Random Parameter Solver

This calculator lets you pick what parameter you want to solve for. Be aware that this calculator does NOT take several parameters into account (such as tire ballooning, drag, kv drop vs current/motor resistance, etc). This is used to get a rough approximation.

Simply fill in what you know, but leave the one field blank which you would like to find the answer. Remember, you must leave one and only one field blank. Press the "Calculate Unknown" button to display the result. Some fields can be automatically filled with pre-determined values by selecting from the associated drop-down list.
