❏ 1. Fuelproof all areas exposed to fuel or exhaust
residue such as the cowl ring, cowl mounting
blocks, 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 threadlocking compound to secure critical
fasteners such as the set screws that hold the wheel
collars, struts, 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 securely 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 Little Toni is a great-flying model that flies smoothly and
predictably. The Little Toni does not, however, possess the
self-recovery characteristics of a primary R/C trainer and
should be flown only by experienced R/C pilots.
Fuel Mixture Adjustments
A fully cowled engine may run at a higher temperature than
an un-cowled engine. For this reason, the fuel mixture
should be richened so the engine runs at about 200 rpm
below peak speed. By running the engine slightly rich, you
will help prevent dead-stick landings caused by overheating.
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.
FLYING
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 checklist 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.
