Agricultural UAV ESC
FlyDragon Slim
1. The motor is not started while the power is on. And the alarm is beeping rapidly.
The throttle is not at the bottom position or the throttle range is too short.
2. The motor is not started while the power is on. And the alarm is beeping every one second
No receiver signal is detected. Please check the connection of receiver.
3. The motor is not started while the power is on. And the alarm is irregularly beeping
The throttle is at the maximum position or the throttle setting is reversed. Please check the throttle settings.
FlyDragon V3
1. The motor is not started while the power is on. And the alarm is beeping rapidly.
The throttle is not at the bottom position or the throttle range is too short.
2. The motor is not started while the power is on. And the alarm is beeping every one second
No receiver signal is detected. Please check the connection of receiver.
3. The motor is not started while the power is on. And the alarm beeps irregularly
The throttle is at the maximum position or the throttle setting is reversed. Please check the throttle settings.
4. Can the ESC support single cell voltage at 4.35V?(1S=4.35V)?
Yes, it can support 4.35V. Therefore 12S is 12Sx4.35V=52.2V。
FlyDragon V4
FPV Drone ESC
Raptor S-Tower
1. Does it support IBUS receivers?
Yes. Its wiring method is the same as SBUS. And you must choose IBUS in the receiver option of betaflight
2. The camera and VTX works normally, but OSD doesn't show data
Open the UART2 port in betaflight then the data can be displayed.
3. What is the version of the firmware of S-Tower?
Flight Control Board: betaflight_SPRACING 3.1.02; OSD: MWOSD1.63; ESC board：A-H-30 BLHeli-S 16.5
4. Why is the quad vibrating when the throttle is at 40%?
1. Do what you can to enhance shock absorption because the gyroscope is very sensitive to vibrations.2. Use motors with less vibration.3. Configure the PID to minimize the vibration. You may reference some PID tuning guides which are available on internet.
Airplane ESC
Car ESC
Lightning
1. The car goes backward when the controller sends go forward instruction.
1. The connection of the cables which connecting to the motors should be reversed. 2. The steering system of the car differs to regular steering systems.
2. The motor suddenly stops while it's running
1. Check if the receiver is interfered and check the remain power of the battery. 2. Replace a new battery if the battery voltage is too low. 3. It can be over-heat protection is triggered. Wait a few minutes to have the ESC cooled off.
3. The motor is rapidly accelerated while the power is on, or the motor is jammed or lagged.
1. Replace battery with stronger discharge ability.2. Replace lower speed motor to increase reduction ratio. 3. Set the start mode to lower level.
4. The motor is vibrating but not started.
1. Check all the connections; 2. Check all soldering points; 3. Contact FLYCOLOR to repair.
Boat ESC
FlyMonster
1. When the boat is switched on, the ESC beeping sound can indicate numbers of battery cells, but the motor is not started
Reset the throttle range.
2. The ESC is functional without any alarm but the motor is not started.
1. Check the plug of motor cables or solder motor cables again. 2. Change a new motor.
3. When the boat is switched on, the ESC beeps (two beeps with short pause)
The battery voltage is too low to drive the boat. Replace it by a fully charged battery.
4. When the boat is switched on, the ESC beeps (two beeps with short pause)
1. Check the connection of signal cables and receiver. 2. Check transmitter and receiver make sure the communication is functional.
5. When the boat is switched on the ESC beeps constently.
Pull the throttle stick to bottom position or reset the throttle range.
6. When the motor is switched on the ESC beeps two long tones and two short tones.
Choose proper setting of throttle forward or backward.
7. The boat is running reversely
1. Switch any two cables of the three cables connecting ESC and motor. 2. Use remote controller or program card to reverse rotation of the motor.
8. The motor stops while the boat is running
1.Set proper value of Low Voltage Protection. When the protection is triggered the boat would be running at Low Power Mode. And it means you should retreat your boat.2. The boat should be running in the range of remote controller. Mind the battery voltage of the remote controller. If it drops magnif...
9. The motor stops while the boat is running
1. Check setting of remote controller. 2. Check the communication between controller and receiver. 3. Check if there is interference from other electronic devices. Try to reconnect power cable if the boat back to normal function. If the same issue occurs frequently it could be caused by strong elec...
10. The motor stops while the boat is running
Check the connections of battery plug, power cables and motor cables.
