That 1409 is a rather small motor. If you want more power, i would take a larger motor. Why use the HC160, if the current is a concern? it has got the same currenthandling as the L160.
Perhaps you can take the HC160 and take a lower kv motor (maybe even slightly bigger) and use it on a higher voltage, in order to get the currentdraw down.
The only reason I mentioned that setup is because there is one on ebay right now. My main concearn though is whether a sensored system will be able to perform well in an 8th scale. The main reason I sold the 1409/1.5 and L160rc is because at the time (4-5 years ago) everyone said that a sensored system just wasn't the way to go for a high current fast emaxx.
So heres the question I should have asked first: Are there any drawbacks/advantages in going with a sensored system over a sensorless? If I remember correctly the reason I was told to ditch sensored before years ago was because of max rpm limit or some problem at high rpm.
