brushless twin detonator?

[viking252]

Hi

I just bought a twin detonator and i thought about going brushless ...

I was thinking of getting a pair of feigao 540 8s together with a
warrior 9920 controller and a 3 cell lipo battery.
Is this set up ok or am i totally on the wrong track?

I am new to the world of brushless , so i would appriciate, any help, info or advise on wich setup to get.
