Futaba 2.4GHz FASST radio system or module/receiver set, you've selected a fully tested, well-engineered, totally reliable product - one that's absolutely ready to give demanding R/C hobbyists the performance they expect. Our hands-on experience with 2.4GHz technology stretches back 15 years, long before anyone considered its value in hobby applications. That's when engineers in Futaba's industrial R/C division - designers of radio-control tools for construction, civil engineering, and similar uses - began employing and perfecting their own 2.4GHz equipment. Those same engineers were brought in to share their knowledge as soon as we were comfortable that 2.4GHz technology had perfected for the unique demands of R/C hobby applications. No other radio manufacturer had such an instant supply of expertise.
