About this Plan

Big Old Bipe. Radio control sport biplane model. Wingspan 74.5 in, wing area 1750 sq in. For 1.20 - 1.80 4-stroke or 25 cc gas engine.

Direct submission to Outerzone.

Scan by MarkD, cleanup by Circlip.

Note when this plan was published in the pages of RCM, large areas of the plan were obscured - see David Terrell's page at: for more details. Until someone finds and scans a full size paper plan, this will be the best we can do.

Quote: "In the 1920's and 30's, civilian and military biplanes could often be seen at airshows and were always crowd pleasers. Their pilots were dashing heroes in the eyes of the spectators, particularly young kids. The air of adventure, daring, glamour and independence associated with these biplane pilots was the stuff of newsreels, newspaper articles, and radio shows.

As kids we would dash to the local grass strip whenever a Swallow, Waco, Travel Air, Eaglerock etc, flew in. Just to spot one in the air was a thrill but to actually see one up close (airports had no fences and we could actually touch the airplanes) and to watch the dashing pilots walk around was a thrill beyond compare.

That era of aviation was marked by a fierce independence. No flightplans or limited air spaces, no multiple page forms to fill out, no electronic gadgets to fool with, no worries about liability suits, and no (or at least very few) nit-picking rules or regulations to mess with. Navigation was entirely IFR (I Follow Railroads). These heroes of the air were free to fly when they wanted and whew the freedom of flight took them.

Aviation was an activity that attracted free spirits who loved to fly simply because they were free. That they were people of unusual daring possessed by over-active egos is also rather obvious considering some of the audacious flying feats the media fed on in those days. Seemingly, the common denominator for pilots of that long ago era was their freedom.

We're speaking of an era when biplanes were fabric-covered and brightly colored. They were big and powered with large engines of limited power but unlimited noise-making ability. Funny thing, the restorations and reproductions of these old favorite biplanes don't seem nearly as large when we see them now. Today's tiny acrobatic, highly overpowered biplanes are not par of this macho hero image.

You must admit, big biplane models retain some of that spirit of the 20's and 30's, at least that is what we have attempted to capture in the Big Old Bipe. There is something very special about seeing this model in the air or on the ground. It's not fancy or particularly aerodynamically clean, but it most certainly recalls that wonderful long-ago era.

The guys at my flying field kept asking me what I was going to call this model. Frankly, I hated to call it a 'Bandito Bipe' to avoid repetition and confusion. I noticed that, lacking a name, they would refer to it as that 'big old bipe.' Sounded good to me; so I decided that was the name. However, that is a bit of a mouthful, so the model finally became simply 'BOB.' I sort of like that; it's not a bit pretentious or fancy and neither is the model - somehow the name fits.

Much of the aerodynamic layout for BOB is historically linked to the '4-120 Bipe' kit I designed for Ace many years ago. That it is a good one is attested to by the large number of those kits built and how many of them are still flying. Esthetically, there is more than a little Bandito Grande (oz7485) in BOB as well...

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.

REALLY was a pain to clean this one. Wing panel 'Generated' by cut, horizontal flip, erase and paste from other half, also cleaning 'Ghost' logo.

Rarely do the people who take the trouble to make these plans presentable at least, receive enough thanks for the work they do! The next time you click the download button, please give the guy a thought, he deserves that and more.
Humming I Say A Little Prayer For You right now ;)

Thank you for all the work but where are the landing gear?

The LG is missing because, quote: "Note when this plan was published in the pages of RCM, large areas of the plan were obscured." I've also included a link to David Terrell's page for more details on this, where David says: "The facsimile in the magazine partially obscures pages 1 and 3. The effect in page 1 cuts off one turtledeck bulkhead and the landing gear; while in page 2 the effect eliminates one side of the upper wing."

* 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.
