Hi guys,

Did some more runs today and added more numbers.
A pattern is emerging

The DA60 is definately a torque motor and likes bigger props.

Andy also passed along an older link on another site. Another fellow did similar testing with the same 3 pipes I am using. He has a little more math and science in his information. But reaffirms the results I am getting

Here is the link

Here are todays results

No, thats the way it comes. Curved down like that, or straight out the back.
Weird......

No, the black sensor in the bracket is a regular rcexel hall sensor.
The only thing specific to DA is the white bracket to get the sensor in the correct position.

I checked my DA 100 and my zdz engines and they are reversed polarity from my DLE111 and my eme engines. the DA 60 may be different from the DA 100 but I doubt it ,I would check to make sure . just a thought there may be a few more ponies in there yet LOL.
I completely forgot about that.
Yes, i had flipped the sensor over inside its shroud.
