About this book
Unmanned Aircraft Systems (UAS) have seen unprecedented levels of growth during the last decade in both military and civilian domains. It is anticipated that civilian applications will be dominant in the future, although there are still barriers to be overcome and technical challenges to be met. Integrating UAS into, for example, civilian space, navigation, autonomy, see-detect-and-avoid systems, smart designs, system integration, vision-based navigation and training, to name but a few areas, will be of prime importance in the near future.This special volume is the outcome of research presented at the International Symposium on Unmanned Aerial Vehicles, held in Orlando, Florida, USA, from June 23-25, 2008, and presents state-of-the-art findings on topics such as: UAS operations and integration into the national airspace system; UAS navigation and control; micro-, mini-, small UAVs; UAS simulation testbeds and frameworks; UAS research platforms and applications; UAS applications.This book aims at serving as a guide tool on UAS for engineers and practitioners, academics, government agencies and industry.Previously published in the Journal of Intelligent and Robotic Systems, 54 (1-3, 2009).

    Double your flying time with dual batteries

    I bought this battery to perform some experiments with increasing my flying time. This worked great. I now average about 15-16 minutes flying time, and that is just until is starts to get a little weak. I could easily go another couple of minutes, but I don't want to push the batteries that hard, and it's a lot more fun flying with charged batteries.This modification is safe and easy. This is because these cells use safety circuits to limit over discharge and over charge. There are a few precautions though:1. Use two batteries of equal age. This means a new battery in a new heli and a new replacement battery, or two new replacement batteries. Do not mix a new replacement battery with an old, worn out battery.2. Use two batteries of equal charge - preferably discharged. This is not critical, but it is better to start with two discharged batteries so they don't have any significant energy if you accidentally short something. Also, it just keeps... 5/5 R.

    buyer beware

    This seems to be a busted product. I've received 2 of them and neither works as expected. The vendor said they hadn't had any problems. Maybe I was just unlucky twice.Some of these batteries have a little tiny chip in them that is there to protect from over charging. Some of them don't. My original battery had the chip. The one I received from this purchase did NOT have that circuit.If you buy one of these and it doesn't have the chip, but your original battery did, chances are you will over charge the battery and ruin it.The reality is there are a lot of SYMA S107 knock offs out there. There is a ton of variance in the components that one can purchase online for them because they all come from whole-sale chinese markets.Do yourself a favor, do what I did as a result of this 'lesson learned', wire up an ultra-micro rc plane battery connector to your heli and buy a real charger and real batteries.Search this "syma s107 battery mod... 1/5 E.

    Great little toy

    Most of the other reviews have hit the major pros and cons with this, but there are still a few more that I can add. Hope they help in making your purchasing decisions!PRO:- Thanks to the gyro, very short learning curve. Remote has two joysticks. Left side only moves up/down and controls speed of the rotors, which controls how much lift they generate. Right joystick moves up/down (controlling forward/reverse) and left/right (makes heli spin). You can also moving the right stick diagonally to make various turns while moving forward or backwards (reverse "figure-8's" are always impressive).- Surprisingly large number of "mods" that can be done to a $30 heli. After experimenting, I have settled on two minor ones. First, I removed the spring from the left joystick in the controller. This lets me put the heli in a hover and let go of the remote ("look ma, no hands!"). I have also moved the landing gear forward in their mounts to push the center of... 4/5 RJ (NY, NY) - See all my reviews = Durability:, December 24, 2010

    An unsung hero of the indoor RC helis - The Syma S107 (7.5 inches long)

    RATING: After flying the 7.5 inch Syma S107 indoor heli for about 3 months now, I have to say that it is one of the most under-rated RC heli out there, hands down. Shop around. At about $30 online with taxes and stuff, this little trooper delivers the looks, detail, durability and performance of a much pricier heli. The Syma S107 has only 3-way controls but it competes surprisingly well with the likes of the Blade MCX2 which has 4-way controls and retails for about $150 off-line.PERFORMANCE: I find it more fun to fly the Syma S107 than the smoother and more mellifluous Blade MCX2. In this sense the Syma S107 hews to a less is more principle: i.e. it delivers more with less. But here is the irony of the whole situation: the Syma S107's ragged performance edge actually connects with you better than the ultra-smooth Blade MCX2. It's almost like the difference between stick shift and automatic transmission. The S107's controls just feel more tactile than those of the Blade... 5/5 C.

    Is there such a thing as a toy that's too perfect...?

    The Syma S107 is so easy to control that on my first flight I had it tour my whole apartment, zooming in and out of closets and never touching an obstacle until I deliberately landed it. If you've never flown a good RC heli before, you might need to practice a bit. It might be your second or third flight before you get that good.The S107 is *really* that easy to control.I'm sure that many of you have played with Air Hogs and other micro helis and you long for a little heli that just plain flies where you want it to fly and stays up in the air. I'm here to tell you that such perfection is within your grasp.Before I got my S107, I already owned two Syma S105s and I never get tired of flying them. They look almost identical to the S107 and the remote is identical, but they take a little bit of skill to fly with precision and I've made little tweaks here and there to get better control.The S107 takes almost no skill to fly. They gyro makes... 5/5 Hey Mo!! (The City of Townsville) - See all my reviews, July 28, 2010

    Best $22 Toy Ever Made!

    I'm a 47-year-old kid who has always loved aviation and RC models. Cars, planes, everything. I currently have two other small scale rc helicopters that I have enjoyed, but they are NOTHING like the Syma S107. Not even close. The thing is, they cost A LOT more.I see a lot of comments here about how easy this model is to break. The two channel models I have are much more likely to break because you have very little control. With the Syma S107, you have ABSOLUTE control. Have you ever seen a dragonfly in flight - stopping and turning on a dime? That's what this helicopter reminds me of.Right out of the box it is impressive. The quality of construction is beautiful to look at. If you've ever seen one of the huge rc helicopters that the pros fly, this looks like a scaled down version, with a metal frame and boom tubes just like the big ones. Two separate motors operate the main rotors independently. When you initiate a turn, one rotor spins faster than... 5/5 J. Leutgens "Jim in CHI" (Oak Park, IL) - See all my reviews, March 23, 2011

    Best Micro Heli for the price: Bar none

    I purchased the syma 107g for the specific purpose to do a product review. I fly and review R/C edf jets, fixed pitch, and collective pitch helis. I purchase everything myself and do the reviews specifically for the informative purposes of others. Having flown only the blade micro helis, I was skeptical as to how these would perform. Regardless of the other great reviews I was prepared to be underwhelmed by the heli as Co-axial helis aren't really my idea of fun. This toy was enjoyable for the first couple of flights; however as someone who has flown far more exciting helicopters I quickly became bored with the s107g. This is in no way a bad mark for the product. It does exactly what it advertises and the price is absolutely remarkable. I was overwhelmed with how well it performed and how easy it was to control. Plain and simple its a great product for a great price.Pros: Very stable, Co-axial design helps greatly in this. Gyro makes flying extremely simple and... 4/5 J.
