Quote from: sturgm on Wednesday,December 19, 2012, 19:30:43 All rotary powered vehicles rely on the gyroscopic action of the rotor itself to contribute to stability. A great example of this effect can be seen with the child';s toy gyro. Which when spun up by the cordcan sit at 90 deg from the vertical on the top of a bottle, defying gravity and if pushed will ';fight'; backto keep its position.If the mass of the rotating part were to be decreased then the rotor was loose some of its effect andthus would become less stable and produce less ';fight';.If this knowledge is now applied to props it should be noticed that heavier props induce stability and lighterone decrease stability.The only upside is that the quad would become more nimble. Which would be an advantage to competition pilotsbut to your humble quad pilot it would appear as a more twitchy, slightly harder to control machine.

QuoteHowever, early prototypes suffered from poor performance, and latter prototypes required too much pilot work load, due to poor stability augmentation and limited control authority.

QuoteHi, Not really interested in the right/wrong issue . As you said earlier ';interesting discussion';
