Matt, You're right, I'm not in USA.
Rcinsight, I've done the Google search, sigh no useful results, except that I found out it was popular in Germany.
Edseb you're right too, 40 MHz is banned in USA.
This is for a friend who got the radio used with a car he bought, he wants to use the radio on another car but we can't reverse the throttle servo.
It's not like I'm a beginner, but I still need the F... F... Friendly manual. Actually it looks like a pretty good radio with 10 model memory and all. If one could just figure out how to use it. It says Asahi Radio on the box, but Google has not given me any useful links on that either.
