Walkera Dragonfly 4, Manual

Also, bright spray paint using masking tape makes tracking real nice. Do one only.Eliminates “vibes”
from the head when one of the tapes start lifting. Note there are 2 holes drilled into the bottom of the
DF35 foam blades. When removed and painted, the machine whistles! Intentional, or perhaps to
compensate for pressure/temperature
differences around the world?
Now from here, just work with BOTH blades (equal turns) to get the liftoff at close to half throttle.
Recheck this with a freshly charged pack, as I am not confident a brushed motor and less than a 2k
pack can achieve this. Advantages are that the head spins slower, you burn the battery pack slower
and the whole machine will be more docile.Only issue is the motor may run warmer due to more drag.
This also immediately changes your tail rotor trim settings. The other option is... with a pitch gauge,
find out what they set the pitch at for full throttle, half throttle and idle before turning off switch 8.That
way, it can always be duplicated. Motor disconnected, measure it in “N” and “1”.Lock that Flight Mode
switch again afterwards!
If you feel comfortable with this, try “flying” it with the right stick only. Hand on the tube of course. See
how it tilts left/right and fore/aft. Just little movements, we have not reset the servos yet. That's the
next step. But try this “false flying” without the tail blades for say... 4­5 15 min. flights. Let it get
BORING cause you did it so many times! You are effectively balancing a broom on your right hand,
true hovering is like balancing a broom on each hand. Note the HEAT of the engine every few
“landings” by touching it after the blades stop spinning. This is a really good way to learn the feel of
your
machine! You're also breaking in the motor!
When finished, set throttle to idle. Pull the battery plug... then turn off the Tx in that order. Hey, we
didn't break anything! Don't forget to recharge the battery, they have to be stored charged also!
You probably notice how sensitive that right stick is. The 2 top servos at the front of the machine are of
course the swashplate servos. Without mixing the two of them up...remove the servo arms by
removing the little phillips head screw on each. Using a tiny drill bit or a fine Xacto blade, open up the
NEXT hole toward the center on each. Get the wire Z bend through this new hole and replace with
screw onto the servo. When you put them back on, have everything ON with the motor disconnected
(or 5Amp switch!). Set the stick trimtabs to center. When you put on the Aileron (side to side)servo
arm, make sure it is tilted to the right (looking from the tail) about 3­5
°
