i just bought Real flight 7 with the just the interface package. im trying to set up my DX7s but everytime....... basically is there a set up video or a guide on how to set it up thank you
Welcome to RCH! Here is a video by rc-help.com's owner Tony...The video uses realflight 6.5 and the Spektrum DX8. Realflight 7 and the Spektrum DX7s should be a very similar setup.
Here is the video link(I hope this helps you):
