Details and contents: Fully assembled RTF Co-Co Lama V3 helicopter A great helicopter for both the beginner and experienced pilot. Co-Co Lama V3: You can fly it because it has two 13-1/2” main rotors that are co-axial and contra-rotating on the single shaft. This torque canceling design makes Co-Co Lama stable and flyable on your very first flight. Even a complete newcomer to helicopter flying can fly this at once. The helicopter is 14-1/4” long and weighs 7-3/4 oz. Co-Co Lama is complete and ready to fly and includes a 4 channel 72 mHz FM transmitter, a 4-in-one mixer/controller (electronic gyro, mixer, motor controller, receiver), two motors, two servos, 7.4V, 800 mAh Lithium battery and Lithium battery charger. Charge the flight battery, install 8 AA batteries (not included) in the transmitter and fly it. Even though it rarely breaks in crashes, Co-Co Lama comes with a complete spare set of main blades. In addition, we stock both spare parts and aluminum upgrade parts. Instruction booklet provides some helpful tips about the basics of radio-controlled helicopter flying. Co-Co Lama is not a flimsy toy -- it is an extremely well-built and well-designed radio controlled model helicopter. The 72 mHz radio, the motors and servos are hobby quality products that will provide many hours of service. If you ever wanted to fly an electric helicopter but were put off by the difficulty of flying a helicopter, Co-Co Lama is for you. From RCUniverse.com Product
Review- The instructions also include a nice diagram of the multi-function control system, which controls the receiver, servos, gyro and ESC. The booklet will surely confuse newbies because, in an effort to save on printing costs, the E-Sky folks included detailed instructions on gyro gain controls and swash adjustments for their more complex series of collective pitch helicopters. GETTING STARTED The Co-Co Lama comes with a 72mHz 4-channel transmitter (so pin up if you are flying this at a regulated flying field!). The transmitter has a lighted display which indicates battery consumption. In addition, the transmitter can be converted from Mode 1 flying to Mode 2. Not bad for an inexpensive leisure craft. The battery charger is a dual-use system. You can plug the charge box into your 12 volt gel cell or just plug it into the wall. The 2-cell lithium polymer battery gives the Co-Co Lama plenty of power (we tested at 5,250 feet in Denver) and plenty of duration. Flight times will range from 5-9 minutes. The Co-Co Lama could not be easier in terms of setup
and initial flight. In this respect, the Co-Co Lama performed just
as well as the Megatech House-Fly. In terms of appearance, however,
the Co-Co Lama lacked a bit of the detail and pizzaz of the House-Fly.
The tail is stark white and the canopy sported a rough decal set.
Unlike the House-Fly, the Co-Co Lama's electronics are in full view
through the canopy. The antenna is neatly coiled inside the canopy
and we left it like that. We never experienced any interference
or range issues. One of the features we really liked was the "snap
in" battery tray that provided easy access. The Co-Co Lama has two motors; one to control the top rotor disc and one to control the lower rotor disc. In a hover, the two motors run at equal speed. To yaw the helicopter (rotate left and right about the vertical axis), one of the main rotors either slows down or speeds up to create an imbalance in torque. This results in the Co-Co Lama turning in the direction opposite to the rotation of the faster moving rotor. Since the Co-Co Lama is fixed pitch, collective (altitude) control is governed exclusively by throttle. The lower rotor system provides cyclic control for the ship. Indoors, the cyclic control is plenty responsive. In particular, we were impressed with the servo resolution. In plain English, this means that precise movements of the transmitter sticks are translated into equally precise movements of the servos. This is a key element in a successful model of this type. Indoor Flight Indoors and in large enclosed spaces (e.g. recreation room or garage), the Co-Co Lama is a snap to fly. It performs satisfying figure 8?s and hovers like a tethered helium balloon if you want it to. The Co-Co Lama moves into forward flight, but you really need to keep pressure on the forward cyclic to accomplish sustained forward flight. This is really a boon to novices because letting pressure off the stick will stabilize the craft. Keep in mind that the Co-Co Lama is directed to those who are new to heli flight or to those who simply want an indoor diversion that doesn?t require laser focus. Having said that, you do need to keep your mind on throttle management as you perform moderate yaw maneuvers. As you turn, one of the rotors will slow down in order to unbalance the torque of the main blades. Doing this causes you to lose altitude. Your best bet is to nudge the throttle a bit mid turn. Outdoor Flight The short answer here is to keep the Co-Co Lama inside
unless the winds are virtually dead calm. The little ship is no
match for a breeze and will fly away like a kite if you pop it up
into a wind as little as 3 mph. But this does not diminish our view
of the Co-Co Lama. It was not designed to fly outside in wind. In
our view, the best use of the Co-Co Lama for beginners is to practice
hovering and limited forward flight. For experienced pilots, the
point of the Co-Co Lama is to quench the thirst for heli flight
on dreary days or tune your skills at landing dead center on the
kitchen table. Whether you are a novice or a skilled veteran, the
Co-Co Lama is a fun and easy helicopter to fly. I like the low price of the Co-Co Lama for either
novices or experts, who are looking for indoor R/C entertainment.
Expect from the Co-Co Lama what it was designed to deliver; namely,
a stable platform for learning, but nothing aggressive. If you do,
you will find the Co-Co Lama well worth the investment. |
