Prop Constants for Efficiency Determination

DataSheets:
See Hyperion Emeter here
See Titan Brushless ESC here

See "PropTalk": An introduction to props, power constants, and power factors - and how they allow us to easily determine the efficiency of a power system using the Hyperion Emeter.
Hyperion continues to test propellers for prop constants and power factor.  There are many propellers to do, and all tests must be repeated several times to insure accurate data.  Next on the list are the APC SF series, then GWS SF and HD types. We welcome your suggestions for propellers to test, but please note that we will not be able to supply data on demand, nor tell you when a particular prop or series will be listed.  When we have more constants to publish, you will see them here.  We especially welcome modelers from all over the world to send in test data of your own which we may publish, with your permission.
