   * We moved IP position to find where it does not touch anywhere, but TF showed resonant frequency was higher. We think heat link make some torque.    * IP was moved to find where it does not touch anywhere, but TF showed resonant frequency was higher than before. We think heat link make some non ignorable torque.
