Wow!! Deans is very popular, i've always use Deans before, but this time i want to give a try to the 5.5 bullet. The only down side of this 5.5 that i can see first, is that's a pain to disconect, and realy hard to solder, because the connector have a fuc... hole in it's side and it's realy difficult to fill the conector with solder because i loose it by the hole.

I use 5.5 bullet between the motor and ESC too.
