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.

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.

    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 Syma S107/S107G R/C Helicopter - Red 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 flight). Sometimes if you get if off the ground to about 3 to 5 feet you may notice the erratic behavior disappear (which may be due to "ground... 5/5 ppmd "Professional" (Arizona, USA) - See all my reviews = Durability:, February 11, 2012

    It's not tough enough.

    Training gear is for people just learning to fly RC helicopters. It's expected for beginner's to land hard, especially when you get nervous and slam the throttle/pitch down when losing control. The plastic hub will break with a mild landing. I didn't crash nor did I have a hard landing. The heli came down at a slight angle and two of the balls made contact with the ground first and the hub broke. I made my own training gear using a piece of 2" x 2" x 5/8" piece of hardwood for the hub and 5/16" dowels for the rods. I reused the balls that came in this kit. I quickly ran a 5/16 drill through the balls and they fitted securely on the ends of the dowels. It works great and I've since had some extremely hard landings, but the wooden training gear doesn't break. I paid just over $3.00 for this gear, so in my opinion, the balls are worth it. It beats having to buy plastic balls and drilling/mounting them to the ends of the dowels. That's why I give it 3 stars... 3/5 Mark M - See all my reviews Verified Purchase(What's this?)

This review is from: US Ship Rc Helicopter Training Gear for Trex 450 and Clone, Blade 400, 450 Helis I thought this would work for a T-Rex 500. I've fitted it and it does work as far as providing stability on landing where a possible roll-over, or mild nose up or down occurs. User beware that I believe it's marginal for a T-Rex 500. However, you can salvage the plastic balls and attach them to longer and heavier weight spring steel push rod stock and use standard tie strips to secure them if you want to use them with a larger aircraft. I'd like to see the supplier provide a set for a T-Rex 500, and also be a little more specific in their advertisement. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , February 5, 2015

    The right size, the right price

    I like the size (14 inches from nose to center of tail rotor, 16" rotor span) and the "whoosh" of the wide blades. 10 below zero this morning, but I took off inside from the hard floor. After pushing it past the air bubble near the floor it was controllable and I was able to trim it while keeping my eyes on it. The hard left skid on the floor when taking off is scary, but it flies! The transmitter works very well, with three stages of control sensitivity and a knob to turn the throttle down from 100%.I have a Syma F3 that I've had in tree branches, bounced on the driveway, slid off the roof and it's still going strong - same blades and everything.

So I wanted a mid size chopper. It was tough to decide between V912 and DH 9116, I picked this one because I have the F45 and am very happy with it. There was no choice of color but I hoped for the blue one, And when I opened the box my wife said my eyes lit up like a Christmas tree. And man what a beautiful Blue Helicopter. Out of the box it flue way to much to the left, but after a few adjustments on the swash plate and servo rods, this bird is AWESOM. It hovers 2 feet off the floor dead vertical in about a 6 foot square area in the center of my living room. Then I took it up to about 6 feet above the furniture and flue it at a nice pace around the room that's about 15 x 15.
