Right now i am flying my belt cp with the stock tx and rx. my next signifiacnt purchase will likley be a new tx/rx setup. as part of a previous post some mentioned that i would be well suited to my a 7ch if i ever plan to fly nitro. there is a possibility that i will get a nitro eventually, so my question is what do i need the 7th channel for?

For what its worth i am thinking about getting a spektum or airtronics 2.4ghz
