I have invented a truly interference free system. It also uses special circuits to detect the voltage in the servo cables and will amplify this to keep it constant 4.8 volts. It also ensures no possible problem with someone using the same frequency, as there is no way this can happen.

My only problem is finding a way to reel out the cable that attaches to the model from the control unit...........[:@]

Our problem is that there are so many frequencies and transmission methods being employed, that because we are such a small user, we will be totally at the mercy of the manufacturers who wishing to stay in business, will plump for control systems for the mass market. Unless some government directive removes us from where we are, I do think it will be a long long time before we make a leap into different technologies with much greater safety.

Do I understand correctly that because of its cleverness,the Powerbox can actually enhance the range at which quality signal can be captured? How does it do that? Or did that refer to the signal integrity from reciept to servo?

There appears to be a bit more to these PB designs, maybe should run a seperate thread on them....
