That's for sure! When you hit a wall you will know. :-)

So you mean there should be no additional inertia then? Ok, not from
accelerating the blades (clever concept, never thought about that). But
doesn't the engine (turbine) need to increase its power when the angle
is changed to lift the helicopter? And then we would have the inertia
again, wouldn't we?

Fortunately my helicopter will live in a 2D world. :-)

I think the blades also should work more effective when the helicopter
moves faster. There are a few helicopters that can fly loopings and AFAIK
some do that without wings. And they always seem to do that at high
speed, so speed must have some influence on the lifting rate.

Correct me, if I am wrong.

Have fun!
