How does this Eagle Tree Chart Look?

[JohnAu]

Hi i have my Eagle tree logger setup on my Trex 600 E and like to know if this first chart i logged looks ok. I am running a standard Trex600 with 170 gear pinion and 10 teeth gear on motor, i am just hovering with the idle up set to 0-85-85-85-85 and 6s 5200 lipo. Does the head speed read ok for this setup.

Thanks JohnAu.

Just so you know because the pic is abit hard to read , Green is Blade speed, Purple is Motor speed.

You are displaying motor rpm from the brushless sensor, not very useful. In the data recorder PC program you need to perform RPM calibration (from the "Calibration" menu) where you enter motor and gearing data. With this done you can select "Prop RPM/Headspeed" for display on one of the left or right y axis

Hi Lajon, i have calibrated the brushless sensor with gear pinion and motor pinion and number of poles. Its the green line at the bottom of the chart.

Ok, my point then is that you should not display the motor RPM, the scales will then not have to include the +30K values and the headspeed will be easy to read with better resolution.

Also, include pack volts and amps in the chart, this will be always be useful when comparing performance.

Your head speed is about 1940 rpm... which is about right for your setup but it's hard to see because of the graph scale. I just used motor rpm reading and calculated head speed.

33000 / 17 = 1941

Thanks for the tips Lajon, i will exclude the motor RPM.

0636 thanks for letting me know it's running ok at around the right head speed for my setup.
