Hello all...been in the hobby a couple of years and although I've been on my own on this steep learning curve, I truly enjoy it! Within the past month I've completed my first two builds; a T-rex 450L Dominator and a T-rex 450 Pro DFC. The 450L is equipped with an AR7200BX and I went with the 3GX and sat on the Pro. Needless to say, I love both machines and am now comparing the flybarless units. Started out owning what seemed like every model Blade came out with. Happy flying!
