| I have an HDX450se, I like it. My only complaints are the main blade spindle bends very easily (almost too easily)and no directions (the finless bob videos on another forum made the build go very easily, although I still had to modify the frames to accept the bearing holders). The HDX was my first mini e-heli, The motor that came with it it not that powerful, the speed control $uck$ ( I replaced it with the align 35A control and 430L motor. Now it flies with some authority). The carbon blades that came with the kit were ok, I replaced them with v-blades, it flies better with the v-blades. The HDX is a great bird, I believe the aluminum is made from some rather hard aluminum I forget what type ie: 7075-t6 something like that. I have almost 100 flights on my HDX with no problems. Other than my li-po's have puffed (that's what I get for buying some cheap li-po's) The HDX (at least the one I have and the way I set it up) needs a 190-200 gram battery to balance the heli. The t-rex 450sa only needed a 150-160 gram battery to get it in balance. I can tell you for sure the t-rex sa is rather fragile, a friend wrecked 2 in the last 2 weeks, they both required a re-kit (3 out of the 4 frame pieces were bent) On one wreck the boom hit first, the other was an inverted crash. Just about everything was damaged. (Cheaper to re-kit). I landed the HDX hard (blades never touched the ground) and only bent the main blade spindle.
Good luck choosing (it's a tough decision) |
