Known Issues
------------

 1. This software now works with PCM systems. As before, CH6 must be the final (latest) signal
    that the TH-2 receives and MUST NOT HAVE A GYRO ON IT.

 2. A digital filter was added to the rudder function.  It is used to reduce noise that can be picked
    up by the yaw gyro due to vibration.  It has four settings (off, low, medium, high).

 3. A constant was added (21) to control the rudder filter.  Be sure to initialize it to the desired
    value.

This release contains the following components:

TH-2B004.HEX        ;TH-2 application software
TH-2B004.def        ;TH-2 constant definition file
TH-2B004.cst        ;TH-2 default constant file

CCPM4.WMF           ;Tech Link support file
th2_inst.bat        ;Installation batch file


Known Issues
------------

  A bug was fixed in this version that caused a single frame (TX) glitch event to occur on an
input channel that used an asynchronous gyro.  This glitch event only occurred once every few
minutes and lasted only one TX frame.  Due to mixing more than one servo was affected.  The
actual pulse width of the glitched channel was clamped to 800 microseconds.
