Hello All, Yesterday, I visited BJ and he performed a demo fight in the "newly rebuilt" ship. A couple of observations: The ship is both very smooth and quite, smoother than my Exec from years ago. I must say he has done quite a remarkable job with the tuned exhaust/muffler.

Run up Report:

I sat in the ship after BJ's flight with him kneeling right beside--I think he was praying that I didn't screw this up. I brought the throttle up to take off RPM of 6000. Between idle RPM--2000 and take off RPM--6000, you rotate the throttle grip only about 1/4". In other words, it takes very little turn of the throttle and you're at take off RPM. Based on this, it appears that "digital read out tachs" and single gauge engine/rotor RPM tachs, where you have split needles, would not give us the details of RPM adjustments. BJ recommends that an individual Rotor RPM tach and an individual engine tach be used because the combination gauge has only about half as much arc as the dedicated gauge. The larger arc gauges are more sensitive, have more detail, and show better whether the RPM's are increasing or decreasing and at what rate; i.e. better feedback as to what is really going on.

In a few weeks many of you will have an opportunity to experience the same thing at Arlington. I look forward to hearing your observations,
