RE: Radio controlled servo?
Why don't you list all the requirements, including a description of the finished product and / or the purpose of the device? Throwing requirements one by one, will only turn off the people that are trying to help you.
Something else that need to be kept in front of you is that after September 11, 2001, we are all observing for "signs" of potential terrorist activity. With the current developments in RC systems, your requests can be interpreted the wrong way. Be open and clear with your project and nobody will mis-interpret your questions.
