The KO Propo 81252 - RF-502FH Super Module applies CPU control to improve signal behaviour in the transmitter. Instead of a basic resistor/transistor setup, it uses a power transistor to raise the electrical wave output for more reliable transmission.
CPU management offers tighter control over output timing and stability, which reduces noise and helps keep inputs accurate in demanding conditions.
A large heat sink is fitted to the module to keep temperatures down and preserve performance during longer sessions or club events.
The RF-502FH produces a more linear signal curve, improving the predictability of servo travel and making throttle and steering feel more natural.
