A mad brushless setup help

[captain harlock]

4s lipos with a 9920( cheaper than 12020 and capable of handling the 1920/5 easily) would easily get you to the 80 realm.

Yes, the 1930 will put even more power and speed than the 1920, but it will also add so much strain upon the transmission of your car to the point where you will find that all of the cvds are either bent or broken and the gears will quite possibly melt with the excessive power of that nasty motor.

A 1920/4-5 is more than enough for super insane speed. You make your choice, now, and you must bear the outcomings.
