Sanwa (Airtronics) MT-4 Telemetry 2.4GHz FHSS-4T 4CH Surface Radio

Sanwa (Airtronics) MT-4 Telemetry 2.4GHz FHSS-4T 4CH Surface Radio
Sanwa (Airtronics) MT-4 Telemetry 2.4GHz FHSS-4T 4CH Surface Radio

 Sanwa MT-4 Telemetry 2.4GHz FHSS-4T 4CH Surface Radio

The Sanwa MT-4 4-Channel 2.4GHz FHSS-4 radio control system is the first 2.4GHz pistol grip radio to provide telemetry, industry leading latency, SSR (narrow pulse-width, super fast servo response) compatibility and 4 channels with advanced programming, all in one ultra-lightweight, comfortable case.

The feature set of the MT-4 is like no other radio in our hobby today. When used with the included Sanwa RX461 (92010) FHSS-4 receiver, real-time telemetry tells you what you need to know when you need to know it. In addition, the MT-4 supports Airtronics' FHSS-2 and FHSS-3 modulation types, so it will work with any Sanwa/Airtronics 2.4GHz FHSS-2 and FHSS-3 surface receiver as well (just no telemetry of course). This means you'll have your choice of affordable aftermarket receivers and high performance ultra-fast racing receivers to use with the radio. And, all of this is packed into a new ultra-lightweight comfortable case that features an integrated antenna, adjustable grips, adjustable steering and an adjustable trigger.

Whether you're racing at a world-class level, rock crawling over the most complicated courses, or just bashing in the backyard, the MT-4 will do what you need when you need.

We bought two of these for use on Savage Flux and E-Revo - they work like charm, but keep in mind that you have to change the S-Trim TH value (only tried at 100), else the speed won't initialize and it will seem something doesn't work. It is not mentioned in the manual, we found it while we read something in the CastleLink Software :) Price is perfect, quality is very professional and it looks sturdy and well built. My only gripe is that it doesn't have screen illumination, but I saw some China company offers ready to install set to fix that.
