Great. good price too

But , F-30A is available at ~$9 and flash it yourself...so atleast you can save $4 for an ESC , provided you own a Atmel programmer and have knowledge about electronics.

still, ready to fly is always better.

I hope the other ESCs which are going to be launched support a 6S battery :')

F-30A's and reflashing would be a better option. Buying a atmel programmer would be much cheaper as it will come inside 400-500 rs and you can flash many esc's with it.
