I mean, seriously, how do you physically construct a crankcase to support a 2 cycle V8? Either that or the crank does not share a pin between opposing cylinders and they are firing together, but that sounds pretty dumb. I tried to find a pic using Google-sensei but all I found was this https://www.miataturbo.net/attachmen...ine=1421248969 |
The intake manifold should be where you'd expect an oil pan to reside.
Holy shit this is awesome: http://airpigz.com/storage/2013/july...=1373370176576 http://airpigz.com/storage/2013/july...=1373371193526 http://airpigz.com/storage/2013/july...=1373371843271 |

1: Some guy built that in his garage. It clearly has a significant payload-carrying capacity. 2: Lots of people now have access to remotely operated drones with return video feeds. 3: While most such aircraft noted in (2) above are limited in range and duration by the power of their radio transceivers and the capacity of their batteries, an aircraft as noted in (1) above would be capable of carrying powerful radio equipment and large fuel stores. Within reason, its range would be limited only by line-of-sight over the horizon, and even that could be overcome by the placement of the base station in a mobile platform, such as the back of a minivan. With minimal coordination, control could even be passed between multiple base stations en-route. 4: There are people in this world who wish to cause harm to the general populace and sow terror and chaos for a variety of political and social purposes. In general, they are limited by technical means. 5: I see no actual reason why the people noted in (4) above could not take advantage of points 1-3, to create a land-guided cruise missile capable of delivering a very large conventional explosive payload to venues such as the Superbowl, the new-years-eve festivities at Times Square, the World Cup, an Olympic stadium, etc. Casualties would be massive.

Joe: what if I told you that for the princely sum of $300 you could buy all the hardware to automate flight control and waypoint following via GPS?

$300? Thats big ballin'. Gotta get those Chinese clones
433Mhz ArduFlyer2.5.2 LEA-6H UAV System with Annunciator https://www.miataturbo.net/attachmen...ine=1421254162 I still dont have GPS on any of my setups. No excuse, just being cheap and stupid. As for putting your FPV "ground station" in a vehicle. Im pretty sure that is how they pulled off this little stunt. either that or they have some mountain penetrating radio setup |

https://www.miataturbo.net/attachmen...ine=1421254185 It's entirely possible (and cheap) to construct a semi-autonomous aircraft and fly it (almost) around the world using satellite based navigation and commands. Just provide a destination and optional waypoints, it will go there. Those things can stay aloft for days. Mind boggling stuff. |

In theory, a radio-guided missile could be disrupted by directing large amounts of broad-spectrum RF noise at it, though of course you'd have to know it was there, and have a broad-spectrum RF generator conveniently lying around at that exact instant. As for GPS-guided solutions, I hadn't seriously considered that possibility as it seemed a lot more complex to build and operate reliably, but I'm not sure how you'd counter it.

There are 2 ways you could divert a GPS tracking system, either by jamming or overrunning the signal with your own fake GPS signal. Unless they have very smart GPS units, they won't know the difference and you can have it redirect wherever you want.
Radio jamming doesn't occur with broad spectrum noise as it takes too much power. Jammers are very smart and designed to disrupt certain signals. https://www.miataturbo.net/attachmen...ine=1421422735 Spectracom GSG 6 Series Multi-Channel Multi-Frequency GNSS Simulator, GPS, GLONASS, Galileo L1, L2, L2C, L5 GM20 Military Jammer Used Against Remotely Detonated Bombs |

Here are some comments from the second link above:
I am using this jammer for almost two months already. I've bought it on my son's advice. He said that it is the best tool when it comes to protection from all those IED's and terrorists. And I'm glad that while buying this device I support the same technology that saved my son's life a couple of times back there in Iraq. I was using similar devices during my service in Iraq. Those devices were much older still they saved my life along the missions when we were patrolling the area with my team. There are so many IED placed along the roads in Iraq you wouldn't believe! If not these jammers I would probably be dead already. So when I came back to USA I wanted to have such device beside me even in peaceful time. It served me the good turn there. And I found this jammer. It is even more advanced that those I remember from the army so I bought it without hesitations. I use it since then and it works just great. https://www.miataturbo.net/attachmen...1&d=1421423867 |
