The Walkera HM helicopter is a great middle of the road device for those who want to get used to the more advanced remote controlled helis. It is a step up from the Syma S107 helicopter, but still great for beginners.
Walkera HM Helicopter Flybarless Series
Whether it’s a 4 channel (the V200) or 6 channel (the V400), it allows the flyer to get used to all the maneuvering controls before moving on to more advanced RC helis.
The purpose of the flybar is to help stabilize the helicopter, but in some ways it might feel like it is dragging. The flybar is trying to level it out or stabilize the flight, while you are trying to maneuver it to fly at the angled speed you want it to go. This puts a little more resistance in the flight and can eat up power and as such, flying time.
With a flybarless system the reduced resistance along with low power loss allow for easier control, longer flying times and improved efficiency.
The flying time for a Walkera HM helicopter in this flybarless series ranges from 8 to 11 minutes per full battery charge. You may think that since the flybar was used for maneuvering control, that having the flybarless system means you’ve lost this control. Not true. Instead, these flybarless systems use gyros and software to auto adjust the flight for easier control and safety for beginners.
The Walkera HM helicopter models V200 and V400 bear some similarities, but there are some differences as well. Both need main and tail rotors to balance out their flight and both have three-axis gyros aiding their flight control. However, their main difference can be visibly noted in their sizes.
The V200 has diameters of 440mm for the main rotor and 94mm for the tail. On the V400 these numbers are 635mm for the main rotor and 136mm for the tail. The overall size and weight of each version are directly proportional to these measurements: the length of V200 is 432mm and it weighs 268g, while comparatively the V400 is 650mm long with a weight of 510g.
These differences affect the necessary power from the battery to give the needed strength for lift off. The V200’s battery is a 7.4V that has a 1000 mAh lift power while the V400’s battery is 11.1V with a 1200 mAh lift power. Again this is necessary to allow for lift off of the extra mass.
The V200 and V400 are excellent flight worthy models that have proven to be a positive step toward advancing one's skills at flying RC helis. They have proven to be very stable right from the box, with minimal construction needed.
In a very short time the enthusiastic remote control pilot will experience the thrill of flying and maneuvering their new Walkera HM helicopter, be it the V200 or the V400. Click on images to buy from XHeli.
