Did a cursory search around RCU and found nothing on this amazing project.
How about a 18.5 foot, 114lb flying boat powered by 3 DA 50 engines?
Plus, they did a model of the Savoia Marchetti S.66 flying boat. (To the best of my knowledge, and I have done some research, this is the first R/C model ever done of the S.66. A friend and I have been doing some preliminary design on an 80" electric power version.)
An amazing project, for sure. The model is so large that they seem to have converted a boat trailer to haul it around...
Link to MAN blog about the monster S.66:
Plus a couple of pictures from the blog and a link to a youtube video about the model:
