This is an Airtronics M12 2.4GHz FH4T 4-Channel Competition Pistol Grip Radio with RX-471 FH4 Super Response Receiver. The M12 is newly-equipped with a 4x higher spec CPU compared to our world champion model, the industry-leading M11X. Brand new from the ground-up, the M12 is the realization of lofty goals to more than double its analysis ablility and speed.

The Airtronics 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.

This is an Airtronics SD-6G Crawler 6-Channel 2.4GHz FHSS-1 Surface Radio. The SD-6G Crawler system is electronically the same as the SD-6G aircraft system, however, this version has been modified to allow maximum flexibility for four wheel steering, as well as dig/independent motor control for crawlers with individual front and rear motors.
