E-revo Motor "ARG CONFUSED"

[BrianG]

From the many setups I've seen here, it seems to be:

- For a light vehicle (3-5lbs), an S size motor is used
- For a medium weight vehicle (5-8lbs), an L motor is used
- For a heavy vehicle (9lbs+), an XL motor (or larger) is used

Of course, there can be some overlap, but the motor and vehicle weights tend to fall this way.

Then, you figure out the voltage you want to use.

Then, figure out the working rpm based on ~80-85% of the max recommended rpm for whatever motor brand you want to use. Example: for the Wanderers, 40k rpm is the absolute max rpm. 80% of that is 32k rpm.

Then, just divide the working rpm by the voltage to get the approximate kv value. Just pick a motor of the size you figured earlier, with the kv value you just figured (preferably using the loaded kv value if possible).

Then, taking into account of all the various gear ratios (diff, tranny, etc) gear up/down for the speed you want, while keeping the motor/ESC/battery temps at a decent value.
