The cardboard sauceboat designs in this Holy Scripture meet completely three engineering that had to be solved for the boats to be successfully constructed with cardboard. Design and build a human powered boat made of cardboard which is capable of completing at least unity spark around a abruptly.
WHEN I WAS a much younger kid, I would scrounge up anything I could to build something that resembled an RC model. Now in my 30s, people probably thought I sounded like a 9-year-old a couple years ago when I said, “I’m gonna build a really big RC airplane outta cardboard and pine. The idea of using cardboard came from my school days, when I built an airplane wing cross-section from poster board for use as a visual aid.
Designing the Cardboard Condor was mainly a combination of building and design experience, experimenting with the materials to be used, and basic formulas for surface area. Another design requirement was that this 12.5-foot-wingspan airplane had to fit into my Pontiac Vibe. All servos used nylon or Karbonite gears, with the exception of the metal-geared elevator servo. I wasn’t keen on the idea of spending the money on the two areas where I did have to deviate to costly aircraft-grade plywood: select wing ribs and the engine nacelles. A potential safety hazard is created without the instant ability to stop all engines using the transmitter during starting. I had originally installed brass sleeve inserts in the frame to receive the nose strut, but the strut tended to bind in the sleeves when its wheel experienced any side loads. As I got closer to the reality of how 50 pounds felt as I built, I made more changes to lighten things. In keeping with the theme of simplicity, the engine nacelle-mounting and wing mounting methods involved the use of screw-and-nut fasteners through holes drilled into the wing.
There was a good amount of preparation to determine what checklists I wanted to go through one more time at this point. I stood at a point along the runway where I decided to abort my takeoff attempt if the airplane wasn’t off of the ground with a healthy head of flying speed. I tried a couple of fast taxis and then checked the model one last time for anything that may have come loose that didn’t shake out during engine break-in or other testing. Every fiber of my being wanted to jam that throttle forward to see if this thing would fly. I ended up making small adjustments on a couple throttle linkages to fine-tune the engine synchronization. Coming down on the backside the first time was a little scary; I wasn’t sure what to expect. The four engines get a workout during flight, requiring me to apply much more throttle than I normally use to fly a singleengine, 60-size model.
I hope this project encourages you to consider new directions in which you can take your RC flying.
To read the complete story how the author designed, tested, built, and flew this unique aircraft, go to the September 2009 issue of Model Aviation. This free plan collection (see my others at the bottom) herds all the free cat furniture plans I could find into nice neat categories. So there’s a rarely mentioned issue in the cat furniture world so I assume there must be some kind of taboo about it.
This is a phenomenally well produced free PDF, complete with sketches and guides for building your own cat enclosures.
All of these great ideas are so marvelous…thanks to each of you who have inspired me more to make one of my own!!! Hi Deborah, thanks for your comment and please send us pictures when you finish your palace! Maybe you could try making the frame out of plastic (pvc pipe, plastice crates, etc.) and then have carpeted or cloth sections that you can take on and off to wash. This is what I’m looking for, soon dad will retire and making cat furniture and scratch post is what I recommend for his as hobby.


We made a few tunnels out of cardboard boxes which they love, so I’m sure they will love the new condos we plan to build them.
To create a sturdy, self-supporting target frame, all you need are some 2x4s, 1x2x48 furring strips, plus fasteners. I’d try to fly most of my creations as gliders, throwing them off of hillsides with a cobbled together radio system for rudder and elevator control.
Four sheets of balsa for a fuselage and a little more sheeting to make a tail, and I had my next chance at getting something substantial to stay in the air for more than a few seconds.
But every now and then, I find myself recollecting what a great time of discovery those years were. But I was excited by the prospect of trying something new that, as far as I knew, hadn’t been done on such a scale. I also designed it with its cardboard covering in mind, using flat surfaces wherever I could. With the wingspan exceeding 12.5 feet, I allowed the fuselage and wings to enjoy a fairly stout build at the cost of a few extra pounds. I decided that my servos and their applications would not require a PowerBox—another big cost reducer. So they were all ganged; throttle linkages were built and adjusted to be as identical as possible, from one engine to the next. The glow plugs’ high current draw at such a low voltage can easily be compromised by tiny amounts of resistance—even fractions of an ohm. This allowed me, for example, to prime engine 4 (for starting) with wide open throttle, while keeping the other three running engines from screaming away.Instead, I’d have them running at idle with the power shut off to those throttle servos until all engines were started.
I decided that it was realistically safer to have this system in place based on observations at the field through the years. Before I was finished, the main gear went through a second revision and the third undercarriage design did a better job of distributing the weight between the nose and main wheels, which was the result of having located all four main wheels to one axle.
That’s relatively light hardware, but the majority of the Condor’s weight was in the wings. Basically, the model needed to establish a good, fast taxi of which I had complete directional control, before opening up the engines all the way. Not as much throttle as I anticipated was needed for the Condor to roll over the grass under its own power.
Luckily I resisted and went through my checks, including visualizing the climbout I wanted.
Having watched the video, in reality the Condor took less than five seconds to go from a standstill to airborne. It was “corrugated overcast.” After flying around a bit and quickly gaining a feel for the model, I did one slow pass over the runway and saw that I could expect a fair amount of flying stability on the landing approach. The model flew directly down to the runway, set its 7-inch wheels on the grass, and lumbered to a stop with four running engines.
However, the relatively low wing loading for such a large airplane helped me get to an approach and landing each time. However, I noticed no adverse yaw in the air from uneven engine thrust that might have existed. I like the concept that one engine is unable to taxi a fourengine model on grass, but two should be capable. Build a cat tree today because if your cat doesn’t use it you can lure him up by putting your plants on it! Today I’m going to step on some toes and outline loose differences between Cat Condos, Cat Trees and Cat Condos. Your site is excellent, it is great that you shared your hard work and that the original builders shared their secrets too.
God gave us our pets to love and be loved by them in return, and giving them a safe , comfortable place to live and play is a pleasure we should enjoy as much as they will. I have 4 cats and since they are no longer allowed outside (coyotes), we needed something to entertain them and keep them from wanting to go outside.


The target holder, which supports an 18×24 inch cardboard target backer, separates from the base for easy transport. So the thought of employing some type of cardboard in building a model had been playing in the back of my mind for years.
I never had a multiengine model, but throughout the years I had become comfortable and confident in operating my engines to the point where it didn’t seem to be an unwise leap. 61FX engines at 23.6 ounces each, and approximately 80 square feet of cardboard, which weighed roughly 10 pounds.
I merely doubled the thickness for use with the ribs and tripled it for use with the firewalls. It was time to see if my four .61s could actually pull an excess of 50 pounds into the sky.
Each of those times an engine stopped, I was in a position to immediately bring the running engines back to idle. I could hear a couple of engines running slightly slower than others in their midrange and wanted to improve the synchronization as a matter of good practice. It seems like a good heck on engine selection to me, although there are many other factors. My definition is that I want a “tree” as in talll-or I will soon be pulling kitty off the top of my 10 foot drapes! Get-go with a design idea antiophthalmic factor vision of what you wishing your cardboard introduction to look But consider this commencement it doesn’t have to be vitamin A sauceboat at completely It. The fact that everything I tried to fly usually crashed immediately after the hand launch didn’t stop me from trying again and again.
Tossing on 6 pounds here and 10 pounds there was unfamiliar territory for me in building RC airplanes.
The aircraft heaved itself off of the ground and, with little complaint, answered my respectful request for a shallow climbout.
I haven’t noticed issues with the cardboard’s stability in the days I’ve had it out in temperatures n the mid- 80s with medium-high humidity.
Since he is an only child, I don’t need much room–just a ledge or two, a hiddy hole condo & scratching posts. Model to fix how many sheets of cardboard you’ll The Phoenix Zoo team designed their successful cardboard boat designs.
The servos are located in the tail; thus one had only to attach the servo connectors upon assembly.
The elevator was sensitive and I had to correct the steeper banks with some opposite aileron, but I was in business. On landing, the wingspan’s long reach doesn’t threaten to drag a wingtip, even with a healthy correctional bank while touching down.
It really helps that the builders said how long it took them to build because I don’t want kitty to be one year old before it is finished. I estimated that the design could absorb this extra weight and still keep the wing loading within an acceptable range. One of the inboard engines at full throttle would not move the Condor, even if I helped start it rolling. I built two unique features into the access hatch in the nose to add convenience in operating the four engines, the first of which is a master remote glow plug connection that supplies power to all four glow plugs through four toggle switches.
The relatively large vertical surface might give the Condor additional relief from the ill effects of uneven engine speeds.
