9.) Helicopter Radios
On helicopter radios that have revolution mixing, either inhibit the function or set the revolution mixing amounts to 0 (zero) percentage. Also
remove any rudder offsets, or tail curves if available on the radio. The Hummingboard is designed to automatically add tail rotor into the main rotor
to compensate for increased torque as the throttle is advanced.
10.) The First Flight
Turn the transmitter on first. While making the battery connection, ensure that the rotor blades will not touch yourself or anything on the work
surface. After the battery is connected, wait for 5 seconds for the control board and gyro to initialize, the red LED on the gyro will stop blinking.
If the throttle stick in not at the lowest position, the LED will remain solid red. The LED must change to green to start the motors. While firmly
holding the landing skids, slowly lift the throttle stick to turn the main blades slowly, stopping at half stick (50% power). If the blades do not turn
and the LED is red, lower the throttle stick, disconnect the battery and change the position of the Servo Reversing function for the throttle channel
on the radio. Repeat the procedure. If the LED blinks from red to green there is no signal from the radio.
11.) Common Questions & Answers
Q: Everything is on and connected why don't the rotors turn? A: The throttle trim may be set too high try moving the trim to the lowest point.
Your gyro may be installed incorrectly make sure the the order of wires is as shown in steps 5 and 9. Also your throttle channel may be reversed.
Q:Why does the Helicopter spin like a top? A: It's possible that the rudder channel on your radio is reversed or your gyro is installed upside
down. please see step 2 for best mounting location. Again check the connections to the receiver to make sure connections are correct. If the
problem persists take a look at the direction the tail motor turns. the curved portion of the tail rotor should move forward being the "leading edge"
if this is not the case please check the polarity of the motor's connection to the mixer board.
Q: Why is there vibration? A: The main blades may be out of track. Check out step 15 on the next page. The main shaft may be bent. This can be
difficult to notice when the blades are not moving. a bent main shaft can be caused in a crash or a hard blade strike. Vibration can also result from
any loosely connected components such as the battery tray or the landing gear. Make sure to secure them using the provided mini rubber stoppers
and be sure to check the frame and flybar every time you crash or have a hard landing.
Q: Why won't the helicopter come off of the ground? A: be sure that the gear mesh on the main motor moves smoothly and that the battery is
fully charged. Do not fully discharge a NiMH type battery as it will lose it's capacity memory. If you don't think it's the battery it's possible
that the centrifugal force created by the spinning blades has flattened out the curve in the rotor blades. Carefully bend the plastic back in to a curve
trying to keep the curve of both blades as equal as possible.
During regular operation the Hummingboard will remain solid green but as the battery starts to run out and the voltage drops the helicopter will simply
descend. At this time it is best to land immediately.
IMPORTANT NOTES:
-JR radio equipment. On JR radios, the throttle channel needs to be reversed. -
When using radio equipment that is different than shown in the manual, you will
need to reposition the receiver and the Hummingboard to make all the connec-
tions. - HummingBoard. It is normal on some radios to have the LED on the board
solid green at below half stick then change to solid red from half stick to full
power. This is normal operation. - JR receivers: The connectors on the
HummingBoard are square in design, when using an original JR receiver, two
edges need to be shaved (chamfered) to fit into the receiver.
13.) Transmitter Adjustments
All flight trimming adjustments should be done on a flat, hard surface in a minimum area of 20 feet by 20 feet to ensure that trimming can be
completed. All helicopter trimming is always observed from the pilot home position. Position the Hummingbird 6 feet ahead of your position
with the nose forward. When observing reactions from the helicopter, always think in terms of which direction the nose moves. Never be
concerned with the tail, and never watch the tail. It is recommended to use optional training gear, #CNE053 before trying to trim or fly the
model.
Rudder Setup - Turn the transmitter on. Insert your hand and hold the landing gear firmly while making the battery connection, ensuring
that the main and tail rotor blades will not touch yourself or anything on the testing surface. Move the helicopter to the testing position, 6
feet in front of yourself. Slowly raise the throttle until the main blades are slowly turning. Carefully add right rudder on the transmitter, and
observe that the nose of the helicopter turns to the right. If the helicopter turns to the left, reverse the rudder channel on the transmitter.
Gyro Setup - Gyro gain is preset. Insert your hand and hold the landing gear firmly while making the battery connection, ensuring that the
main and tail rotor blades will not touch yourself or anything on the testing surface. Wait 5 seconds after power on to initialize the gyro
(blinking green LED goes solid), do not move the helicopter during this time. Verify that when the rudder stick is moved to the right the nose
rotates to the right, the throttle stick may need to be raised slightly to activate the electric motors. Holding the tail boom at the back of the
frame from below jerk the nose to the left, the tail rotor should start rotating moving the nose right. This may take a few tries to verify gyro is
in the correct direction. If the helicopter is powered up with the gyro reversed, the helicopter will spin uncontrollably. To reverse the gyro
direction, reinstall the gyro upside down. Repeat the gyro setup test. (more on next page)
12.) Antenna Mounting
The last important wire to route is the antenna, it is vital that
the antenna wire is isolated from all the other wires and motors
on the helicopter. Install the antenna along the bottom of the
frame, making sure it does not touch another wire and that it
does not cross itself. Run the end of the antenna out to the
horizontal fin, attaching it with a small elastic or piece of tape.
