While I salute the flying skill of these modelers...given enough power, even a brick will fly or hover.
I guess I've just never understood the attraction of these 3-D models...if you want to fly vertically and hang on the prop, get a helicopter.
The latest take on 3-D flying involves controlable-pitch and reversable-pitch propellors. Instead of hanging from the prop, this new tech allows the model to stand on the prop, or literally fly backwards.
