For beginners who are considering which radio controlled helicopter to start their hobby with, the Walkera Dragonfly 4 would be an ideal choice. Many experienced hobbyist have discovered this is also a great way to move out of a micro helicopter onto a larger one. The last time the model 4 was updated was in 2006, without any reason to change since then, you can know you're getting a reliable RC helicopter.
Abilities and Durability
It has flying operations that are comparable to most modern-day helicopters. Able to roll, yawn, hang, and move forward and back, it has an excellent performance and flying time that you will appreciate more upon seeing it for yourself.
Performance, maneuverability, stability would be enough for many hobbyist, but along with all that it is made with ultra tough carbon fiber material that has superior strength and can endure high impact events similar to a crash.
Versatile and Usable
Once you have it out its box there is not much to do to get ready to fly, all you have to do is screw the blades on, charge the battery and install it, and you're ready to go!
Designed for indoor use as well as outdoor flights in calm winds, the dragonfly 4 has lots of versatility. The usability is taken to another level with the computer simulation serial interface cable which allows simulation software to be downloaded so you can fine tune your skills without the risk of crashing!
Stability in the flight is what you can expect even if you're a first time flyer you'll see that you can control it with little trouble.
High Tech Control
The controller has outstanding response and the performance of the 4 channel controller is tough to beat. Employing anti-interference technology makes this controller more reliable and less likely to have any malfunctions caused by man-made or natural interference.
What I really like is what I call the "smart" feature because if you ever did lose control of your helicopter because the transmitter shut down, it has an auto-pilot feature which allows the receiver to continue to operate stably with no malfunction. Is that smart or what?!?
The Dragonfly 4 is Good and Here's Why
It quickly follows inputs from the pilot with outstanding response because it has been optimized for performance. You can fly 10 to 15 minutes off of a single charge allowing you to really put it through its course. And believe me you will be able to!
It has an excellent design that performs well and is very enjoyable to pilot, here are some of the features and reasons it's a great buy:
- The blades provide superior lift. If you crash or have a heavy landing the blades have a pop-off design that provides extra protection.
- Secures battery support that is adjustable to meet your preferred balance for flying.
- Precise hovering because of the 3-point ball bearing swash plate that comes standard.
- Set up is simple because of the pre-positioned servo mounts.
- Fight times are extended as a result of the efficient yet powerful main and tail motors
- Three-in-One Mixer/Gyro/Receiver Board.
- Four Channel RC set that has left, right, up, down movement (Rudder, Aileron, Elevator and Throttle).
- Either a Left hand throttle - Mode 2 transmitter or Right hand throttle - Mode 1 transmitter is available.
- Designed for indoor flying or outdoors within a 500 square foot area.
- Easy to find spare parts and accessories.
It has good size at 24 inches long, 6 1/2 inches wide and weighs a surprisingly light 10 ounces without its battery. The main rotor is 20 inches and the tail rotor is 6 inches. It has a power supply of 8.4V provided by the NI-MH battery which accounts for the longer flying times. Standard is the 120 volt charger.
Conclusion
I think it is a really good investment for anyone looking upgrade into a larger scale helicopter, and give you an excellent training and preparation if you are hoping to fly the big birds eventually.
