Construction appears conventional, However, the article offers a potpourri of techniques that are quite practical for use by those transitioning from heavier models (R/C, U/C) to free flight rubber.
Fuselage: Pin the plans to your building board and cover them with Saran Wrap'. Build the two fuselage sides by pinning the longerons to the board and fitting the uprights and 1/16 nose filler. Remember, we might pin through pieces on a large ship but never on these things. Make an 'X' from two pins across parts you are trying to hold. Apply a drop of cyano to each joint.
Some people build one side on top of the other. I always end up with a profile fuselage this way. I build separately and hope for identical sides. Next, place the sides upside down on your hoard resting where the wing goes. Install the cabin area cross pieces. A small drafting triangle helps here talso tiny fingers). Install formers 'A' and 'B'. Draw the tail together and install the remaining cross pieces. Sheet the top of the nose and fill the bottom between former A and the first cross piece, I usually sheet the nose in two pieces starting from the sides with a splice in the center.
Cut the noseblock from a piece of 1/4 inch thick balsa, Cut a rectangle from former A with a sharp X-Acto and glue this to the rear of the block. This becomes your alignment key for the nose and should be a snug fit. Squirt some cyano around the edges of the plug and hole to harden them. Drill a hole for the Peck Polymer thrust button in the nose. Bend the landing gear from music wire. I just go for a tight fit and use thick cyano to bond it to the uprights. A small gusset on the bottom on each leg finishes the job. if you feel better, make a balsa sandwich around the gear and glue it in. That's the only beefing-up you transitional types are allowed. More gussets and glue only make the project heavier and harder to fly. Trust me..."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
