New generation Esc to update?

I want to update esc in one copter that have old common ones but this stuff updates so fast that I find new ones every time when I open HKing page, many of them specialized to racers now, like this one:

How they performance on a 700kv 3s motors?, they have the advantage of lightweight, any disadvantage?


I wish to use with new Lihv 3s batts.

  • It should be no problem but be aware that there is no BEC. That means they will not power your controller and receiver. If you have a separate BEC that's fine.

    Why not buy one and test?
