How to Troubleshoot RC Aircraft Signal Loss or Poor Connection

1. Check if the antennas of the transmitter and receiver are damaged, especially the ones on the receiver.

The silver part at the front of the antennas is the most important as it's the feeder line.

If the feeder line is damaged, keep flying will cause the unstable internal current which weaken the signal.

2. Check the RSSI value

Power on the transmitter and receiver with both antennas parallel and straight and within the distance of 30 centimeters as picture below.

3. Check the flight environment if the antennas are all right and the RSSI value is normal within the range

• Check if there is an electricity substation or high voltage cable, or wifi nearby.
• Check if the antenna of transmitter and receiver is damaged or welded joint.
• Installation: Do not get the receiver close to the ESC/galvanometer/metal part of the flight.
• Let the end of the receiver antenna droop out to avoid the signal being blocked by the flight

frame.
