Hello guys,
Iam planning to buy a hobbyking esc i.e,http://www.hobbyking.com/hobbyking/store/__15205__Hobby_King_30A_ESC_3A_UBEC.html
I want it for DT-750 motors,and i even asked some one suggestion.All I want to know is that,should  I need to flash it with simonk software,for multirotors?how should Ido that?.And besides I dont even know anything about programming.

As a cheaper alternative you can use this ESC. It will save you the hassles of programing, cutting the heat shrink, etc.

So i dont even need to flah it again?,is it good for multi rotors?

No need to flash these ESC and they are good quality ESCs.
