Check that motor spins are one CW and the other is CCW and that you are using one prop CW and the other CCW. Power Pack C Twin comes with:
(2) HQ Propellers 10 x 4.5 CCW
(2) HQ Propellers 10 x 4.5 CW
The reverse spin prop is usually designated with an R after the size and pitch. e.g. 10 x 4.5 R
Lastly, try calibrating the ESCs individually. Remove Y harness and connect 1 ESC, calibrate, then repeat for other. Here are the full ESC instructions.
FT ESC Normal startup procedures
Move throttle stick to the bottom position and then switch on transmitter→ Connect battery pack to ESC→ The long “beep” sound should be emitted , means the bottom point of throttle range has been detected→ Several “beep” tones should be emitted to present the amount of battery cells→ When self-test is finished, a “♪ 1 2 3” tune should be emitted→ Move throttle stick upwards to go flying.
Throttle range setting procedures (when users change a transmitter, throttle range setting is recommended.)
Switch on the transmitter, move throttle stick to the top position→ Connect battery pack to ESC→ Two “beep” sounds should be emitted, means the top point of throttle range has been confirmed and saved→ Move throttle stick to the bottom position (within 2s), a long “beep” sound should be emitted , means the bottom point of throttle range has been detected→ Several “beep” tones should be emitted to present the amount of battery cells→ When self-test is finished, a “♪ 1 2 3” tune should be emitted, Move throttle stick upwards to go flying.
If the throttle stick is neither at the bottom position nor the top position after powered on, it will constantly make “beep” sounds.
Programmable parameters
1. Brake Type: There are six brake types including OFF, Low, Mid-low, Middle, Mid-high and High. The default is OFF.
2. Timing Mode: There are five options: Low: 0°, Mid-low: 8°, Middle:15°, Mid-high:23° and High:30°. The default is Middle: 15°. Low advance timing is recommended for high inductance and low KV motors. High advance timing is recommended for low inductance and high KV outrunner motors. For some high KV motors, if it shakes while rotating in high speed, the High timing mode is recommended.
3. Start Force: There are 13 options: 0.03、0.05、0.06、0.09、0.13、0.19、0.25、0.38、0.50、0.75、1.00、1.25、1.50. The default is 0.75. Select the corresponding start force according to the load of motor.
4. Reserved for new programmable parameters.
5. Control Frequency : 2 options: 8KHz and 22KHz. The default is 8KHz. This option is the drive frequency of the motors.
6. Low-voltage Protection: 4 options: 2.8V/cell、3.0V/cell、3.2V/cell、Off the low voltage protection . The default is 3.0V/cell. the system will automatically identify the battery cell. E.g. suppose there’re 3 cells, if the voltage is lower than 9V, the system will work according to the current cutoff option
Programming via Transmitter
Step 1: Enter program mode
Switch the transmitter on→Pull the throttle stick to the top position→Switch the ESC on, wait 2 seconds, you will hear two “beep” sounds, which
denotes that Max. throttle has been confirmed→Hold the throttle stick at the top position, and then wait 2 seconds until you hear tune “♪ 1 2 3
3”, that means you have entered the transmitter programming mode.
Step 2: Select program parameters
Hold the throttle stick on top position, there’re 7 parameters can be set by using your transmitter. You would hear 7 different indicating sounds which correspond to 7 different parameters. Pull the throttle stick to the bottom position (full Off throttle) within 2 seconds after you hear the correspondent sound will brings you to the correspondent parameter setting status. The indicating sounds will repeat in turn as follow.
1. “beep-” (a short sound) which indicates the Brake Type
2. “beep-beep-” (two short sounds) which indicates the Timing Mode
3. “beep-beep-beep-” (three short sounds) which indicates the Start Force
4. “beep-beep-beep-beep-” (four short sounds) -------------------
5. “beep-----” (a long sound) which indicates the Control Frequency
6. “beep-----beep-” (a long sound and a short) which indicates the Low-voltage Protection
7. “beep-----beep-beep-” (a long sound and two short) which indicates the Cutoff Mode
Step 3: Select program values
After entering parameter setting status, hold the throttle stick on the bottom position, you will be led to the repeat selection of that parameter setting status. Each sound likes 4 short sounds and one long sound (1 long sound=5short sounds), and by that analogy. After some sound, pull the throttle stick to the top position in 2 seconds, after you hear a tune “♪3 2 1 ♪3 2 1”, which means the correspondent value has been chosen and saved. Hold the stick on the top position, return to the second step and continue programming.
Step 4: Exit program
Pull the throttle stick to the bottom position within 2 seconds and hold on after saving parameters, until you hear a tune “beep----
1 2 3”. Set the Min. Throttle at this moment and exit program and operate as normal.(beep----means Loading parameter. beep- beep- beep-means numbers of cells and ♪1 2 3 means ready. )
Restore Factory settings
To restore Factory settings, pull the throttle stick to the bottom position (full Off throttle ) within 1s after entering program mode (Step 1)→Pull the throttle stick to the top position within 2s, then you will hear a tune, which means that the factory settings have been restored. Pull the throttle stick to the bottom position within 2s, the ESC is ready with factory settings.
