Moving Forward - Then Back


The Firewall was glued in place followed by the middle top former. An alignment stick was taped in place and the IP former added, using the stick to insure the alignment.

Then it was back to the tail where machinists squares are used to align the tail post. The post was held in place with a cloths pin and glued together.

Starting on the Strings


The top stringers were added beginning with the shaped upper cabin stringers. From there, the rest of the stringers were added, then the aluminum wing joiner tubes were fitted and glued in place.

Cutting In the Hatch and Mounting the Servos


The equipment access hatch was added by cutting the stringers between the formers and the side stiffeners added. The servo rails were then added and the rudder and elevator servos mounted.

Next up, the landing gear.....

Servos are nicely tucked toward the back- that long nose sure helps out in that regard . I supposed Sparky is going to be doing his usual terrific job on the plastics...Are you going with a formed canopy on this one?

Cut it twice, still too short

There is something quite elegant in a stick frame fuse. Strong, light, beautiful. Another great job, Pat, but we kinda expected to see some pre-flight photos by now, after all you started this build three days ago!

Soldering Up the Landing Gear


The LG components were bent from 1/16 wire, fitted onto the fuselage and soldered together in place. A bass wood stick was clamped to the gear to hold it all in place for soldering.

And while we're at it, the tail wheel strut was shaped up and lashed to the tail post.

Finishing the Fuselage


The last thing up on the fuselage was to get the window frames in. As luck would have it, the frame JUST fits a file folder, so were cut from a folder rather then 1/64 ply. But for those who prefer ply to paper, go for it, it'll work fine to.

Then it was on to the cowl plug. The mold was carved from blue foam and is winging its way to Sparky even as we speak, so you know it's going to be nice. Will also include the spinner in the plastic parts pack.

Building Up the Tail Section


The vertical and horizontal stabs are both airfoiled so they'll be thick enough to be self supporting. The horizontal stab span is over 20", and being un-braced, I didn't think the flat plate style would be the way to go on this one. Once framed and sanded to shape, the rudder and elevator hinges were cut in to finish up the tail planes.

Getting Started on the Wings


The wings on the Porter are EASY! Just a simple Hershey Bar panel with flaps and ailerons the full lenth of the rear spar -- no cut in's or cut out's, just straight lines everywhere you look. After building the Stinson Reliant and a couple of Cessna's, this one is a no-brainer!

And yes, the flaps on this wing are HUGE!. The flap span is just shy of 17" with a 2" chord, so there's no doubt in my mind that the Porter is going to slow down real well.

The full scale Porter is also built with no dihedral. On the model I went with one degree as I've learned over the years that a flat wing on a model literaly kills the roll stability in level flight and the model will "hunt", requiring constant correction to maintain wings level. And the good news is that a flat wing looks droopy, with one degree of dihedral, they look flat.

Next up, the other wing -- then we'll be on the home stretch.
