About this Plan

Dakota. Free flight sport biplane model.

The Dakota is a famous half-A gas sport free flight biplane by Joe Wagner, kitted by Veco and first designed in 1947. This here is a later print with following title block: "Dakota. Reconstructed Original Design, 24 Sept 1974. Drawn by Joe Wagner. Rev for Modern Motors March 83."

Quote: "The Dakota was originally designed in September, 1949. The first configuration was exactly as depicted here, with two exceptions: the engine was one of the first-model OK Cub .O49's; and the landing gear wire was identical to that of the Veco Papoose (which had been over-optimistically ordered).

The Dakota was designed specifically as a kit model for Veco (Henry Engineering Co) and was their first free-flight kit, as well as Joe Wagner's first design to be kitted. All design work, construction, test flying, however, was done after 'working hours'. No payment or royalty for this model has ever been received by the designer, even though it is the longest-lived free-flight model kit ever made: on the market continuously for 25 years!

Construction quirks: The wing ribs were made with 1/4 in extra depth so as to be stiff enough to hold the wing aft sheeting to the right curvature while the cement dries. Hence, the leading edges need to be blocked up 1/4 in off the building board during wing assembly.

The wing ribs are trimmed off level with the bottom of the leading edge when the wing assemblies are dry, before installing in the fuselage. Also, taper the bottom of each leading edge from the outer rib to the tip. *Do not* cover the wings on the bottom.

Flying: The 'Dakota' is supposed to circle left under power and right in the glide. Propeller torque and the engine's left thrust will turn the model left under power, while the nose is prevented from dropping into a spiral dive by a combination of gyroscopic and slipstream forces plus right rudder tab.

This is a 'small-field model', designed for tight circling; its glide is slow but fairly steep so it is unlikely to soar out of sight in a thermal. Even with a long engine run. [signed] Joe Wagner."

My Dakota was built from the Veco kit around '60 or '61, powered with a Pee Wee 020 mounted inverted, later to be a big problem. Test glides didn't go all that well over the proverbial tall grass, and so I decided to just let it take off from the street in front of Girard Jr High. Another big mistake. After a perfect takeoff run, it lifted off just enough to catch the top lip of a concrete curb on the opposite side of the street, bending the inverted Pee Wee cylinder, which never ran again. I don't remember what happened to the undamaged Dakota but it took me many months of paper route savings before I could buy another engine, this time a hand-me-down Cox 049, not another Pee Wee. Those 049's were much more available in my neighborhood a few days after Christmas once the plastic models were destroyed, leaving the undamaged engines for sale cheap. Our most fun with the surplus 049's were in crude U-control models made from cardboard and tape, didn't fly all that well but were indestructible if flown over grass. One of us would fly the plane while our buddies would try to throw rags and knock it out of the air. The Top Flite nylon props would bend but never break, lots of low cost afternoon fun...

I can't remember if I was in Jr. High or High School but somewhere around 1969-1972 (12-14 yrs old ) I built the Dakota from the Veco kit and will never forget the day my dad took us to the Hobby Shop in San Jose, CA on Hillsdale Ave to buy it. The hobby shop had a nicely painted Dakota hanging which I always admired when I rode my bike to the shopping center to 'window shop' ( what happened to all the great stores from back then ) ; it was a kind of metallic copper colored paint with black trim lines going down the fuse. We also bought a Cox tee-dee .020 there to power it. I built it as fast as I could and doped it only with enough clear butyrate to protect the balsa.
After breaking in the .020, we went out to the high school (Leigh) to maiden it ( back when there were no rules about flying model planes ). The beautiful TD .020 with the grey glass-filled 5x4 prop started up and I adjusted the needle valve to 'just a little rich', hand-launched it and apparently everything was trimmed perfectly as it began its tight left-circling climb with that red tank full of Cox 25% (?) Nitro . When the motor finally quit, it must have been about 100-200 feet up there, and startled us by gliding perfectly straight into the (very slight ) wind, right towards the houses south of the field !! My dad piled us in the car and we drove over to where we last saw it heading. What happened next was unbelievable but absolutely true: We drove down one of the streets and found the Dakota had *LANDED IN THE STREET* perfectly!!!! ( Back then there were trees and telephone poles and electrical wires running all through the neighborhoods; how it managed to dodge all of them was beyond me ). There were a few kids running around yelling and pointing at the plane so fortunately not enough time had elapsed for them to 'claim it', lol. I will never forget that Dakota and plan on building an electric version soon either with some plans that I already have or from the BMJR kit.

Peter D, Amazing story! Yes, I was taken by my father to that very Hobby Shop in downtown San Jose! In '72, we bought a Jetco Thermic 50... I have the BMJR Dakota, will be 3 channel electric - and you just motivated me to build:-)

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.
