As far as radios are concerned......
As I mentioend in the how 2 article, there are no known manufacturers that make receivers on the U.S. "ground" frequencies that are small enough work for TTTT.
If you notice on this page:

The GWS crystals available in the U.S. (leagally, that is) are all 72MHZ for airplanes only.
Your Kyosho radio is 27MHZ made by Futaba. This is important because you must get the right crystal for your transmitter. They usually come from: Futaba, JR, HiTec, and Sanwa. You also need to use FM frequencies. I think the Kyosho radios are AM.
Here is a chart to confuse you:

If we could somehow import or find a Japanese company to buy from, we could get the GWS 27MHZ crytals that are made for Japanese markets but still ONLY AIRCRAFT (see link above), but it still would not work in your Kyosho radio if it is AM.
Believe me, I have about 30 different radio transmitters laying around. If there was a way I could avoid buying another one, I would. If ANYONE knows a way around this PLEASE LET US KNOW!!!
The short answer is: In the U.S. you must buy an FM transmitter on 72MHZ and then buy the GWS receiver and crystal. Make sure the crystal matches the brand of transmitter you will be using.
