Below are Nick Maxwell's thoughts on the new Vblades. Nick has some exceptional flying skills and can appreciate the quality of these great flying blades.
Guys, I know this may sound a little biased but I'd love to give you my opinion and some facts on the new FBL VBlades. Vic stuck with his known wood core construction, but at the same time spiced it up a little more with a new technique in laying carbon and getting each set matched perfectly. He actually uses a laser balance technique that is just superior to any other balancing method being used in other brands on the market.
Elaborating a bit on the performance difference this kind of construction offers; a wood core opens up a lot of options that hollow or foam core blades simply can't achieve.
1) The blades are incredibly rigid, giving the FBL gyro system direct and precise control the entire length of the disk. Cyclic stops become more crisp, and collective authority for a given amount of collective pitch is increased.
2) Being the blade is a wood core, with added strength in the key areas, it's possible to make an, in total, lighter weight blade with yet a very stable CG. This is referring to span wise, and cord wise CG. The benefits of this are where VBlades really stand out. They are able to recover from a loaded situation very quickly, because of the light weight. Due to the construction it is possible to achieve a stable cord wise CG for less lead weight. This makes for a linear control feel, good stability in wind, still stable in fast collective/cyclic inputs, and very consistent stability through all RPM ranges.
Once again, do to the construction it is possible to have a stable spanwise CG as well. This means the total weight of the blade doesn't have to be over all so tip heavy to still get good stability during high speed flight, and hovering where most blades require extra weight in the tips to gain more rotational mass. While the general stability is the same for either technique the benefits of using a more stable overall blade CG (for a given length/width), for a lighter total weight over a purely tip heavy blade are the cyclic rates. It is possible to maintain the stability of a more tip heavy blade but still produce a linear, faster cyclic rate.
A few tests you can do for yourself to see the advantages of Vblades:
1) On a windy day, simply hover and check how the helicopter reacts to wind gusts. You'll notice the VBlades have less tendency to bounce vertically in the wind. This is also partly due to airfoil.
2) Enter a high speed roll and watch the nose position. You'll notice even with a lower FBL system gain, rolls are more axial and the nose is less "bouncy and disturbed" during rolls and other high speed inputs.
3) Hit the collective hard, and notice the disk stability (no angle change or cyclic kicks with aggressive input), and also notice the rates do not become sluggish is a loaded situation.
4) Intentionally load the rotor disk and see just how quickly it recovers to targeted RPM.
Hopefully that helps explain why VBlades use the techniques they do, and why it is safe to say, they are the most advanced blades on the market.
