Basic Model/Radio set up
The X-Cell Whiplash is an eCCPM model. This means that the servos that are connected to the swashplate move
together to achieve the function requested from the transmitter input. The transmitter mixes the channels required to
achieve the correct movement of the swashplate. The X-Cell Whiplash uses a very simple “direct” servo to swashplate
system that decreases the overall parts count and complexity of the model.
The very first thing to do, is center the swashplate servos. Simply align the servo horns so they are 90 degrees to the
servo, and the linkage is 90 degrees to the servo horn. Ideally, you rotate the servo horn until the servo is centered,
eliminating the the need for using sub-trim.
For the pitch, aileron, and elevator servos:
In your radio
• ATV (servo endpoints) should be at 100%.
• Set all trims and sub-trims to center or zero.
• Set an initial linear pitch curve as a straight line (sample points: 0%, 25%, 50%, 75%, and 100%).
• Make sure there is no mixing enabled for cyclic channels at this point.
• Center the collective stick and make sure all the cyclic channels are centered.
On your model
• Mount each ball into a cyclic servo arm hole approximately 19-20mm from the center of each arm.
• Slide the servo horns for each channel onto each servo exactly in the middle of its travel.
• Failing to get them set at center will create interaction in your swash plate travel.
• If possible, center the horns on the servos without using any sub trim. As a last resort, use the sub trim function to pre
-
cisely center each servo.
• Make sure you install hex nuts on the ball retainer bolts using thread locking compound.
• Make sure you install servo arm retainer screws.
For the rudder servo:
In your radio
• Make sure the gyro is in non-heading hold mode. Refer to your gyro manufacturer as to how to enable this.
• Rudder servo endpoints (ATV) should be at 100%.
• Make sure there is no mixing enabled for rudder channel at this point (some radios mix throttle to rudder by default).
On your model
• The ball should go into a hole approx 13-15mm from the center of the servo wheel.
• With your rudder stick centered, rotate the servo wheel until you find a spot that aligns properly and then slide the
servo wheel onto the servo exactly in the middle of its travel. Do not use any sub-trim.
• Now make sure that the T/R bell crank is aligned. The 90 degree pitch slider on the tail case should be in the center
of its travel. Adjust the links as necessary to ensure this is correct.
• Make sure you install hex nuts on the ball retainer bolts using thread lock.
• Make sure you install servo arm retainer screws.
• Set up the gyro according to the manufacturers specification in the manual included with the gyro.
