You can buy the patch cable for the e-flight transmitter for somewhere around $40 bucks. Honestly though I do not really think that is worth it. There are some links on the net of how to build your own using ppjoy. Also the LHS told me that horizon will be comming out with cables for the e-flight Tx's that will run around $10 bucks sometime next month in April. So if you need it now and you are handy, build one, if not spend the $40 and get one, or if you can wait a month then get the $10 one =)
