My experience with WarpQuad was the exact opposite. The instructions are the most comprehensive I have yet seen and the testing (video of the tests even!) was extreme. Twitch frames were almost custom made to order. Instructions were slim but worked and Twitch was just awesome.
I would be surprised if the Alien is not VERY well thought out, tested, and well supported.
Notice how the booms come together in the center to make a solid core of carbon fiber? It puts more of the weight in the center and makes the copter insanely hard to break down the middle. This design is the result of testing, flying, and walking the walk of shame, not computer models and sales projections.
The Vortex looks pretty complicated, expensive and prone to be eaten by chain link. I dunno but it just looks fragile to me. My WarpQuad is NOT fragile. It is simple and elegant and flies like nothing else I know. It can take a beating. In a WarpQuad test video, Soma holds his copter by a boom and smacks the copter into the ground repeatedly trying to break it. I think the Vortex would be in little bitty pieces.
I have been waiting. The Blackout and other flying bricks just don't do it for me. This machine is right sexy and will make a nice addition to my hangar.
If I get my hands on one, you can be sure I will do a build of it right here. If I can make it fly, any butthead can make it fly.
