R/C CALCULATIONS RELEASE NOTES Format (in reverse chronological order): MM/DD/YYYY: CHANGES 07/23/2008: Added Traxxas Slayer differential and transmission gear ratios. Clarified the information and re-arranged the "Lithium Battery Charger Data" page. 07/21/2008: Changed the gear calculator to calculate both diameter or tooth count. Removed redundancy Receiver Power Wiring options in the wiring page. 07/17/2008: Added Paypal donation link to the bottom of all pages. Changed some images and back-end code. Should be transparent to the user, but facilitates some future changes I have in mind. Fixed the Crimefighter LPR tire size from 5.25" to 5.8". 07/11/2008: Added ratios for HPI E-Savage. 07/06/2008: Added ratio calculation to the two-speed mesh page. 07/02/2008: Changed the two-speed mech calculator to be more user-friendly.

Added a check to the oil mixture calculator to make sure that the target mixture viscosity is between the two source fluid viscosities. Added Kelvin to the temperature unit conversion. 06/25/2008: Fixed a bug in the "System Wiring" page causing image display error when using FireFox web browser. Thanks kirbysdl. Changed some of the underlying radio button selection code in the "System Wiring" page, which is totally transparent to the user, but easier for me. :) Changed differential "HP Pro" to "Lightning Stadium Pro" and placed under "Hot Bodies" heading. Thanks again Arct1k! 06/23/2008: Re-added LMT motors but put them at the bottom of the motor list. Added E-Revo/3905 E-Maxx spur gears Changed "32p" to "mod 0.8" for Traxxas vehicles. Mod 0.8=31.75p, so it works fine with 32p. Added Castle Creations 6800 motor. 06/21/2008: Changed the gear pitch description for the Slash from 32p to 48p. Moved all the BEC information to the FAQ page. Changed the FAQ page to have collapseable sections.

Added power ratings for Neu motors. Info provided from RCM member rabosi via http://www.nesail.com/detail.php?productID=3859 Added power ratings for Feigao motors.

This estimate is quite rough, but good enough until actual numbers are provided. 06/09/2008: Added ratios for Traxxas Slash. Some may be combined with the Rustler/Stampede. Removed "Effective Speed Rate" from top speed estimator. Wasn't providing any real value. Moved applicable help sytem messages to the respective pages.

It appears IE6 does not like the value "transparent" for the border color... 03/26/2008: Added transmission ratios for the new Emax (3905) Changed the code for transmission ratios to show and calculate multiple ratios. Before, any additional transmission ratios had to be entered somewhere else. Updated Neu motor data for 1527, 1521, 1515, 1512, and 1509 series. Also added any newly listed motors in these series.
