Just curious saw your posting.I have the Ray Dehn plane from the 12/75 RCM mag.Don't know what to do got it at a swap,fuselage part built,has set of foam wing blocks cut by some outfit that does that.Apparently being built from the plans 3 big sheets,he even had the RCM mag that featured it.Looks like a real bear to build,supposed to have retracts etc.interesting that it was only powered by a ST 61 today would be considered awful small by todays standards.I had posted to see if anyone had any experience with this plane but got no replies.Wonder if it is the same plane as you have as it is a 64" also.They are a really neat plane but there isn't much in line of kits for them.
