I'm the one who got this swisscheesing idea and found it useful.

Why is this good for heli performance? It takes away the dead weight from the right place. The micro FP helis are extremely unstable because of too high center of gravity. The head structure and the rotor blades are utterly oversized compared to the bigger birds or real helis. The rotor on a real heli never makes up more than 10% of total weight. The micro helis have more than 1/4 weight there. Reducing head weight to lower CG is way to go to improve performance. That's why we are seeing smaller blades, super light CF blades, flybarless head on high end birds. Being lighter, the momentum issue is easily solved by added weight to tip.

As for blade deforming, the plastics flex anyway. As long as you don't overdrill it won't make a difference. Yes you have to do it right. Moreover, a frame structure always keeps better shape than a solid piece, more so with plastics. Wings and blades we see in use in real world are made of a frame covered with skin. They are not only lighter but also more robust.

Otherwise, I'm as strong as you an advocate of flying stock. I have always flown stock and gained experience from there. My Aerohawk is all stock but was made superefficient after sisscheesing and 5-10% cut down. It can hover more than 12 min on one pack NiMh battery. I also agree that newbies should learn to fly before considering any modification including this one.
