Added a system wiring diagram for using the Traxxas EVX2 ESC. 08-04-2009: Fixed differential manufacturer typo. In the Top Speed Estimator, removed the suggested "1:1 rollout" pinion in the results section. This was changed to show the current rollout ratio. The pinion tooth count to achieve a 1:1 rollout is still listed in the pinion table (click the gears icon in the results section). Added more verbiage to explain rollout and the "1:1 Rollout" rule (in the help function). Also changed the error message to be more appealing.

Fixed LST/LST2 transmission ratios. Added LST/LST2 FOC transmission ratio. Added Hot Bodies D8 differential ratio. Added a note for the old RCM slipperential stating V1 is discontinued. Added Mod 1.5 gear pitch. Added Losi MRC transmission ratio. Removed battery charger data table, selection box, and all code relating to pre-set battery charger information. Mew chargers are released far too often to make this useful. Added new feature to the Power Calculator page. Once the user enters the data into the form and calculates the power figures, it will also provide a table listing estimated pack capacities to get the same runtime at different voltages. Removed the Sky & Technologies link (Quark) since the address is no longer active. Removed the Beta alert on the BL Parameter Comparison page. 03-04-2009: Fixed "form export" issue in Opera browser. Was using the DOM element.getAttribute() method but the attribute I chose to use ("text") was apparently a reserved word and simply returned a hex code instead of the display text. Changed the custom attribute "text" to "expText" on several pages. Also fixed the export form feature so that it displays empty fields properly (use   instead of empty string). Re-added Savage transmission gears since I believe the values are now correct. Fixed dead help window links in a few pages. 03-01-2009: Added Proline Switch (Slash) tires to the Proline 2.2" rim section for the tires. Changed Baja spur gear pitch is Mod 1.5. Thanks to RCM forum member doo540 for this info. Alphabeticalized tire list.

Removed Savage transmission ratios until I get the proper gear tooth counts. 02/21/2009: Re-ordered Medusa motors so they appear in the drop-down list in the same order as the rest of the motors (largest to smallest). Added diff ratio for "typical" truggy since there was a generic buggy ratio already. Added HPI Flux diff ratio. 02/19/2009: Changed the "pinion vs speed" table to be in different order. 02/17/2009: Added shock information for Jammin X2 Truggy. 02/09/2009: Added shock information for Losi Muggy and MGT MMT vehicles.

Patrick del Castillo of Castle confirmed that the use of the resistor may cause an inoperative unit. Fixed the power rating of the resistor on the "no spark" page. I forgot to figure in that the dissipated power is not constant over the charge cycle. Changed the list of selectable charge time values to more common settings. Updated the power ratings of the Neu motors. 07/28/2008: Added differential and transmission ratios for Traxxas E-Revo. 07/23/2008: Added Traxxas Slayer differential and transmission gear ratios.

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.

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 speed limits in the motor selector page. Fixed a bug in the "something else" entry below... 04/20/2008: Added something else that has nothing to do with R/C. Pretty pointless, eh? 04/02/2008: Added power calculator. 03/30/2008: Minor fix to the CSS style sheet for the menu. 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.
