Sportster Bipe (oz6672)
About this Plan
Sportster Bipe. Radio control sport biplane model. Wing area 716 sq in, for .40 power with 4 channel radio. Discontinued kit from Great Planes.
Quote: "The Sportster Bipe 40 was designed for sport flying. This biplane design with symmetrical wings provides full aerobatic maneuverability, yet has enough wing area for docile low speed capability.
The parts are machine cut and sanded for accurate fit. Should you notice a difference in size between plans and parts, it is usually because paper changes size with moisture.
Different types of glue may be used such as epoxy, cyanoacrylate (instant glue) and aliphatic resin (white glue). Build on a flat surface for straight wings and fuselage.
Please read through this step-by-step instruction manual before you start building so you will have an overall idea of the construction steps and to avoid mistakes. Use the plan and parts list to identify the various parts..."
Update 10/04/2018: Added kit manual (32 pages) from hobbico site (discontinued kits section) at manuals.hobbico.com/gpm/sportster-bipe-40-manual.pdf
Quote: "This one is sort of like a scaled down Aeromaster. Sportster Bipe 40 been out of production for years. Would hate to see the design lost to time."
Update 03/04/2019: Added PDFvector plan tracing and CAD file (includes 3rd sheet showing all parts), thanks to AlanSinclair.

User commentsI built one of these back around 1990 and powered it with an OS 48 Surpass 4 stroke. This seemed like an ideal power plant giving plenty of performance (though not compared to today's 3D style of flying of course) and the CG was perfect with no additional trim ballast required. The Sportster Bipe is a beautiful flying aircraft that is quite stable and easy to land yet can be tossed around to give a nice aerobatic performance and being a biplane it looks larger in the air than it actually is. It's a real pity that Great Planes discontinued the model. Definitely worth the effort of scratch building if you want one.

* 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.
