The newer release of the PTS has the SX600 TX which is 6 channel and does have Expo and other functions.

It's not a bad package deal, especially now that the sim has been upgraded as well.

Yeah you can purchase the ARF (I have), but the RTF version offers a lot less resistance for a newbie pilot... and gives them that much less to contend with...

In either case a good going over of the plane is needed however.
