How I make "In-Motion" propellers.........

Hi all,

There were some who asked me to illuistrate the method I used to make the propeller appear to be turning on the Cessna 172M “Speed Blur” diorama I posted last week… so here it is:

The illustration pretty much tells it like it is; if there’s any questions or clarifications required, just ask.

Thanks for lettering me share… [:)]

Well thought out and nicely presented. That’s a keeper! [tup]

Very nice! I can see myself trying this one.

Frank?
How do you think this would work/look on a 1/35 helo?
I have been trying to come up with a way to do just this for diorama purposes.

Thanks Mojo, Hannaman, and Randie! [:)]

Randie: Hmmm… interesting question! I was thinking about doing it on the 1/144 Chinook conversion… will use the picture below as a guide.

The biggest thing I’d worry about in applying this to a larger scale build, is the clear extensions warping over time… I’ve also thought about how this could be minimized by sanding the top of each rotor blade flat and trimming it into a point, so the clear piece will fit on top of each blade stub. The clear piece will be the same width at the blade root and emanate outward… where as the blade support underneath will get progressively narrower and thinner.

If you look at a picture of rotors turning, you can see how the fuzzy black inner blade meshes into the wider, nearly transparent outer blade. Since the bottoms of most rotors are black, after using filler and sanding along the border of the lower blade support, blended into the clear piece with the airbrush, it should eliminate any warping worries without affecting the appearance. (it may even make it better looking, since the inner blade will have thickness.

Either that, or… no, now that I think about it, that would probably be the way to go. If it was a smaller scale, the entire blade could be duplicated using a clear piece, with maybe a piece of piano wire underneath for support, but I think the above method would be better suited for a 35th scale helicopter.

That would make a good side-line project, you know, building a single rotor and see how it turns out. [;)]

Take care,
Frank

Great idea. I have purchased several kits from EBAY that have been had broken or
missing propellers. BTW dont buy ebay kits when seller makes following statements
sold as is
I know nothing about kits
may be missing parts
gotten from an estate sale
found in an old New England country store
Of 112 kits I purchased about ten percent where missing canopys,decals, prop
The best thing is dont buy a kit unless the seller states that in is in a factory sealed box

Another thought, Frank.
In 1/35, couldn’t you use a little thicker clear material than what you are using on the 1/48 stuff? After all, the blades WOULD be a little thicker.
Just a thought.
I just may give it a try. I’ve got a “Charlie” model Huey I’m going to backdate to a “Bravo” model with Cobra Co.'s backdate set. Sooooooooooooo, I’ll have an extra rotor to play with. Plus you would have to do the tail rotor also but, being of smaller diameter, you could probably do it just like the 1/48.
