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

Creator: James Joyce | 2003-06-01

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 ...

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.

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.

    I was hopeful but that faded rather quick

    Let me first say I am a big fan of WLToys Helicopter products. I own multiple V911s and v922s. Past positive experiences led me to making the purchase of the V912 Helicopter. While my v911s are very fun I was looking to go to a larger heli just to scratch an itch. Because I have had great experiences with both the v911 and v922 I expected the same from the v912. Below are my thought of the heli and then the reason for 3 stars and a return product.Unboxing: Out of the box I was like a kid on Christmas (I'm 30 but still a big kid). The helicopter looks fantastic. The body is very similar to the v911, but feels and looks so much stronger due to all of the metal parts. Although I was aware of the dimensions of the helicopter when I ordered it, seeing it in person my first thoughts were "wow this is big". The physical build quality is great and I have no doubts that the heli could take some punishment in the event a harder crash should happen.

    Requires a bit of fine tuning...but a good start

    For a first helicopter, I'd not suggest this..but rather, go with the V911. After you learn the basics of flying and crashing, you can move up to this flying bus. At about 16 inches long, you can really get some speed up but it's hard to stop on a dime like the V911 could.Overall you need to fine tune the product from the box. Level your swashplate by eye and then you're set to bind and fly. The stock battery gives you about 9 minutes flight time, but be sure to set a timer for 7 or 8 to give you time to land!I suggest going to HobbyKing and getting their "Hobbyking 2-8S Cell Checker with Low Voltage Alarm" Set it to 3.4 or so and do some testing at lower levels to see where you get after the alarm sounds. For me 3.3 is too low and only gives me about 30 seconds landing time.The unit needs to be balanced a bit but will fly none the less. There are plenty of prop balancers you can get at hobby or online shops. I'd suggest you get them... 5/5 Dave "Sonic" - See all my reviews Verified Purchase(What's this?)

    Worth every penny...Most AWESOME!

    Customer Video Review Length:: 1:42 MinsLet me say, this is easily the most awesome thing I have ever owned. I received this helicopter as a 30th birthday present and my childhood dreams of becoming a helicopter pilot were once again restored! :) This thing looks, sounds, and maneuvers just like a real helicopter. The sound this thing makes alone was enough to impress me (a bit intimidating actually) and we had a blast chasing the cat around the yard with the heli :). It is quite agile for its size (this thing is large) but you have to remember you are moving more mass. So if you are in an aggressive forward flight, give some time and space to slow back down. Also, you want to make sure to give yourself plenty of open space. This thing is no toy and could easily hurt someone if the blades come in contact with skin (especially neck height..ouch). The box says 14years and up and I would definitely recommend you stick with that.With all of that positive stuff I will say, like... 4/5 E. Ridenour - See all my reviews, August 21, 2013

    Don't waste your money on the double horse, get this one first.

    This is the funnest helicopter I have bought on Amazon so far. I started with the small Syma S107, which I still play with indoors, I tried the larger double horse, both the 9118 Co-axial and the 9104 single rotor, The 9118 was easy to control but was very slow, the 9104 was very hard to control but was a little faster. The F45 blows both of them out of the water! Having 4 channels allows you to correct any side to side drift when taking off so its was more controllable that the 3 channels. I am sorry I wasted so much money trying out those other ones, but you live and you learn. The controller for this one is awesome too! It has an LCD with different control modes and the option to change the throttle lever from the right or left side. An added bonus is that this controller only used 4 AA batteries! If you've played with the cheaper heli's you are probably used to needing 6 to 8 batteries, but I guess this is a better quality controller so it doesn't need as much power.

This review is from: Toys Agency MJX F645 F45 4ch LCD 2.4GHZ Large Single Blade Rc Helicopter - Color GREEN (Toy) Nice mid size heli. Charged it up and away we went. Very minor trim tuning out of the box and it flies great. Probably flown it about 15 or 16 times. I've ordered up spare batteries and a few spare parts so I can fly it more than once every 3 hours. It really handles well and is reasonably responsive. Careful in a slight breeze because it can get away from ya. Considering buying another one. Highly recommend for someone wanting to fly outdoors and is stepping up from smaller helis. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , May 9, 2013

    Tons of fun

    This is my 4th heli, the first 2 were the micros you would see flying around the mall a few years back. They were fun but lacked control. After a couple weeks, I was bored and decided to order a Blade CX2. It was much more manueverable and gave me a run for my money skill wise. I didnt have enough room in the house to have much fun with it so it didnt get used a whole lot. A few weeks ago, I got the itch to try another heli out and figured the very small size would allow for more enjoyment in the limited space I have available. After a bit of research, I settled on the 9958 because it could bind to the Turnigy 9x transmitter that I'd already ordered and it had some decent reviews from other sources. I also wanted to stay away from the coax helis and try something a bit more difficult to fly but not too tough.After charging it up Christmas morning, I set out to test my skills. It was tougher to fly than the CX2 but not too much. It was considerably quicker, too quick for me... 4/5 Aaron M. Weigand - See all my reviews, December 28, 2011

    So much faster than the V911

    Customer Video Review Length:: 3:05 Minsupdate 4/26 bought 2 more of the GW 9958 one came flying perfect as the video from this review shows and you can see the 1080p version of it over at youtube, I have the blade MSR paddle flybar coming in this weekend suppose to just a drop replacement, will see.took a stab and got this when nitroplanes has it on sale for $30.00, as I already own a V911 4 channel single blade micro I knew how to fly these, but wow this thing is twice as fast as the V911, while the V911 is rock stable and hovers hands free inside and outside, the 9958 is strictly an outside side bird and while it tends to have a strange TBE when hovering, dont even try it inside, maybe in a area the size of a 2 call garage. its ok for hover stability, but outside just fly it and be amazed, very fast, tight turns, tends to favor left turns over right, which is just the opposite of the V911.

    Better outdoors than indoors

    I own 2 107g and a 108g. This one is a lot different. The helicopter has tons of speed and doesn't hover particularly well. I broke a piece on one of the main blades the first day, but it came with a couple extras, so that was a quick fix. After a ton of crashes, I took it outside. It really seems better suited for outdoors. Fly it in a field rather than a parking lot while learning. It really zips around and is well worth the money. Probably not much of a better helicopter out there for $50. I've read the V911 is comparable and more stable inside than this one, but can't zip around as fast outside. That's ok....I'll stick to my Syma's inside and use this one outdoors. Found some really cheap batteries and usb cables at miracle mart.....bought 4 of each there, and I'm gonna pair them up with a 5 hub usb charger I bought from ebay for $5. This should give me flight time 30-40 minutes straight after I have them all charged up. Overall, highly recommended.
