WowWee Bladestar Flame Indoor Flyer Review

Average Reviews:

This is a flying machine unlike anything you've ever seen before. It's not an airplane, it's not a helicopter, it's not an autogyro, it's not an ornithopter with flapping wings. It's a powered maple seed. I'd have never thought of it, and you probably wouldn't have either, but the Wowwee designers did, and they deserve lots of credit for this masterpiece of out-of-the-box thinking.
I read about it in the magazine of an engineering society that I belong to, and the reviewer couldn't figure out what kind of "control equation" allowed an object with no non-rotating reference elements -- everything on the Bladestar spins -- to operate under directed flight. He must have come from the same aeronautical tradition as the ones that proved that a bumblebee can't fly. (We now know that insects use nonlinear "unsteady flows" to gain more lift than traditional aerodynamic equations provide for.)
While the Bladestar employs "AI" according to its advertising, it's not as smart as a bumblebee. But it can successfully avoid light-colored objects under good conditions. In the jargon of AI research this is called situationist autonomous control. If the room you're flying it in has dark walls like my living room, you'll have to guide it away from them yourself. The blades do collect dings if you fly it into hard objects, but the wingtips are covered with heavy foil that you can smooth out and it's nearly as good as new.
It naturally hovers very stably, so you might expect it to respond to the controls like a UFO in a video game, but no, this is a real flying object with gyroscopic effects when it tilts to move sideways. It takes a little bit of practice to learn to anticipate these movements and coordinate the controls appropriately. I was practicing landing on target after about 5 flights.

Bladestar is a revolutionary indoor flying machine that changes helicopter flight as we know it. This is the first flying toy with a sensor-based navigation that enables it to glide itself through the air as it avoids ceilings and other obstacles. Alternatively you can control it with the three-channel digital IR controller, and with the dogfight accessory attached you can face-off two bladestars to see who will win. When you notice power loss, simply recharge right from the controller. Made from light "high-flex" materials and designed to be crash-resistant, Bladestar is built for indoor flight. Requires 6 "AA" batteries, not included.

WowWee Robotic DragonFly - Green (49 MHz) Review

The 15 year old I bought this for wouldn't take it outside to play with it, wouldn't read the instructions and generally annoyed his father with it. But that's fifteen for you.
When I got a chance at it I found it easy to fly and maneuver, even in the house. The charge lasts about 7 minutes which doesn't seem like a lot but prevents the toy from becoming boring. I would recommend this for any age except 15.

REMOTE CONTROL DRAGON FLY HELICOPTER - item #66831 Review

REMOTE CONTROL DRAGON FLY HELICOPTER - item #66831

DO NOT BUY THIS PRODUCT. there is to controll to go forwards or backwards so all you can do is hover. also i tried to fly in 1mph winds and I couldn't stop it from drifting off after every take off. there is no steering so the only thing it does is hover while you controll the way it faces before it crashes. mine broke after a fall i was forced to do otherwise it would have drifted over a fence. the fall was only about 2 or 3 feet but it broke the back end off entirely. worse you cant get your money back. i am very disapointed with it. DO NOT BUY THIS PRODUCT.

Dragonfly Radio Control RC Helicopter Hughes 300 9093 Review

Dragonfly Radio Control RC Helicopter Hughes 300 9093

My first experience was in reading the operator's manual. The English translation of the instructions from their original language was at times humorous and quirky, but also confusing and difficult to follow. The quality control around the manual was the first of many quality issues.
After preparing the craft and charging the batteries (for 3 hours), I took an initial test flight to determine if the counter rotation needed adjustment. It did, but upon touching a screwdriver to the potentiometer, the plastic head fell off and to the floor. I was able to make the necessary adjustments by manipulating the potentiometer directly with a small tipped tool.
I performed several test hops between 1 and 3 feet high, to familiarize myself with the controls. During the second hop a minor crash on the floor caused one of the posts that hold the cowling to snap off. I glued the post back in place and tried again the following day, but the glue never held securely. I may have to use heat to "weld" it back on.
Next to go was one of the two tail fins. The fin was very loosely attached and was lost during a low level encounter with a bush. I am not sure why one fin is well attached and the other is so loose. Controlled Flight seemed to be possible with just one fin
Next, after a "tip over" in the lawn, the main rotor stripped free from its drive post. It would not reseat, requiring me to use more glue (and making future rotor blade changes challenging).
The quality of instructions also left a lot to be desired. First, there were no flight instructions for beginner rotor-craft flying - for a product aimed at age 14+, this would seem important. The instructions warned of flight in high winds. Although "high" was not specified, I discovered that attempting flight even with a 1-5 MPH breeze made control nearly impossible. There may be ways to control the craft in this situation, but the instructions provide no guidance to the novice flyer, even for calm and indoor flying. Without roll controls, the craft moves in unpredictable directions that depend, in part, on rotor speed, requiring constant correction from the tail rotor. The tail rotor seems to run either too fast or too slow when attempting to hover. The angle of the tail is adjustable, as is the angle of the tail rotor. Both adjustments came loose during the first 5 minutes of test flight and without guidance on optimal positions; I had to experiment with their positions.
I am slowly getting a handle on how to fly the "FLY", and I hope that I have experienced the worst of the quality issues. I do not recommend it to anyone.

Discovery Exclusive Radio Control Flytech ? Dragonfly Review

I am deployed to Iraq right now and I was looking for something to mess around with in our hanger. I atomatically ordered two knowing I would break one and I could salvage parts without waiting forever. The first one's tail prop would ot trim out and just spun out of control and crashed. The second one charged up and flew great right outta the box. After messing with the trim a bit and mastering the controls It is surprisingly controlable. I've crashed the thing into the concrete and the metal hanger walls about 100 times and haven'tbroke anything yet. Make sure you have plenty of room to practice so yours stays as durable as mine has.
