I showed the nitro side some love by reposting an article I read about glow plugs so I figured Id do the same thing and show the Electric side some love this time
One thing that I would like to add to this is that when they talk about electric motors that are higher RPM the article keeps saying that the tradeoff is shorter battery life. That may be true but the more important trade off that they don't even mention is that of torque. The higher RPM the motor is the less torque it will have. With that in mind Higher RPM doesn't always mean faster either. What I mean by that is this. Lats say you have a 3800kv motor and a 5400kv motor. The 5400kv motor is higher RPM so given that the gearing does not change then yes a 5400kv motor would be faster than a 3800kv motor. However, a 3800kv motor has more torque and because of that you can run a bigger pinion thereby turning that extra torque into speed and sometimes you will actually be better off by choosing this option over simply buying a motor with higher KV ratings (or lower Turn ratings).
