Futaba 4EXA FM R/C Radio System

http://www.futaba-rc.com It’s more than a great system for a first model. Four-model memory also makes it great system for a second, third and fourth model, too. Switching from one model to another doesn’t require a time-wasting reset — just a push-button and a few seconds. The 4EXA not only does the work of four 4-channel systems for a single price: it also delivers digital set-up precision most systems don’t offer and a list of enhanced performance features other sport systems can’t match.
