Frequently Asked Questions

What is the operating voltage range for the HOTRC DS-4A transmitter and F-04A receiver?

Both the DS-4A transmitter and the F-04A receiver operate on a wide voltage range of 4 to 9 volts DC. This allows for flexible power source options, including standard AA battery packs or 2S LiPo batteries with appropriate voltage regulation.

What type of output signal does the F-04A receiver provide?

The F-04A receiver provides standard Pulse Width Modulation (PWM) output signals on its four channels. This signal type is directly compatible with most servos, brushed electronic speed controllers (ESCs), and other actuators commonly used in RC models and automation.

What is the effective control range of this HOTRC radio system?

The system offers an approximate ground-level control range of 300 meters (about 1000 feet) under ideal conditions. Actual range can be affected by environmental factors such as obstacles, interference from other 2.4GHz devices, and antenna orientation.

Is this system compatible with drone flight controllers?

The F-04A receiver outputs standard PWM signals, which are compatible with flight controllers that have PWM input ports, such as some older or simpler flight control boards. For modern Betaflight or ArduPilot setups, a PWM-to-SBUS or PWM-to-PPM encoder/converter may be required for direct integration.
