Cobra 3 Channel Mini Helicopter - Elite w/Gyro REVIEW

Review: Cobra 3 Channel Mini Helicopter - Elite w/Gyro

Overview


Control- 8/10 - Easy and precise, although sometimes is harder to control while next to vertical surfaces

Maneuverability- 7/10 - Good but not the easiest to become accustomed to

Stability- 10/10 - Excellent stability throughout all movements

Hover- 9.5/10 - Incredibly easy but it can be hard to maintain exactly equal altitude

Lift Speed- 8.5/10 - Quick lift speed

Forward Speed- 7.5/10 - Good speed but slow acceleration to max speed

Flight Time- 6/10 - Good flight time of about 10-15 minutes but after about 7 minutes there is a noticeable difference in rotor speed

Charge Time- 6/10 - 30-40 minutes

Cost- 8.5/10 - $30-$50

Overall- 8/10


Overall this helicopter is quite excellent, as it flies well and due to its all metal body can SURVIVE ANY CRASH, as long as you're not stupid and you fly indoors.

Unfortunately I have had a bad experience with Cobra and the manufacturing of this helicopter. I flew it a ton the day i got it, and it flew fine. The next day, it couldn't fly, but instead would spin helplessly on the floor, regardless of minor adjustments. It became apparent that it had been poorly constructed, as the top rotor could move separately than its axle.

I really like this helicopter, and hope that mine will be fixed or replaced soon.

UPDATE

Thanks to customer support, a vital screw was located, and i received a free screwdriver to fit it. The screw was located on the upper propeller apparatus, and clamped the apparatus to the drive shaft. After it was tightened, the helicopter flew as well as it had out of the box.


Videos


Neither video features this helicopter, although a previous model and a similar one.

Prometheus

In Greek Mythology, Prometheus is a Titan and the brother of Atlas and Epimetheus. Prometheus and Epimetheus were entrusted with the job of "designing" all of the animals. Epimetheus made animals with claws and armor, and countless other tools for survival. Prometheus decided to create one perfect being, and thus he created mankind. Prometheus realized that humans, with soft skin and no apparatus for battle like Epimetheus' creations, needed a tool that would place them above the rest of the animals, and closer to the divine. He stole fire from Zeus and gave it to the humans. As a punishment, Prometheus was bound to a rock in the Caucasus where every day an eagle would eat his liver, which would regrow by night.

Polyscheme

"Polyscheme is a cognitive architecture designed to achieve human-level artificial intelligence and to explain the power of human intelligence. We choose and evaluate research efforts primarily on how they help advance the ability of systems to do what people can and computers can't yet. Polyscheme has enabled computer models that explain how background knowledge and context can be used to understand language that is ungrammatical, nonliteral and ambiguous; robotic systems that can reason and plan while incorporating incomplete and noisy information from a dynamic environment; and computational models of children's physical, social and linguistic reasoning."

To me Polyscheme looks like part of the development of true Reason in computers and computational sciences. This topic is very important and full of potential. Nobody wants a doctor who can only read from a book, and everybody wants a doctor who can tell them if it is safe for them to run with their unique injury.

This also is a progression of our understanding of the human brain. We know some, but not much, about how the human brain reacts to stimuli, but we know even less about what actually gives us humans strong emotions, reason, and educated decisions; or individuality, humor, and opinion.

Polyscheme and Prometheus- An Quick Introduction

Polyscheme and Prometheus will discuss or concern various topics across many fields of knowledge and interests. The focus of this blog will be on a wide variety of sciences as well as various hobby-like activities.
