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

Creator: James Joyce | 2003-06-01

Publisher: McFarland & Company Incorporated Pub

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.

Flying Insects and Robots

A notable example is the quadrotor, which uses four rotors in a cross configuration.

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.

    Perfect after mods and huey body

    Customer Video Review Length:: 4:07 Minsthis is one great helo I paid $86 bucks for mine including shipping over at banggood, but the mods are a huge help, heat sinks, lipo battery, canopy mod, landing skid rubber nuts, this bird is not easy to fly should have some flying behind you before trying, that said, I love how this handles, smooth, hovers great, great head speed even into wind, love that you can control the percentage of use on your sticks I like 85%, default is 90%, makes much more easy to fly, no dual rates on the remote but at this price that be asking too much this computer really tried to go towards the hobby end grade on this helo, once I completed my mods it fly's just as good as my $159 Walkera V200D02 and better than any Eflite Blade, so if your into the market for a good 4 channel but the hobby grades at over $150 is to pricey and the lower grade double horse not enough power this is the bird, watch my video I posted here, that was my very 1st flight and after the mods were all... 5/5 Dan (aka THXkid) (Phoenix, Az United States) - See all my reviews = Durability:, August 27, 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

    A great helicopter!

    0 5/5 Maik - See all my reviews This review is from: JOGOTO Thunderbird X8 Serie Large Alloy 28 Inch 2.4G 4CH RC Single-Blade Remote Control Helicopter with Gyro (Color May Vary) (Toy) I have always loved little electronic vehicles like planes and helicopters, but this one is not your ordinary remote controlled helicopter. The gyro on this thing one crazy awesome electronic device. I know we have all bought those toy store or mall kiosk ones and were disappointed, but I was not disappointed with this one. I recommend purchasing this if you want to have fun with something that will actually last. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , February 22, 2015

This review is from: Neewer® 4CH 2.4GHz Single Blade / Propeller RC Remote Radio Control V911 Helicopter BNF with Gyro (Blue/White) (Toy) After MUCH use my first V911 gave up the ghost. (I smashed the tail rotor into a sconce in the house & although I found a replacement rotor I don't have a solder gun to attach the wiring). This one was a perfect replacement, and of course I can use my older one for parts if I ever need them (although these little guys are tough & survive 100's of crashes without problem so long as you cut power). 0 Help other customers find the most helpful reviews  Was this review helpful to you? , September 16, 2013
