Change Log





10/1/2006
Continued to evolve Pick Motor.

9/18/2006
Added color highlight on graph to indicate prop RPMs that may exceed manufacturers safety specs. If the prop label is in black, then the prop RPM is estimated safe. If the prop label is gold/yellow, then the prop might be operating at an unsafe RPM and you should consult the manufacturer's specifications on that prop. If if the prop label is red, then the prop RPM is exceeding the manufacturer's RPM recommendation.

Also fixed an issue in regex than prevented Model Motors URL from being accepted.

Added test code for "pickmotor"

8/15/2006
Changed DB schema, which should be mostly transparent. This change adds the notion of a "best trial" associated with each motor. Down the road this will make it easy for folks to vote on the trial data they like the most and that trial data will be used for searches.

Increased thermal power to 0.9 * motor weight. Thermal time constant remains 0.6 * motor weight.

Lots of cleanup on the search page, hopefully making it easier to use. This is the most used page on the website so hopefully this helps. Fixed a bug in specifying the search strings so that they are properly URL encoded.

Lots of clean up on the Motor Details page. Users can now edit their data, as well as delete their data. Comments can now be entered and viewed. An extra table was added to show how efficiency increases with voltage and also as a launching point for graphing other voltages.

Added a range of thrust and power calculators.
