The next heli, part 1

The Cypher 3D is nearly built and the maiden flight is looming large.  Assuming everything goes to plan, I now have to consider what comes next. Do I move to a larger airframe or stick with mid-range?  Do I move from an electric to a petrol engine? This opens the batteries versus nitro debate. For loops, rolls, inverted flight and other intricate stunts, I'm going to need a much more powerful model, with a better build quality. I'll need more channels with more programming functionality.  A programmable ESC.  A heading hold gyro.  Better servos.  Carbon fibre blades. A better pilot.

So much to consider...
