure all the controls respond
in the correct direction before EVERY flight.
Before takeoff, see how the Uproar 40 ARF handles on the
ground and check to see if the tail wheel is straight. Do not use
the rudder trim to get the model to roll straight. Instead, use
pliers to carefully bend the tail gear wire as necessary. When
ready for takeoff, point the model down the runway into the wind.
Gently apply full throttle to keep the model from“looping out” on
the ground. When adequate speed has been reached gently
apply up elevator to lift the model into the air. After reaching a
safe altitude fly around for a few minutes to see how the Uproar
40 ARF behaves in different situations. Adjust the trims as
necessary to get the model to fly straight-and-level. If you find
the Uproar 40 ARF a bit of a handful you can always throttle
back to make it fly and react slower.While still at a safe altitude
make a few practice landing approaches by cutting the throttle
CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If,
while flying, you notice an alarming or unusual sound
such as a low-pitched “buzz,” this may indicate control
surface
flutter
. Flutter occurs when a control surface
(such as an aileron or elevator) or a flying surface (such
as a wing or stab) rapidly vibrates up and down (thus
causing the noise). In extreme cases, if not detected
immediately, flutter can actually cause the control surface
to detach or the flying surface to fail, thus causing loss of
control followed by an impending crash.The best thing to
do when flutter is detected is to slow the model
immediately by reducing power, then land as soon as
safely possible. Identify which surface fluttered (so the
problem may be resolved) by checking all the servo
grommets for deterioration or signs of vibration. Make
certain all pushrod linkages are secure and free of play.
If it fluttered once, under similar circumstances it will
probably flutter again unless the problem is fixed. Some
things which can cause flutter are; Excessive hinge gap;
Not mounting control horns solidly; Poor fit of clevis pin in
horn; Side-play of wire pushrods caused by large bends;
Excessive free play in servo gears; Insecure servo
mounting;and one of the most prevalent causes of flutter;
Flying an over-powered model at excessive speeds.
During the last few moments of preparation your mind
may be elsewhere anticipating the excitement of the first
flight.Because of this, you may be more likely to overlook
certain checks and procedures that should be performed
before the model is flown. To help avoid this, a check list
is provided to make sure these important areas are not
overlooked. Many are covered in the instruction manual,
so where appropriate, refer to the manual for complete
instructions. Be sure to check the items off as they are
completed (that’s why it’s called a
check list!
).
