Hi all i just joined,im new to this hobby just building a 450 trex clone following tonys videos so far so good,i also going to build a hk 500gt i have most parts just waiting for a few more bits.A few years ago i bought an e smart 550 fully upgraded parts i never flew it (i cant fly yet) i believe you cant get parts for it anymore or are hard to find just wondering could parts of the heli be transferred onto a trex 550 clone thanks
