I saw Zims EXI heli and was impressed by it for the price I don't think you can go wrong and one of the guys in our LHS hobby shop who is a big Trex fan was even impressed with its flying (he did hate the Telebee gyro though).
Nearly everything excluding the frame is interchangeable between the Trex 450 and the EXI.
I would put it together the way Eaterof dog has his.
Zim as a lot of money to burn on toys and tends to see if he can solely support severa of our local LHS by himself.
