its identical to the trexsa. butt cheek to butt cheek. only differences are the the exi has full metal swash and washout plus metal head button. even the main gear on the exi is better than trex. it has the removeable screw type one way bearing hub.
I bought a few sets of Align skids for my MX-400 and HBKII's, these on the EXI-450 seem a little flimpsey compared to the Align sets I've been buying. HDX-450 skids are also awsome, and they look great.
