FHSS logo

KO PROPO’s new hybrid 2.4GHz system.
With the merit of KO's DS-SS (Direct Sequence-Spread Spectrum) knowledge, the introduction of KO's FH-SS (Frequency Hopping-Spread Spectrum) allows for a stronger performance against interference. Create a better response and comfort by updating your transmitter’s module and receiver. We offer you the best performance system with the new system.

Easier to hit the driving line.
KO PROPO FHSS allows you to experience a clean response. Your vehicle will turn beautifully in the corners.
Each module has a different hopping pattern.
Having different hopping patterns avoids interference. You can operate this system amongst 50 other vehicles.
160m is 2x the distance of our former line up.
The operation distance is greatly improved by optimizing the telecommunication system.
The binding time is greatly reduced to 0.01 seconds or less.
Turn it on and drive it.
