They also carry a budget receiver by Hitec called the Mini 6S. The Hitec Mini 6S is a single conversion model that is designed for full range flying. It is also shift selectable like the GWS RS8DL so you don't have to worry about shopping for a Futaba/Tower/Hitec or JR/Airtronics model, it will work with both. The Mini 6S is actually an auto-shift receiver that detects your radio signal type and switches automatically.

At $36 for receiver plus crystal, this would probably be a pretty good choice for anyone looking for a budget receiver that didn't want to order the GWS model from Hong Kong. I personally have never used the Mini 6S before, but I like Hitec's receiver products and I'd try one of this out in the right project.

For a sport plane or trainer, the Mini 6S by Hitec would probably prove to be a good, reliable receiver for any kind of 72Mhz FM radio system. It has the tab slots to accept Futaba servo connectors, as well.

With the Hitec Supreme IIS available for just $12 more, however, most pilots prefer to opt for the Dual Conversion model with two extra channels on it.
