The Lama V4 can be controlled super accurate, but it is the manufacturer Esky very poorly adjusted.
Mine has at the beginning of the increase of speed or when starting up so much vibrates that I just so emergency landing was him because the blade holder to adjust after the first flight, the rotor blades, it is necessary to adjust the clamping of the rotor blades and the adjustment of Fernbedienungstrimmung for Nick was not enough, so I had to adjust the Anlenkungsstange the servo, this is usually sufficient already half a turn from, the rest can be done with the remote control, with a perfectly trimmed Helicopter all trimmers are in the middle position. (Except for the pitch, which should be at the bottom.) All this is correctly described in any manual, so you should have a little idea and bring technical understanding, otherwise it is namely after the first crash just in the corner.
It is worthwhile in any case for a beginner Trainingsgestell equal to order with, so you may save at the beginning of many parts, such as rotor blades, inner and outer rotor shaft, landing skids and gears.
The supplied software does nothing, because it is totally unrealistic, because there already crashes the helicopter from the smallest faulty operation, where you have him in the real world can capture again loosely.
All in all, the really a horny basement, to which I have my still converted to Xtreme Look and converted all plastic parts on Alumimium, now he is to be controlled even more toxic and more precise, since the aluminum parts are made much more precise than the plastic parts and they also have no wear.
This helicopter is designed for beginners who are looking for something else as for professionals for winter equally well suited and with always new tuning remains the thing interesting.
