Rather than looking for another Focus a far more advantageous Hitec to look for on the used market would be a Hitec Prism 7X with a synthesized module. These were among Hitec's earliest computer radios and are very cheap on the market. Now unlike the Focus which essentially is a one airplane one transmitter set up the Prism 7x is an extremely versatile FM radio that has strorage for three airplanes and is selectable between the the three airplane with just two button pushs. Not only that it will also function with Futaba FM (PPM) receivers which are also by factory default negative shift receivers but the Prism 7X is also shift selectable so it can function with both Airtronics and JR FM (PPM) positive shift receivers.

Now remember I mentioned that Prism 7X with the synthesized module? Well the synthesized removable module means you ca set two manual knobs and select any frequency on the 72 MHz band. No more chasing around looking for a tranny on such and such frequency. OK now for the best part. If you can find a 7x that means it is a module type radio and that Synth module can be changed out for a Hitec 2.4 module at anytime.

This Radio offer also V tail, elevon and airleron to rudder mixs. Dual rates on not only elevator and aileron but also rudder, and of course Expotentiial on all three axis. All this stuff you will be wanting to explore sooner or latter rest assured.

I still have three of these and still use them, two of which I use around my reck with a side strap setup so the radio is used for controlline flying primarily throttle and some other functions in one case airplane release (stooge release or break release if you will).

These radios have not gone for much in these here parts around thirty bucks and remember if you get the 7x with the synthesized module you won,t have to go looking for crystals.
