About this Plan

Scientific Mercury. Free flight gas cabin model. Wingspan 72 in, wing area 720 sq in.

The Mercury was a kit, first produced by Scientific in 1939. This here is a later redrawn plan from MB in May 1975.

Quote: "Old Timer Model of the Month: Scientific Mercury. Designed by Ben Shereshaw. Redrawn by Phil Bernhardt. Text by Bill Northrop.

The Mercury first appeared in Scientific Model Airplane Co advertisements in mid-summer of 1939. Although he was never mentioned in the ads, Ben Shereshaw was the designer.

Typically Shereshaw in its clean, functional lines, it was unlike Shereshaw in its exceptionally easy construction. Most of his designs, such as the Custom Cavalier (oz335)and the Nimbus (oz524), were nine and ten foot streamliners, and were also major building projects.

Close inspection of the incidence angles as shown on the original plans indicate a very small angular difference between wing and stab. However, the stab has a symmetrical section. Still, it is advisable to be very careful when installing the stab to avoid a 0-0 set-up. The climb would be great, but watch the transition!

The Mercury should make an excellent R/C design, and with the tail surface location, the installation could be well disguised. With a wing area of approximately 765 sq in, the maximum glow engine size would be a .30."

Note this plan is stamped "An Uncle Willies Plan".

* 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.
