Pucker Factor 10, Memoir of a U.S. Army Helicopter Pilot in Vietnam

Creator: James Joyce | 2003-06-01

About this book
The author was drawn into the Army through ROTC, and was trained to fly helicopters in combat over Vietnam. He flew both Huey "slicks" and Huey "gunships": the former on defense as he flew troops into battle, and the latter on offense as he took the battle to the enemy. Through this book, the author relives his experiences flying and fighting, with special attention given to the pilots' day-to-day lives - such as the prankish smoke bombing of Disneyland, the nickname for a United States Army-sponsored compound for prostitution. Some of the pilots Joyce served with survived the war and went on to have careers with commercial airlines, and many were killed.

About this book
Flying insects are intelligent micromachines capable of exquisite maneuvers in unpredictable environments. Understanding these systems advances our knowledge of flight control, sensor suites, and unsteady aerodynamics, which is of crucial interest to engineers developing intelligent flying robots or micro air vehicles (MAVs). The insights we gain when synthesizing bioinspired systems can in turn benefit the fields of neurophysiology, ethology and zoology by providing real-life tests of the proposed models.This book was written by biologists and engineers leading the research in this crossdisciplinary field. It examines all aspects of the mechanics, technology and intelligence of insects and insectoids. After introductory-level overviews of flight control in insects, dedicated chapters focus on the development of autonomous flying systems using biological principles to sense their surroundings and autonomously navigate. A significant part of the book is dedicated to the mechanics and control of flapping wings both in insects and artificial systems. Finally hybrid locomotion, energy harvesting and manufacturing of small flying robots are covered. A particular feature of the book is the depth on realization topics such as control engineering, electronics, mechanics, optics, robotics and manufacturing.This book will be of interest to academic and industrial researchers engaged with theory and engineering in the domains of aerial robotics, artificial intelligence, and entomology.

Sensing capabilities are oen poor: For small remotely controlled (RC) helicopters, sensing is limited because the on- board sensors must deal with a large amount of vibration caused by the helicopter blades rotating at about Hz, as well as higher frequency noise from the engine.

    This is my second one. I broke the first using a pipe to get it out of a tree. Why buy another? It is without a doubt the best rc video helicopter I have received here. I intend to buy several more so I can rotate them when I am out and about flying them. Keeping one charged while we fly the others....thats how much fun these are. Durable? You bet! Outdoor flying? Not the greatest if there are any winds aloft at all, but on a calm day, there is nothing better than flying this toy over and over and videotaping your exploits. I have flown up to about 30 meters, and could have gone higher, but the darned thing was hard to see. Incredibly stable, you will find yourself flying this helicopter through increasingly more difficult paths, as it is rock steady when it is calm out.BUY THIS! for the money, it is amazing.As with anything, there are pros and cons. I guess in keeping with the other comments, the cons of this helicopter is that flying outdoors is a challenge if there is any... 5/5 Dave Francis (Bellevue, WA, US) - See all my reviews = Durability:, December 1, 2012

    Nice all black, good quality camera, stable flight.

    I received this today and charge it right away for test flight. It is very solid, as nice looking as Syma brand S031G only a bit smaller. Charging time is 20-30 min, and flight time is 5-7 min quite short. If you can upgrade the battery to keep it longer in the air that would be more fun. The 2.4G transmitter is neat, it's not bulky and has an electronic display. Binding take some time, i don't know why, my transmitter sometime takes up to full 5 min for it to bind with the black bird. But once they both hooked up, it's fun to fly. Operating the camera/still photo is no brainer. There are one button for each action on the transmitter, on or off, however it take some time to get used to. The slot for the SSD is as easy to operate as in any p/s cameras, insert the card, soft push to eject it. Over all, it's nice. But with the price of $50+, it's a little expensive. The "party light" led display along the tail boom is just sicken me (my kids love it); and annoying as well making it look... 4/5 Kevin - See all my reviews = Durability:, June 26, 2012

    It's more than you're paying for

    Customer Video Review Length:: 4:41 MinsThis is my 3rd heli ever. I'm been slowly teaching myself to fly so I can shoot aerial video. I'm a videographer by trade. So, all my heli purchases are based off my end game, which is to fly a DSLR. The MJX F45, for me, is a solid step in that direction. I was easily able to mount a GoPro to the front and relocate the battery for stable, balanced flight. The F45 lifts the additional weight of the GoPro without the housing (slightly less than the stock battery) without problem. I can still easily control the heli, even in a slight breeze. I have been able to fly the F45 higher than I should given my skill level. I've learned a ton with this heli. It's my first 4ch and first single blade. I've crashed it an embarrassing about of times and it's bounced back with very little damage. It even survived a huge fall shown in the video, with a camera attached, and still took to the air afterward (although it now flies horribly and needs repair)... 5/5 Twelvizm "I have a doctorate in rockin' it" (Portland, Oregon) - See all my reviews = Durability:, November 26, 2012

    Eminently flyable!

    I decided to buy the MJX F645 4 channel helicopter after reading many positive reviews, including that of Dan (THX Kid). It was also on sale at a local retailer at a great price, and spare parts seem to be readily available as well. The radio is 2.4 GHz and has a longer range than the 27-40 MHz offerings. All plus points!My only prior experience was with 3 channel co-axials, and I don't have access to a simulator. I didn't even have training landing gear attached. I am also not a video gamer, and was never any good at them either (just mentioning all this to indicate that I have just average hand-eye coordination skills!)Yet I was able to take this helicopter off, fly and land safely. The remote has the option to select what the manufacturer calls "Mod 2", and I selected this, since it resembles 3 channel control setups, in which the left stick controls throttle, and the right stick controls elevator and rudder. Experienced pilots would select what the manufacturer calls "Mod 4"... 5/5 Lentar - See all my reviews = Durability:, October 1, 2012

    Great single rotor, four channel helicopter!!

    I purchased my Double Horse 9116 from a seller on Ebay. Got a great deal on it as well ($89.88- current price) with free shipping. I was very pleased with my experience from the Ebay seller.What's in the box?You will receive a very nice looking DH9116 4 channel electric helicopter measuring 19.5 inches in length if you stretch the main and tail rotors out front to back and measure tip to tip. It stands 5.5 inches tall if measured from the bottom of the skids to the top of the main rotor assembly. Main rotor length is 15 inches. The DH9116 is fully assembled and ready to fly (after it's charged). You will also receive a four channel, mode 2 radio with a high/low rate switch and four trim buttons. The radio also sports a lighted LCD screen that shows trim and stick positions as well as battery life. The menu button allows for stick reversing and set up for left or right handed flyers. You will also receive a wall charger, plug and manual.What is "Mode... 5/5 Kenneth Marcum "Harley Man" (Fort Wayne, IN. USA) - See all my reviews, December 30, 2011

    Big step up from the toy 3ch copters

    Someone already wrote a really nice review of this copter so I'll keep this fairly short. First and foremost, if you think you know how to fly helicopters from flying 3ch coaxial helicopters, you don't. Although they have provided you with some of the physics of rotary flight, they've also provided you with a huge comfort level in that they are able to hover continuously. Forget most of that with this one.A 4ch single rotor is getting the user closer to collective pitch flying will still providing a greater degree of safety via being able to hover for brief periods and with some input from the flyer. More challenging but a lot more fund when you've mastered it. This is a great beginner copter for someone who hopes to progress to 6ch CP and likes to fly outdoors. Most coaxials do very poorly in the wind, this does better. Still not great but able to be confidently flown in 5mph breezes.The copter itself is very well made IMO. Real hobbyists will... 5/5 tom4416 "bookie monster" (Virginia) - See all my reviews, January 18, 2012

    Love flying this heli! Great value.

    This was an upgrade from my strictly indoor dual-rotor helicopter. I had mastered the easy 3-channel Syma, and wanted to try a single rotor 4-channel. I have never flown any RC helicopters prior to the Syma, nor do I have any real-life aircraft piloting experience.Your experience may differ from mine, but thought I would share. I do not think the 9116 is an indoor helicopter, as it requires a lot of free open space to safely fly (without damaging the helicopter). It takes about 1.25 to 1.5 hours to fully charge the helicopter, and once you are used to flying this heli, it will be a LONG 1.5 hours to wait! It is slightly idiosyncratic at times, but "resets" easily when you turn off and turn on the helicopter (when it starts to act erratically after a full charge, at the beginning of your... 5/5 ppmd "Professional" (Arizona, USA) - See all my reviews = Durability:, February 11, 2012

    Great Quadcopter

    0 5/5 customer - See all my reviews Verified Purchase(What's this?) This review is from: Heli-Max RTF SLT 2.4GHZ 1Si Quadcopter with Camera (Toy) I have a Helimax 1SQ and using this Helimax 1SI was almost the same. the on difference that I like is the ease of use. I notice that even when I bump in to something it still maintains the direction you started with. it uses the same battery as the helimax 1SQ but be careful when installing the battery put the battery in first then connect the wire which push into the battery slot. So far my only issue is calibrating the go home feature which is just a matter of following the instructions in detail. if your new or an average flyer change the sensitivity to a range of 30-40. I'm set at 45 about 3-5 minutes of flying time on a full charge which take 30-45 minutes to charge 0 Help other customers find the most helpful reviews  Was this review helpful to you? , December 31, 2013

    Not Recommended

    0 1/5 Siffert (NM, USA) - See all my reviews This review is from: Heli-Max RTF SLT 2.4GHZ 1Si Quadcopter with Camera (Toy) While this high priced quad has some new tech on it, it suffers from a bunch of problems. For starters, the prop guards are poorly designed and break easily (unlike the Hubsan 107 prop guards). The props easily slide off. Using the Hubsan 107 props instead cured this problem (which makes one wonder why Hobbico did not use those-haha). The "return to home" feature does not always work along with the direction control feature as well. Reading on R/C forums some have been lost and missing in action (MIA) with failed "return to home". Also the motors on this 1Si seem quite under powered when climbing. Finally, trying finding parts for this and if you are lucky to find them in stock, see how high priced they are compared to other makes of quads. I will say that the camera is OK for video so long as the day is bright. For me, one is much better off buying say a Hubsan 107 model, at half the price of this one along with none of this one's problems. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , January 20, 2014
