This channel is used to Manual Mode 900μs Futaba JR Spektrum AILERON ELEVATOR THROTTLE RUDDER CH5/GEAR Diagram HOTT

5 ESC Initial Setting Before install FC450, please finish the ESC initial setting. Make sure ESCs and FC450 have the same stroke setting.if you use Dualsky ESC, you can set all ESCs after FC450 installation by the following steps: Turn on the radio controller, push the throttle stick to the top, turn on power to the quadcopter, when L1 shows blue in color, it means the ESC is in initial setting mode; Wait until the ESC's long beep (it means the top point of throttle has been confirmed), then pull the throttle stick to lowest point; Wait about 1 second for a short beep (it means the lowest point of throttle has also been confirmed), the ESC initial setting is finished; Don't move the throttle stick after initial setting, turn the power off to the quadcopter, then reconnect the power after 5 seconds, the new setting will be applied. FC450 Setting How to enter Setting Mode: Turn on radio controller, move the throttle to lowest position; turn on power to the quadcopter, wait until the L1 LED finishes flashing Green and then changes to RED (Now the flight control is in Lock Mode); press the SET button on the flight control to enter Setting Mode. After you enter Setting Mode, L1 displays the corresponding SETTING ITEM menu attributes (color), and L2 displays the corresponding SETTING VALUE menu attribute (color). SET Button usage: 1) Long Press (more than 2 sec) under Lock Mode: enter Setting Mode 2) Single Click under Setting Mode: switch between SETTING ITEM 3) Double Click (finish within 0.5 sec) under Setting Mode: change SETTING VALUE 4) Long Press (more than 2 sec) under Setting Mode: Save and Quit to Lock Mode Please check the chart at the right side for all settings Some settings will take effect after the FC450 restarted. Cut the power to the quadcopter and reconnect after 5 seconds to apply the new settings.

6 Unlock & Propeller Direction Check Make sure your quadcopter's battery is fully charged, and you are in a wide and flat area; Turn on the radio, pull the throttle stick to lowest position, plug in the power to the quadcopter. L1 LED on FC450 Flight Control will flash Green (initial startup process), don't move sticks on the radio controller, keep the quadcopter still. When the L1 LED changes to Red, it means the initial startup process has finished and the quadcopter is now in Lock Mode (throttle will not operate). Move the sticks as shown in the diagram 7 and hold for about 0.5 sec to unlock the quadcopter. After unlock, motors will reach idle speed for about 1 sec. If you don't do any stick movements during this period after "unlock" (5-seconds) the quadcopter will return to Lock Mode again. After unlock, push the throttle a fraction above idle speed, check if the propellers run in correct direction like shown in below diagram. Ground Test Set all sensitivity potentiometers on FC450 to neutral. CH5 is used to adjust flight mode, if you are using it, please toggle the CH5 switch before flight, L2 LED will indicate the state of the current switch position: blue indicates low stick input, green indicates high stick input. Put the CH5 switch to low(auto level flight mode). Low L2 Blue (0.5S) High L2 Green (0.5S) Diagram

7 Direction check: Controlling the throttle, make sure the quadcopter doesn't leave the ground. Slightly move each stick to observe if the quadcopter moves with your stick input direction. If the direction is opposite, please change the channel direction on the radio. Low altitude Test Flight After unlock, control throttle to make the quadcopter maintain a 0.5 meter altitude. Observe if the quadcopter is stable. If it s not stable, you need to adjust the sensitivity of the FC450. The channel center point can differ depending on the choice of radio brand, the installation of FC450 can also cause deviation. If the quadcopter has deviation after take off, please adjust the trim on radio to find the center position. Adjust the sensitivity 450 class quadcopter can use the default setting to get a good flight performance. The weight on the quadcopter can differ depending on the choice of battery. This will impact center of gravity, and the flight characteristics. To improve flight performance you can address the below. Normally, if the sensitivity is set too high on the pitch (elevator) axis, the opposing axis (i.e., aileron) will vibrate; if the sensitivity is set too low on the pitch (elevator) axis, the opposing axis (i.e., aileron) will respond with delay to stick movement. If the sensitivity is set too high on the rudder axis it will cause the motors to over react, which will make the quadcopter unstable in pitch and yaw direction; if the sensitivity is set too low on the rudder axis, the quadcopter will have difficulty on tail lock. When adjusting the sensitivity, don t change the setting value too much, 5-10 degrees a time is enough. When you find a stable range, then tweak it for optimum performance Caution Please don t pull throttle to the lowest position during flight, it might cause the motor suddenly be stopped and crash the quadcopter. When you fly in high maneuvering condition for a long time, the external acceleration will cause the FC450 to not be able to maintain a horizontal status. This is normal. After hovering the quadcopter for few seconds, FC450 will adjust the quadcopter to complete horizontal
