I <u>love</u> my 450 clone (Gootch Helios 450SE V2).  I also have read many times over how crappy the electronics are on the Blade 400.  My advice is the go for a clone such as mine or the KDS clones... my kit cost $86 without electronics; this way you can choose what servos, esc, motor, etc. you want and not be paying for something you don't want.  That is the beauty of buying a kit over an RTF or even PNP heli such as the Blade 400.  Hope this helps even though the last post on this thread was over 2 months ago.
