The model is an early RC design ... I still marvel at the bravery needed to throw the whole thing into the air and "pray" it stays up there while the RC gear kicked in.. it has a 51" ws and used a K&B 15 .. designed by Vince Micchia ..
There is a build thread on RC Groups for an electric conversion..
will combine shipping
