I have been browsing around alibaba.com and I found a foam toy airplane that claims to be control line.  I tried to ask the guy a few questions but there was a language barrier.  Im going to try talking to him again tommrow.  if you look at the picture you can see the leadouts and it appears as though they are string instead of wire so the batt. should be on the airplane itself.  no idea on cost or Min order qty.  Ill keep you guys posted if I find out more.

moq is 1000 units at $13 so nevermind 

The easiest way to read it is to go to the top of his web page and click on the word "English".  Works!!
