Tim, yes my plans are a design of Al Masters. I know Don Smith has a set of plans out there that have a 98" wing span but I have yet to find any information on the net from a person who has build his plans. By the look of the AMA plans list there are a few assorted plans out there as well but most of those are smaller. I do know the major difference between the Al Masters and the Don Smith plans is that the rear engine of the Don Smith plans is actually located inside the fuselage just behind F15 like the real aircraft's where as the Al Masters set places the rear engine after the tail at F20 under the cowl.

Speaking of engines here are a couple photos of the front firewall work I had to do to make the larger front engine fit. I used the front firewall to bascilly hold the airframe together and give me a mounting location for the front cowl, but I cut a hole through it and made a new firewall 1" behind the original firewall. This eats up room in area where my front fuel tank and control servos were to be mounted, I fear I might have to move a servo or two underneth my cockpit. Moving the firewall back an 1" allows me to keep the overall length the same and saves the mounting location of the front cowel, I will have to see if this all pays off or comes back to bite me.
