Wil Holy crap. If it even leaves the ground he must be a genius. So you've told us what you think of ultralights. What do you think of homebuilt helicopters? I flew a Breezy once and I can tell you it felt REAL strange sitting up there in a dining room chair with the wind blowing up my butt. It was kind of an "unusual" sensation to say the least. I got a ride in one. Sorry, on one. The owner made me sit in the front. And then he did a big steeply turning dive! Dudley, Bertie... it's more fun sitting in the front seat during a stall and recovery! The sky just drops away and you have the whole world in front of you. I did a few stalls before I landed the Breezy. I always do that with a strange airplane just to get the feel of it near the left side of the envelope. You're right, it WAS a STRANGE feeling :-)))) -- Dudley Henriques |

wrote in message ... OK. Maybe you are right. Some of us will have to arrange a trip to Nigeria to verify it. You go ahead, I can't afford it. Not worth my time. The burden of proof for a claim like this is on the person making the claim, not the person reading about the claim. How hard can it be for Muhammed to have a friend take a picture of the contraption in flight? Not as hard as making it fly, I presume. So where is this evidence that it is a hoax? Lack of credulity on my part: 1) Failure to show the aircraft in flight. 2) No valid source exists for the news as reported by the blogs. The "Yahoo" link is bogus. The "raw feed" link is merely another blog. 3) The craft looks like it can't fly for various reasons. 4) It was built from junk in 8 months of spare time. He found all these parts in a junk yard and made them work together for controlled helicopter flight in eight months -- but only in his SPARE TIME. Hmm. Must have a lot of that spare time and some damned fine junk yards at his disposal. 5) No machining required. Apparently he didn't have to machine ANYTHING for a completely custom, one-off vehicle. Or does he have lathes and other machine tooling stuff at his ready disposal? Welders, sheet metal manipulating equipment, digital equipment and interfaces to make the "joystick" work as a controller. That stuff takes time. More time than 8 months of spare time. And you know, he's never done anything like this before! This would be an amazing, and very unlikely, job to pull off ANYWHERE in the world. Lets see this logic. If a report is from the western world it is assumed true (innocent until proven guilty). If a report is from Nigeria (and some other places) than it is assumed to be a hoax (guilty, of anything we want to assume, until proven innocent). It has nothing to do with location in my opinion. If that contraption were in my neighbor's backyard here in "the western world" and he said, "hey, it flies. It flies up to 7 feet in the air," I'd say "great, let's see it." It has to do with lack of evidence that flight was ever performed in the unique device pictured in a single picture only SITTING FIRMLY ON THE GROUND. The burden is not on me to prove that it can fly or that it can't. It's at least possible I think, so, let's see it. Is it too much to ask to see more pictures before you believe a story like this? More food for thought. Am I the only one that can't see a tail rotor on the tail boom? Also, the main rotor shaft appears to be about 1" in diameter, with little if any outboard bearing near the hub, perhaps even a universal joint. Could this really be successful at harnessing 133 hp, at 400 rpm or so? I have serious doubts as well. Here is a couple more photos but still not much help. http://www.afrigadget.com/2007/10/22...ains-by-storm/ |

I see what appears to be a two-blade tail rotor in approximately a vertical orientation with top blade black and the bottom one silver. Try saving the photograph on your computer and enlarging by spinning the wheel on your mouse in MS Photo and Fax viewer, or enhance it with Photoshop. |

And here is a statement from the same link page:
Although some government officials got very excited when they saw him conduct a demonstration flight in neighbouring Katsina state, Nigeria's Civil Aviation Authority (NCAA) has so far shown no interest in his aircraft. |

Here are a few more pictures of the guy.http://afp.google.com/article/ALeqM5...7tMmr2zeQmiRig From the photos its amazing simplicity - he's got a front-wheel car driveshaft running the rotor and implementing rotor tilt. Hey if he only gets it off the ground thats flying. Don't forget helicopter ground effect, valid for height of one rotor length. Thats probably where he could get the 7? feet. Less power needed to hover near ground. |

Less power needed to hover near ground. He could still have a tether at up to 10 feet negating the need for a tail rotor until it's ready for solo flight. Tony |

Mortimer Schnerd, RN wrote North American Aviation took the P-51 from doodles on a napkin to lifting off the tarmac in 117 days. Mortimer...Do you know what the "Tarmac" is? From Wikipedia: snip While the specific Tarmac pavement is not common in some countries today, many people use the word to refer to generic paved areas at airports, especially the airport ramp or "apron", near the terminals despite the fact that many of these areas are in fact made of concrete. This term seems to have been popularized when it became part of the news lexicon following live coverage of the Entebbe hijacking in 1976, where "Tarmac" was frequently used by the on-scene BBC reporter in describing the hijack scene. The Wick Airport at Wick in Caithness, Scotland is one of the few airports that still has a real Tarmac runway. It was in the lexicon long befor 76. I was taught it in the USAFSS (intelligence service) back in 54 when I was studying Russian. Harry K |
