Back in the early 80s I designed and built Bostonians when I was 13 years old, and I still have the plans. So I scanned them onto my computer and traced them in Coreldraw. The first one is my favorite the Piper J3 Cub. This was a pretty good flyer outdoors but a little too heavy for indoors. I really like Bostonians, they are easy to build, look nice and fly great. As a young model builder they were great for improving my building skills and trimming abilities.

I will start building this plane today, and when I am done I will make the necessary corrections to plan and post it.

I started on the Boston Piper Cub and so far everything is going well. The design is simple and basic and so far the fuselage looks like the Peck Polymers Piper Cub. I am keeping it simple, but you could add the two side singers and one top stringer. Of course you could also add the struts, landing gear detail and fake engines. The fuselage is done and I am pretty happy with this old design but will have to make some minor changes to plan. So far she weighs 6 grams as shown. I will also post a picture of me launching my original Boston Cub back in 82. I built the first fuselage side over the plan using straight pins to hold everything and Elmers White glue. I really like the look of all the pins when building a model. I soaked the top rear longeron in ammonia/water to help with the curve and not to cause distortion of the lower longeron. When dried, I flipped the fuselage side around and built the second right on top separated by wax paper. When dried I sand both sides nice and smooth and make sure they are identical. Then comes the fun part, boxing up the fuselage. Nothing fancy just straight pins and good eyesight and of course a square here and there. When dried I remove the fuselage and glue the rear making sure the fuselage is straight. Then I begin adding the cross members. When done with the rear, I began on the front. This is a little tricky because of the curve. I cracked the front fuselage where the cowl is located. I also soaked the front longerons with ammonia/water to aid with bending. Then I added the bottom cross members followed by temporary top longerons. The temporary cross members will be removed once the cowl is in place. The cowl is a solid balsa block that is hollowed out with a dremel. The wheels are balsa from Shorty's Basement, great wheels by the way.

Today I built the flying surfaces outlines using laminated 1/16X1/32 balsa strips. I first soak in warm water for 1 hour then I use pins as a template. I glue the balsa strips together with Elmers and carefully pull the laminated balsa around the pins. I have all the other parts cut out and will begin on the flying surfaces tonight.

I have the Piper already for covering and the weight as shown is 13 grams. This class of Bostonian must weigh at least 14 grams, so I think it will make it once covered. I am making some final adjustments to the plans and will hopefully post it today, the covering will also begin today. The little Piper Cub is a Peck Peanut scale, and that is what this build is based off of. When I was younger I also designed a scale 25 inch Piper J-3 and a 54 inch Piper J-3. I never built the 25 inch version but built the 54 inch Cub. I had most of the frame built and gave it away to someone who turned it into a RC bird. If I get time in the future, I will scan those plans to my computer.

All structures are built per the plans and 3/4 dihedral is added to the wing.

It was a nice calm day so I decided to take my Boston Cub out for a test flight. I used 1/8 rubber and did not wind her up all the way since the field is a little on the small size for Bostonians. She pretty much flew off the board with a tiny bit of clay in the nose. The first test flight she flew a little further than I thought she would fly and the tail caught the bottom of a branch, very little damage. I then added my turn tab to the wing and flew her again. This time she flew nice and slow like the real cub and flew over a min. That is not bad for a test flight. Then I called it quits and went back home. I scanned my 54 inch Piper J3 Cub that I designed when I was younger and maybe I will build that. It is a simple design based off the Comet 54 inch kits.

Great flight photos--yellow is a great color for airplanes on a grass field.

SCIGS, That sure looks great in the air. I couldn't fly today due to chores, but tomorrow is another day. After seeing your airplane up there, I'm inspired to fly.
