What are the main features of the KR-415FHD receiver?

This receiver is designed for the world of competition. Its high response speed and greater range (compared to other receivers from the same manufacturer) are two of its main features, highly valued by professional pilots.

Without a doubt, its most remarkable and distinguishing feature is that the KR-415FHD has two internal micro-receivers that capture and process the encoded signal simultaneously, in parallel (hence the "Dual"). One receiver uses the visible coaxial antenna, while the other has an internal antenna. Therefore, in addition to its high response speed and maximum range, the KR-415FHD boasts significantly greater reliability than its predecessors.

Finally, it's worth highlighting a very useful detail. The receiver box itself has a custom-made hole for attaching the protective sleeve (rod) of the external coaxial antenna. As you can see, all these features have made the KR-415FHD receiver a key component in the equipment of the most demanding pilots.

What is HCS Mode and how can we activate it on this receiver?

KO Propo has developed a new communication system between the receiver and the servo with the aim of making the transmission speed of the compressed signal between them even faster.
This system is called HCS and we can activate it on any of the 4 available channels on this receiver using a device, the HCS Mode Selector (16031) which is sold separately.

The digital servo connected to any of the four channels of this receiver will automatically recognize the currently active mode (Normal/HCS). By default, the receiver operates in Normal mode. Therefore, no activation is required on the servo. It is important to note that HCS mode is only recognized by the latest generation of servos manufactured by KO Propo, specifically the following models: RSx3 PowerHC, RSX3 ResponseHC, RSX3 Power, RSX3 Response, BSx3 One10 Grasper, and RSx3-12.

In which categories within the RC do we recommend this receiver?

Having reviewed its specifications and considering the excellent performance of the KR-415FHD receiver, it's clear that this product is geared towards high-level competition. Therefore, we recommend this receiver for categories such as: 1/8 TT Nitro/EP, 1/10 Touring EP/GP, 1/10 F1 EP, 1/12 EP, Pro10 EP, 1/8 GP, 1/5 GP, and 1/5 TT GP.
