Record Hound (oz5079)
About this Plan
Record Hound. Free flight gas model. Redrawn for MB in 1976.
The Record Hound (oz24) was first published in August 1939 Air Trails. This here is a later redrawn plan from MB 1976.
Quote: "OLD TIMER Model of the Month. Designed by Henry Struck. Redrawn by: Al Patterson. Text by Bill Northrop.
Though not as well known as some of the more popular Struck designs, the 'Record Hound' had an unusually business-like appearance and incorporated many new ideas in design and construction techniques. Being true to its name, it set a 1939 NAA (before AMA was established) record with a three-flight average of 5:41, and this in relatively dead, mid-winter Eastern air.
The Record Hound was published in the August 1939 issue of Air Trails, from which our plans were drawn. Construction of the flying surfaces is pretty conventional except for the rib stiffeners - not caps as we use today, but rather, strips of 1/16 x 3/16 glued perpendicularly along the side of each 1/16 sheet rib.
Without the four-step isometric drawings in the article, you may need help on the fuselage. The upper and lower frames are built first, over the plans. (Note that longerons overhang front crosspieces by 3/32 of an inch). The upper frame is then removed and moun-ted over the lower frame, using tem-porary spacers to maintain correct height while the uprights are installed. Next add the plywood firewall bulkhead. Now soak the bottom longeron in water and then run it over a soldering iron or other hot metal until you have the approxi-mate side-view shape. Mount the longeron by gluing to the firewalt and fitting temporary vertical braces. Cut actual uprights to approximate length, glue in place against the corners of the longeron, and trim off bottoms when dry. Now cover the upper frame sides with 1/16 sheet. Finally, a 3/16 x 3/4 soft balsa cap strip is added to the bottom, side stringers of 1/8 x 1/4 are glued on, and miscellaneous fillets are added.
For once, we're not going to say that the O.T. Model of the Month will make a good R/C model - it just ain't the type!"
Supplementary file notes
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
