CSM360 Simple Setup

This isn't meant to replace the instructions.
Once you are familiar with the gyro, reread the instructions
and check here.

First plug the rudder servo directly into the rudder
channel in the receiver. Check the direction. Right rudder
should pull the control rod to the front of the machine on
most brands. Verify this by standing behind the model and
watch the tail blades as you give it right rudder. The
leading edge of the tail blades should move left
 
Remove all subtrim, stunt trim , revolution mix and any other
mix that involves the rudder channel.
Center the trim tab on the rudder. For the CSM gyros a fairly long
arm seems to work better. You can start at 15mm. Fit it so
the arm is about 90 degrees to the rudder control rod.
Adjust the length of the rod so the t/r bellcrank is 90
degrees to the rod. This might not be perfect, but it'll
get you going.
 
Turn off the power to the model. Now go ahead and plug the
aux-in into channel 5. Channel 7 has some issues that
complicate things and we're trying to keep this simple.
Futaba guys need to inhibit the gyro function
 
Set the ATV on channel 5 to 60% on both sides. Set the ATV
on channel 4 to 90% on both sides.
 
Adjust the gain pot to about 50% just for grins. Turn the
model back on.
 
Check the direction of the gyro. You know that right rudder
pulls the rod forward. Yaw the machine to the left and
watch the rod. If it moves forward you're in good shape. If
not, either remove or replace the reversing jumper.
 
Move the rudder to one side and let go. In heading hold,
the slider should stay in place or drift slowly back to
center. In normal mode it will return to center
immediately. Put it in heading hold. Now adjust the subtrim
on the rudder until the rudder stays put and doesn't drift.
If your transmitter allows it, cut the trim rates to 50% to
allow for finer adjustments.
 
Now go hover the model. It will want to swing rather
violently as it get light on the skids and before the tail
blades gain the authority to control yaw. You'll anticipate
this after a few times and it won't be a problem.
 
If the tail wags in a hover, lower the gain a couple points
and try again. If it doesn't wag, raise the gain a couple
points until it does, then back off a couple points.
 
Go ahead and use the trim on the rudder, but when you get
it trimmed, you'll want to transfer that to subtrim so it
will be right in all modes.
 
If the gyro doesn't work at this point, it's broke and
needs to be serviced.
