Correct me if I'm wrong but the Blade 400 is a 400 class machine right along side the Trex...yes no? With the support I have with Eflite products at my LHS I would probably move to it over a Trex. However my LHS does have a wall of Trex parts too. Unfortunately no heli guru on staff so your kinda on your own. I'm thinking the Blade 400 perfect for someone to move into has everything right out of the box.
