I have the Nosen Mulligan and several other of his kits but haven't started them yet. I did build the trainer and Gere Sport years ago. Those kits where designed and first marketed when there wasn't muck to power giant scale and about all of them flew on a good 60 engine. The Mulligan makes a very nice looking plane and if I remember correctly most people add some strength to them when they put a gas engine in them, especially the front.
Here is a link to some info on the kit:

This one has some shots of one in the bones.

There are ones for sale pretty often on Ebay.
Hope this helps!
