Stock gearing hits 40mph with a 20t pinion.
If one were to purchase a 1518, 1520, or 1717 motor, what would happen if the vehicle were geared to still hit its 40mph top speed while using the same battery?
Table: Motor and Pinion required to hit stock 40mph top speed.
1515 1Y 2200kv motor 20T pinion
1518 1Y 1800kv motor ~25T pinion
1520 1Y 1600kv motor ~28T pinion
1717 1580kv motor ~28T pinion
The three choices all have significantly more torque than the 1515, but will they be able to over come the added strain.
Will they pull more amps to do so?
Will they over heat?
Thanks

Hello
I didn't want to start a new thread in the same subject. I am wondering about the same question, but not from the theoretical point of view:
Did someone
actually try the 1717 or the 1518 geared up for about 40MPH with 4S 5000 mph (or so) Lipo in his truggy ? any conclusions? (amp draw, run time, temperatures ?)
Thanks
