This is the KO Propo EX-1 KIY V2 Concept 2.4GHz FHSS Radio System. KO PROPO introduces the Kustomize It Yourself (K.I.Y.) interchangeable transmitter system. The concept of the K.I.Y. brings simplicity to customizing and upgrading within a modular system. The transmitter is composed of 3 modular units: Steering, Throttle and Master units. The three separate modular units can be put together easily, with no screws required! Just push the safety lock of the joint, pull the lever and pull or push to insert or remove the modular unit. Ití s that simple! You can use the K.I.Y. to unlock your next system and bring more enjoyment to your hobby.

The included KR-411FH is a four channel micro receiver using KO's Frequency Hopping Spread Spectrum system that is compatible with the RF-903FH or RF-904FH modules.

Version 2 changes:

  • Version 2 is a software improvement for response and linear feeling.
  • Conventional response increased 5%. Transition from moving the steering back/forth quickly and small movements have been improved.
  • Motion feeling has been enhanced. Improvement for human interface for a more natural feeling but still maintaining a faster feeling.
  • Version 2 Master Units (FHSS & ASF) are compatible with current Grip and Steering Units.
  • External plastic case is the same as previous version, just software and PC board have been changed. 

EX-1 KIY Features:

  • High Performance CPU & 2.7inch LCD: Adopting a new CPU that is 20% faster then the previous system.

KO Propo EX-1 KIY V2 Concept 2.4GHz FHSS Radio System w/KR-411FH Micro Receiver
This is by far the biggest $550 disappointment I have ever hade.
I purchased this pice of junk less than 2 months ago and the
Second week I hade it I was sending it back to kopropo because
Of the throttle issue it was having, not to long after I got it
Back from Ko it was broke again. The K.I.Y. Has let me down
At some big races I.E motorama, and other trophy races.
