Old Scientific Mercury Kit

Hi All,

Just returned from the Vintage R/C Society reunion at Endicott NY. We had a great time there.

While there, I acquired an very old kit. A "Scientific Mercury" with 72 inch WS. The contents of the kit box are complete , including the old wooden hubbed wheels which are still in very good condition. Wood is very good as well. The only part not good is the kit box. It looks a little ragged. I guess this spoils the value as a collector item, so I plan to build the kit.

Does anyone have any info about the history of this model? I would like to know as much as possible about the plane, the designer, & the kit company.

This plane was designed by Ben Shereshaw and was first kitted in 1939 by Scientific. In my opinion it is one of the most classic oldtimers. I'd suggest using the kit as patterns to cut parts from new wood since its so old.

Here's a picture Ben himself holding a Mercury that was built as electric for him by his son who posted it here on RCGroups. I think it is slightly reduced in scale from the original. The Brown Jr motor in the photo is a dummy cylinder

Mercury at SAM Champs Las Vegas 2001

Here is a picture of about 9 Mercurys at the SAM Champs
a few years ago. Ben was there being honored for his contribution to Model designs.
All flew quite well. Can't remember which one was the winnner of the Concourse. All models entered in the Concourse must be flown during the Champs to prove that
they are a flyable model.

The "JR"..........

I have the '39 Scientific Mercury Jr. kit. Same as it's "big-Brother", but at a 50" span( didn't get the public fanfare the bigger sibling got, being class A). A simple geared 400 is all it needs to be airborne. I've built a couple copys from the printwood in the past, and even with 6.3oz of NiCads she's a "floater".
Oh Yes. NEVER use your origional printwood! when it's gone. it's GONE!
Try my method of copying the printwood. You can use MUCH beter graded contest wood, and it will be EXACTLY the same as the kit wood... well, almost. The ONLY thing that will be different is the numbers or letters will be "mirrored" or reversed. and a couple of swipes from fine sandpaper will eliminate that. Or, if you want people to see them (some do) all you need do is take your copies to the CAD /blueprint shop and have them reverse-copy them. when laid-out you can't tell it from the origional printwood!
AND.. as long as you keep a printwood photocopy, you'll always have a virtual "short-kit" on paper to rebuild her!
Here's a link to my method (I really need to use my new camera and retake & edit the photos in it, they're a few years old, when I had a "cheapy-digital" )

Hello Bob,,,,, Quite a while back you made me an offer regarding 'a coke bottle cowling' you constructed for your Mercury. The Merc is so close to the Sportster I wish now I had taken you up on the offer! I followed your thread, and read the posts regarding the forming bit. If you have an extra Cowling available I would gladly pay! Save myself of the expense of Dremel, Coke, and Heat Gun. Take care.
