RE: 4-channel parkflyer
Is he willing to build a kit? He could get something like a Dandy Sport from Mountain Models or the Magpie (all foam so no covering). Both get rave reviews and are about $50 plus building supplies.
Or have a look at the GWS E-starter. Also a great plane - can be had for ~$40.
If he's willing to spend a little more - Hobby Lobby has the mini telemaster ARF with two wings (aileron and non aileron) receiver ready for $190. That would give a lot of flexibility with the two wings.
There are lots of options that would probably work.
IMO that Superstar is pretty big for a park flyer.
