Speed Calculator

[RC-Monster Mike]

I doubt you're holding 3.7 volts under load unless its geared pretty conservative - gotta guess on tire ballooning as well(soft tires will grow more). For speed run applications, I set the voltage to whatever the LVC is set to. For day-to-day, I use 3.2 for calculations....I rarely verify the actual speed, though(unless its a speed run, I don't care what the actual number is - more of a feel thing for regular running).
