Well due to some time problems, and my computer currently dieing a slow death, it looks like the white paper wont happen any time soon...
however this site will give lots of good info on the ins and outs of most r/c radios, and if you look closely you will also see that our radios have an 7 channel encoder.. all you have to do is interface with the extra pins (unground them first btw)
