Description The Cyclone is a lightweight quad that uses a propeller drive. This system was rarely used in pre-Schism societies as it was louder and more dangerous than those using powered wheels. These drawbacks matter less outside larger settlements, where roads are less congested (or empty) and laws are less restrictive (if they are enforced at all). The Cyclone’s main advantages stem from its simplicity, and even its less positive traits give it a certain niche appeal.

Design Features

- The Cyclone’s simple tube-metal frame is extremely light but strong. A front fairing is usually fitted to decrease wind resistance and offer the occupants some protection from the elements. Heavy clothes provide the rest, though longer, looser-fitting garb is not worn for obvious reasons.

- The rear-mounted engine spins a four-bladed pusher prop, eliminating the need for a camshaft, differential, clutch and gears. The engine is tilted slightly to improve ground clearance and increase road pressure at high speeds. Some Cyclones have safety cages, but most have simpler rings or bars.

- The wider rear axle and heavier tyres help support the engine’s weight and increase stability. Vehicles with powered wheels usually accelerate faster and can turn more rapidly, but Cyclones are well suited to long journeys at high speeds.

- Some Cyclones use multi-pitch propellers as a substitute for gears. A coarse pitch is used for acceleration and a fine pitch saves fuel while cruising. Reverse pitch lets the Cyclone move backwards or decelerate more rapidly. Cyclones can usually stop before vehicles with normal brakes, especially on slippery roads.

- Cyclones are less popular in crowded environments; besides the obvious danger the propeller blades pose in a crash, their strong backdraughts can cause problems for light vehicles and foot traffic. The raised engine and propeller noise restrict rear visibility and hearing. Most Cyclone drivers expect other travellers to notice them first and stay out of their way!

i like the big fan on the back does it give the vehicle extra speed? :3

Looks good but it wouldn't be that popular in a dystopian world either. It's just inefficient!

Thanks! The designs we saw in Fury Road would be pretty hard to top!

You know i ca see someone knocking together one of these for fun


adding a rudder behind the props wuld give it some interesting handling options... as long as the driver didn't manage to put it into  skid.

Thanks for the link! I'd say the Shrike's a better design - the enclosed cab would be a real asset on a larger vehicle, and the vertical spoilers would protect the prop and might also improve its efficiency!

A system like this would have this sort of tagline:
"Great speed and mileage. Sucky torque."

I mean for a buggy platform it doesn't really ahve any of what buggys are actually good for, which is offroad power.

Or is this salvaged from a buggy?

jflaxman In reply to Internet-Cancer [2014-02-12 14:32:55 +0000 UTC]

You're right. I used a buggy as a starting point not to suggest a similar role but because it's a simple, strong and stable base for the radial/prop engine. I mentioned some drawbacks in the description (normal dune buggies would definitely accelerate and turn faster) and in a longer one I could cover salvage (the radial engines could be sourced from older, no longer flyable planes).

Acceleration might be improved through applying maximum power on neutral prop pitch, then applying pitch for a quick start. I've seen this technique used on planes, but powered wheels would still deliver better results.

A wider wheel base would be quite a good thing to have with a wide wheel base like this, actually.

I like the idea of being able to change the pitch of the prop. That offers a whole new level of control for the driver, actually. A prop, I imagine, would create an imbalance in tire grip and relative weight and thrust.

The British Air Force, at one time, had an armored car like this.

That wouldn't be this by any chance? www.google.com.au/search?q=pro…

I can't see many benefits - it would be too noisy to be a good scout and the prop would limit fire arcs. Maintenance would be easier, especially if the mechanics were used to servicing planes. It's still a great example of the strange ideas being tried at the time!

CanRay In reply to jflaxman [2014-02-12 19:46:33 +0000 UTC]

That would be it.  They built it because the air force was down pretty far for armored cars, and they needed something to go out and rescue downed pilots more than anything else.  It was designed by an airframe builder (which is why a lot of the designs are "Airplane-like"), and used the same engine as the biplanes.

It wasn't well liked.

Awesome! I built a model of a similar vehicle, I'll try to post it soon.

Hmm, this vehicles reminds me a little bit of the buggy from Doomsday, with the propeller that is.


Awesome work on this, I love it!


How fast do you think it would go? I'm curious.


Keep it up man! ^_^

Speed would depend on all kinds of things, but the "rail zeppelin" which also used a pusher prop en.wikipedia.org/wiki/Schienen… still holds a speed record for petrol powered trains. Many prop cars have been built but most seem pretty amateurish and I haven't improved on this here.

A couple of old French designs had the propeller at the front, which would have combined worse visibility with increased lethality!

I'll have to look up Doomsday now, it sounds like a promising lead.

Wow, that thing looks scary! 143? wow, that is fast.

Hmm interesting.


Wow, that sounds extremely deadly, and would be fun to watch~ 

game wise of course~


Its a great movie, I watched it twice! You'll love it
