Centuri UFO sighting
2 Attachment(s)
This is a cardstock / downscale combined model.

The Centuri Alien Scoutship Flying Saucer has always been one of my favorite kits. I had a couple when they came out years ago. The design to me was so well thought-out. Centuri gave us the basic flying saucer that most flying saucers have been designed on since.

So I set out to clone the Centuri UFO. I know, others have done this. I decided to take a different approach to my clone.

First, I decided to draw the elements that had originally been embossed.
Second, I down-sized the scale to fit on a 8.50 X 11.00 sheet of card stock for printing.
Third, I wanted to share this design with anyone who would like to build their own.
At the end of this build thread I will send the PDFs to Scott so he can post them for sharing. It's all right with me if anyone wants to recolor or add their own touch to the drawing. All I ask is share it here.

The size of the craft is around 75% the size of the original Centuri UFO. ( 7 inch in diameter)

I used the BT-20 engine tube. If you want to fly on a smaller engine use an adapter.
Some parts are printed on 110 cardstock, and some parts are printed on adhesive-backed shipping label paper as noted in the thread.

Here are a couple shots of my UFO sighting.

Cool. Looking forward to it. I just finished painting my original and I'm trying to decide if the original decals would survive application.

I don't know why, but I hate doing the engine holder. So I'll do it first.

Take a piece of BT-20 tube cut it 2 3/4 inches long. Put the tube on the engine marking guide, and mark the tube with the appropriate letter for each line. Make the lines the full length of the tube. Label the lines C or L on the tube.

On label paper print out the L and C brackets. I used a cereal box cardboard to attach the L and C brackets to. On the back of the cereal box with the writing on it I put two layers of label paper to cover it up.

Now cut out the brackets.

Locate the engine lock, thrust ring, and mylar lock ring. Cut a slit 1/8 inch in the engine tube 1/4 inch down from the top. Place one end of the engine lock in the 1/8 slit. Slide the mylar ring over the engine lock and about half way down the tube to hold the engine lock. Check to make sure the mylar ring is not in the way of gluing the C braces in place. If it's ok, glue the mylar ring in place.

Glue in the thrust ring.

After the glue has set up on the engine tube, the C brackets can be attached to the engine tube. Make sure the C brackets are properly spaced apart.

Awesome! I've got an original in excellent condition that is too rare for me to fly so I've wanted to clone it for some time. I've never got around to it with all the other things going on in life, not to mention the mile long build cue I already have. I've thought about upscaling and downscaling, but unlike you, I've never gone past printing a few templates or gone past a mental exercise of how I wanted to show detail. I'm looking forward to your progress! :cool:

Thanks for the kind words friends.

This is not a hard clone to build. The hardest part is when you get to putting the sub-assembles together. You have to do some sanding, and a little fine cutting to get the L and C braces to fit inside the saucer. The nice thing is if you mess something up you just print the pieces out again and start again.

Got a full day tomorrow. Well try to get a couple post up then.

This looks pretty cool.
I'm not a fan of of saucers, but I am of Centuri.
I'd be interested in the plans to print to give it a try.
Feel free to email me the file when you have time.
Happy Thanksgiving!

Really cool so far - looking forward to your build.

The first thing to do is print out the page with the Core Tube Halves on it on 110 cardstock.
Find the two Core Tube Halves cut them out with an X-Acto knife or scissors.
Join the two halves together and let the glue set up. When the glue is dry, with the printed sides up, pull the two ends together and glue these ends together to form a tube. (Make sure the printed sides are facing the inside of the tube.)

You got that right. I cloned a full size UFO last year and noticed that if you tried to build it according to the Centuri instructions you would run into misfitting sub-assemblies.

I also downscaled the UFO to use a bunch of A10-PT motors I have lying around. The printed cardstock is waiting on the build pile.
