Swashplate Eccpm Set Up - miniature aircraft Fury 55 X-CELL Assembly Instructions Manual

swashplate eccPm set up:

Now that you've built your new Fury 55 helicopter, you have to make the servos work together. The Fury 55 is an eCCPM model,
and requires a specific radio program for the servos that control the swashplate. eCCPM is a mix that is already programmed in your
transmitter, you just have to fine tune it to your Fury 55 and here's how:
The very first thing you need to do is tell your radio that a 120 degree eCCPM mix must be used. All modern transmitters should
have 120 degree eCCPM built programmed from the factory. Consult the manual that came with your radio! Before you turn on your
Transmitter and power up your servos, you need to make sure they are centered. Make sure you use the MA128-36 C/F servo alignment
tool! With your transmitter and receiver powered on, put collective stick in the exact center with all three swashplate servo horns
removed. Then put the horns on so they are 90 degrees to the linkage. This centers the servo horn on the servo and assures that there will
be equal travel on either side of the servo's center point. If you find that you cannot get the servo horn exactly at center, you have two
choices. You can flip the horn 180 degrees, sometimes the splines will line up perfect, this is the preferred method. You can also use a bit
of "sub-trim" to center the servo. You really want to avoid using subtrim because it makes leveling the swashplate a little more involved.
Now you need to make sure that your servos are all working together. What we mean is the three collective servos need to be plugged
into the appropriate channels, i.e. the elevator (which is the servo that controls the center ball on the swash) needs to be plugged in to
channel 3, the aileron and pitch servo (the ones that control the sides of the swashplate) need to be plugged into channels 2 and 6 (it
doesn't matter which channel just either servo, into either 2 or 6 on the RX).
IF you use a Futaba or Hitec transmitter, the channel assignments are a little different. For Futaba, Elevator is channel 2, Aileron is
Channel 1, and Pitch is Channel is 6.
Then, using the servo reverse screen, you need to make sure that the servos are doing the proper function. All the servos need to move up
(or down) when the collective stick is moved up or down (it doesn't matter if the collective is reversed, we'll fix that later). If it doesn't,
you need to (one at a time) reverse the channels on the servo reverse screen until all the servos move in the same direction when the
collective stick is moved.
Now the aileron and elevator functions need to be sorted out. When you move the right stick right and left, the swashplate should tilt to
the right and left (it doesn't matter if it moves right when you push the stick left, we'll fix that later). Also, when you move the right stick
forwards and aft, the elevator should tilt forward or back. (again, it doesn't matter if the FUNCTION is reversed)
Now that the SERVOS are all moving in together, we need to be sure that the SWASHPLATE is moving correctly for a given command.
Pull up the Swash Mix screen. Futaba calls it "Swash AFR" There should be 3 functions and they'll look like this:
Aileron: 60%
elevator: 60%
Pitch: 60%
So, if the the swashplate tilts left when you move the cyclic (right) stick TO the right, make the value of 60% for Aileron NEGATIVE
or -60%, and likewise for the elevator, so if the swash tilts forward when you pull the cyclic stick BACK, make the value of 60%
NEGATIVE or -60% to correct it.
The swashplate should move up and down with the collective stick, and if you RAISE the collective stick, the blades should show
POSITIVE PITCH. And if you LOWER the collective stick, the blades should show NEGATIVE pitch. IF that function is reversed,
again, make the value of 60%, NEGATIVE 60% or -60%.
To ensure that your Fury 55 is set up as precise as possible it is very important that you follow the pitch curve set up guide, and you
properly level the swashplate. There are several different tools for determining if your swashplate is level. We recommend the MA3000-
10 Swashplate Leveling Tool.
Place the swashplate leveler on the swashplate and ensure that it is level. The collective stick should be at the center with zero degrees
pitch on the blades. At this same time as described in the pitch curve set up guide, the swashplate should then be in the center of its
travel, and the midpoint of the pitch curve should read 50%. If the swashplate is not level, you can use subtrim to level it, but the
preferred method would be adjusting the linkages that connect the swashplate to the servos! If you find that you have to use more than
a couple of clicks of subtrim on any channel, you should put it back to zero, and adjust mechanically by adjusting the linkages to the
swashplate. After the swashplate is perfectly level at center stick, you need to level it at the extreme pitch range, i.e. full positive pitch
and full negative pitch.
Place the Collective stick at full positive stick with the swash leveling tool attached. If the swashplate is not level, you will use the
End Point screen or Travel Adjust screen. For instance, if the swashplate tilts slightly to the right at full positive pitch, then you will
need to increase the travel for the servo that controls that swashplate ball. Now put the collective stick at full negative, repeat the same
procedure with the end points. You do have to be careful that you don't create any binding at the extremes of the swashplate's travel.
