Energy used by blades / Blades for Gasser.

[HungryHippos]

I got told that some blades use more energy than others, for instance, when doing a elevator flip.

Sure the blade dimensions, shape, mass etc, along with many scientific and engineering factors could be bought up,

but

from a practical / hobby point of view, has anyone noticed if there is a difference between the various blades and energy used when doing things like flips, for the same blade length? , i.e. does the engine bog a bit less etc.

And if so, which blades?

The reason why I ask is, I am flying a gasser (GT15Hz) with 690 mm blades, and this engine does not afford much power.

However I am guessing the end results might be negligible.

Yepp, Helix bog less than RotorTech, RotorTech bog less than EDGE, EDGE bog less than Halo..

try rail blades, they seem to be great all around!

Rail blades increased my flying times on the Nitro by almost 1 minute. That says something!

Their was a fellow here, or on RR, a year or so ago, who used telemetry to measure the energy consumed by a number of top brands of 700 sized blades on his electric heli. He found that the RT blades consumed from 9% to 15% less power then the others he tested.
