Zipity Do Da (oz8128)
About this Plan
Zipity Do Da. Radio control sport tailless model. For .40 power. Wing area 896sq in. Simitar series design by Bill Evans.
Quote: "A 'Wing' for all the right reasons! If you haven't tried a Simitar Series Flying Wing yet, now is the time! By Bill Evans.
Though Simitars operate on the concept of a flying wing, they really don't look like a flying wing. Neither do they appear to be conventional in nature. So, what are they? They are 21st Century Aircraft of the Simitar Series.
Flying the Do-Da is pure pleasure. Some call it the K-12. That's Kindergarten through 12th grade. If you give low throttle and make slow, easy control input, it will respond as a glider. If you signal full power and give control input to the max, it's a screaming demon.
On one occasion I had landed the original one wheel version, dead stick and one of the Sierra Simitar Squadron members walked out to pick it up. The wind was blowing about 20 mph; as he approached the ship I gave some right to level the wing and, just for the fun of it, some down to lift the tail. Result was the wind pushed the ship backwards, in a reverse taxi mode, causing my retriever to run after it.
Another time, while flying the 85 in span, ST3000 version of the Do-Da, upon landing and taxiing in at low throttle the engine loaded up a bit. When given more throttle it backfired and reversed direction. We then proceeded to taxi toward the pit, tail first.
Now, add flying in winds up to 60 mph, hovering inverted, and backing up mid air in the same wind, to vertical landings: and vertical take-offs (recorded on VHS). To explain what the Do-Da can do in its entirety would take too long; to say what it cannot do is most simply put by saying -The Do-Da violates all limits of what some hold true.
Construction is super simple: foam core wing; fuselage sides, top and bottom of sheet balsa. It takes about six hours of work time for construction, complete, ready to cover. It then takes me at least six hours to cover..."

Corrections?
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

My son and I have built almost all of Bill Evans airplanes. The Zipity Do Da is one of his favorites [main pic, 003]. He has two of them, one four stroke (glow) and one two stroke (gas). The airplane handles the wind well and will do anything you ask it to. The build couldn’t be any easier, as is true with all of Bill's airplanes. If you don’t have a way to cut foam watch some videos, it’s a lot easier than you think. Remember it’s right here on Outerzone for you to recreate - try it out.Martin Kolm - 20/03/2022
I have a Zippidy do da that l scratch built about 15 or more years ago. It has grown a lot of hanger rash and l am now restoring it to as new condition. I love flying this design so much that l am going to build a 100 inch span version and power it with a Brison 30 cc gas /petrol engine. This model will be fitted with cameras and other equipment.
The very simplicity of the design makes a superbly beautiful aircraft that stands out in a crowd.
I love building so the wing will be constructed from balsa, glass and covered in polyester fabric (?-span).
I hope to get all the domestic chores done soon so l can start building

Notes
* 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.
Scaling
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.
