Default edge and edge-se whats the difference

anyone know what the difference is between
edge and edge se blades ? both sets I have are fbl versions.

also anyone know which blades on the market are known to be softer (more flexible). I am flying a ridged head want to try some more flexible blades as I have vibration problem.

EDGE SE 693/713 vs EDGE FBL 693/713 differ in weight and CG.
SEs are about 10g heavier with the CG 30mm further inboard.

EDGE SE 603 vs EDGE FBL 603 only differ in CG.
SEs have their CG about 40mm further inboard.

DH blades are softer. They're used on the Triabolo to partner with its rigid head.

Many thanks guys
Best I get some dh blades for my diabolo 600
It flys ok on the edge blades but gets the shakes spooled up on the ground, and shows high vibrations in the logs.

CG further out makes them more stable but less agile. Obviously vice versa for CG further in.

Sounds like they increased agility and then compensated for reduced stability by adding more weight. Net result more agility without loss of stability, just a bit more load on the drivetrain.

No, load on the drivetrain remains identical for the same AOA as the molds are exactly identical. If at all the load decreases a bit as you need less cyclic.

All blades from Fun-Key are similarly stiff.

Vibrations should not originate from stiff blades.

I read that stiff blades on a ridged head could trigger resonant vibes to go back through the heli rather then absorbed by the dampers.
my diabolo 600 got the shakes on the ground but is ok in the air with a high head gain, on a mini vbar and vcontrol @1400rpm head gain 95.
turn head gain down even a little and the heli shake in the air too
vibe logs show high vibrations, but nothing on the bench blades off. blades(edge)well balanced

NHP's - The DH's were for speed. NHP's are for the regular Triabolo and also used in the Diabolo.

A bit of hunting around - here's something that suggests non SE's are softer but you never know that CG might bite again

Riiiiight, totally forgot about that! EDGE FBL 693 and 713 utilize only one layer of prepreg per blade skin. Corresponding EDGE SE blades have two layers each. Increases weight and rigidity.
