Great Planes Giant U-Can-Do 3D - GPMA1271 - Manual (Page 22)

4. I will operate my model using only radio control frequencies
currently allowed by the Federal Communications Commission.
❏
1. Fuelproof all areas exposed to fuel or exhaust
residue such as the wing saddle area, etc.
❏
2. Check the C.G. according to the measurements
provided in the manual.
❏
3. Be certain the battery and receiver are securely
mounted in the fuse. Simply stuffing them into place
with foam rubber is not sufficient.
❏
4. 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.
❏
5. Balance your model laterally as explained in
the instructions.
❏
6. Use thread-locking compound to secure critical
fasteners such as the set screws that hold the wheel
axles to the screws that hold the carburetor arm (if
applicable), screw-lock pushrod connectors, etc.
❏
7. Add a drop of oil to the axles so the wheels will
turn freely.
❏
8. Make sure all hinges are securely glued in place.
❏
9. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, cowl mounting
screws, etc.).
❏
10. Confirm that all controls operate in the correct direction
and the throws are set up according to the manual.
❏
11. Make sure there are silicone retainers on all the
clevises and that all servo arms are secured to the
servos with the screws included with your radio.
❏
12. Secure connections between servo wires and
Y-connectors or servo extensions and the connection
between your battery pack and the on/off switch with
vinyl tape, heat-shrink tubing or special clips suitable
for that purpose.
❏
13. Make sure any servo extension cords you may have
used do not interfere with other systems (servo arms,
pushrods, etc.).
❏
14. Secure the pressure tap (if used) to the muffler with
high temp RTV silicone, thread-locking compound or
J.B. Weld.
❏
15. Make sure the fuel lines are connected and are
not kinked.
❏
16. Balance your propeller (and spare propellers).
❏
17. Tighten the propeller nut and spinner.
❏
18. Place your name, address, AMA number and
telephone number on or inside your model.
❏
19. Cycle your receiver battery pack (if necessary) and
make sure it is fully charged.
❏
20. If you wish to photograph your model, do so before
your first flight.
❏
21. Range check your radio when you get to the flying field.
The Giant U-CAN-DO 3D ARF is a great-flying model that
flies smoothly and predictably. The Giant U-CAN-DO 3D
ARF does not, however, possess the self-recovery
characteristics of a primary R/C trainer and should be flown
only by experienced R/C pilots.
Whether you are looking to practice new 3D maneuvers and
don’t want to risk your competition aircraft, or are just
starting to learn the most basic aerobatics, the Giant U-CAN-
DO 3D ARF is a great choice. Regardless of your skill level,
be sure your first flight begins with low rates (yes, even in a
crosswind) and that you gradually expand your flight
envelope, adding one new maneuver at a time.
Take offs, landings and most of your normal flights should
be flown on low rates. (If your radio does not have dual
rates, be sure to set the model up on the low rates
provided.) The high rates on this model are meant ONLY
for use when doing 3D aerobatics – maneuvers
performed while the model is flying slower than its
normal stall speed. That includes maneuvers as simple as
a stall turn, or as complex as harrier rolls.
Don’t get spoiled by how incredibly well the Giant U-CAN-
DO 3D ARF hangs and torque rolls! Most models take an
enormous amount of work to keep the model stationary in a
hanger, but the unique design of Giant U-CAN-DO 3D ARF
helps lock it solid in position and torque roll and hang with
relative ease.
This is a high-performance 3D aerobatic aircraft. It is not
designed for, and cannot withstand, high speeds. Please
know that we have tested this model VERY extensively, with
literally over 100 flights across numerous test models with a
huge range of power plants.
FOR YOUR SAFETY AND THE SAFETY OF YOUR
MODEL, PLEASE:
1. DO NOT exceed the engine recommendations of 1.60
cu in [26.0cc] glow or 2.5 cu in [41.0cc] gas.
2. DO NOT exceed the maximum pitch for your propeller of
8" (i.e. 18x6 not 16x10).
3. DO NOT fly the model at full throttle, except on climbs of
at least 10 degrees (no straight and level and no wide
open dives).
4. DO NOT allow the model’s tail surfaces to be hit,
pushed, pressed upon or otherwise damaged during
handling or during extreme flight maneuvers.
A fully cowled engine may run at a higher temperature than
an un-cowled engine. For this reason, the fuel mixture
