Run time on new motor

[daddycool 8]

Is it possible to work out run time of a new motor? I have a stock Dark Impact with rv20 esc and 3300 battery, and interested in the super stock tz, but not if I’ll only get 5 mins play out of it. Currently get 10-15 on current setup 

Thanks

Technically yes, if you know how many Amps the motor draws ,the gearing, surface, weight etc.

If its a faster motor, it draws more amps, so it'll be faster,  but not last as long. A brushless motor is more efficient, so you can go slightly quicker and last the same time.

Hammering a 6.5t brushless, I get 6 mins out of a 3800mah, I think the super stock are 23t, a silver can are 27t (lower the turns the faster the motor), so it'll not last as long, but not that much tbh.
