At the large model show at La Ferte Alais in France a couple of years ago, somebody actually built a 1:1 R/C model of the Cri-Cri - not sure what the point was!!
In another example of the cross-over between model and full-size some guy put a couple of model gas turbines in place of the piston jobs and successfully flew it - must have been the world's smallest twin jet!!

I'll see if I can find any pics.

cheers
