Draganfly DRAGANFLYER X8, Руководство пользователя

Страница: 76 / 86

Repeat this with the pitch (right stick, forward back motion), and yaw (left stick, left/right
motion) controls one at a time. By using these controls try your best to keep the
Draganflyer X8 stationary. The Draganflyer X8 may drift in one or more directions. This
is what the trim tabs on the handheld controller are for. These trim tabs
should be moved in the opposite direction that your helicopter is drifting.
For example, if the Draganflyer X8 wants to drift to the right you would
need to apply left roll trim. When inputting trim corrections only use very
small amounts and observe the effect. In some cases the Draganflyer X8
may drift in more than one direction. Start by correcting for the largest noticeable
movement, then move on to the next one. You should become comfortable with trimming
the helicopter, as it may need to be done after a crash or rough landing. Once all of the
trims are adjusted correctly you can move on to the next lesson
NOTE: When landing there should be no forward speed, the
Draganflyer X8 is designed for vertical takeoff and landing. Allowing
forward speed on landing may result in the helicopter tipping forward
and damage to the rotors may result if they come into contact with the
landing surface.
Do not under any circumstances fully reduce the throttle during flight,
this will cause a drastic decrease in altitude and may result in an
unrecoverable attitude and crash.
Lesson 2: Basic Hovering
In this lesson, we will lift the Draganflyer X8 off of the ground a small distance and
practice hovering in one spot. For this lesson it is best to fly over a flat, smooth surface
again. Stay less than one foot above the ground, this will greatly lessen the chances of a
crash. Remember that if you get disoriented or lose control simply reduce the throttle to
minimum immediately. Trimming the Draganflyer X8 is important and should be checked
each flight so that it does not wander off on it’s own. For safety, stand about 15-20 feet
away from the Draganflyer X8, slowly increase the throttle until it begins to lift off from
the ground.
Use gentle, smooth movements of the pitch, roll, and yaw controls to keep the helicopter
on a stable, level position. It is important that you use the yaw control (left stick: left and
right) to keep the front of the Draganflyer X8 pointed away from yourself. At this point
do not worry about maintaining a perfect hover, just concentrate on keeping the
Draganflyer X8 level and within an imaginary 10 foot by 10 foot square. If the helicopter
starts to oscillate back and forth simply reduce the power to land and start again.
Learning to hover is the most difficult part of flying a radio control helicopter so it is ok
if it takes a while.
