"... I currently have an Airtronics RD6000 radio. Do you see any problems using this transmitter with either the hitech or eflight receivers? Can I take a crystal from one of my existing airtronics receivers and use it in the other receivers, or just purchase that receivers crystal for my channel number, or would it matter? thanks again."


It appears that your radio can work with PPM or PCM schemes, so you should have no trouble getting either a Hitech or Eflight receiver to work with it. I see that Hitech has a 6 channel mini receiver with an autoshift detect feature that works with PPM. If you were to go with this receiver, you should also purchase Hitech's matching crystal for the channel you are interested in. That will ensure that you will be on the right channel frequency. For maximum flexibility, you might consider a synthesized receiver that will work on any channel. However, these appear to be more expensive and not as compact as the others.
