SAB or V blades for T-Rex 450SE
I am about to get back into T-Rex. Between SAB and V, which is better...no...I mean...what is your recommendation? From my experience with the 90 ship. I like V over the Sab because of the quickness of V, but never try on T-Rex.

Thanks,

It really comes down to preference. From my testing, I like the sabs better than the V-blades for the T-rex. The v-blades are a bit too stiff, they kill headspeed in hard maneuevers, more so than the sabs. They also dont have as much catch. My blade of choice is KOK extreme composites. They've got a slimmer profile than the sabs and have a bit more catch as well. Its a matter of opinion based on the way you fly really.Timing is everything

fwiw..

Consider giving the Hyperion 325 carbons a try..More efficient than SAB, less pricy, and very stiff...Best I've tried...

I agree with drdot! I have flown with SAB and now hyperion blades. Hyperion blades are better in my opinion and cheaper than SAB.

After all this (imho) the V-Blades seem better than the KoK's to me now.
Wasp what motor are you using now? I have the Neu, I had to dial down the pitch afr a bit when using the V-Blades. The brakes you seek lay within the motor choice as my experience may be limited compaired to yours but the bugs are worked out now. I have the red o-rings from DeeTee and combined with the grip flip, control is no issue. Get rid of the stock align washout arms and grips for better quality and see if that cures your stopping power problem! The 4s Jazz/1107-2y/V-Blades combo is the MacDaddy for now!

Century just released Rotortechs. I would get those.

But to answer your question, Vblades if price isn't a factor.

And 3d Wasp.... "to stiff?!?" I don't think blades can be to stiff. Stiff is what you want. Inefficent might be what you mean.

I haven't flown V-blades, but SAB's are nice blades. However, I've since switched to Hyperions. The SABs are more stable and smoother in comparison but the Hyperions are definitely snappier.

They also dont have as much catch.
ive never in all of my aerodynamics experience heard the term "catch" used to describe a characteristic of an airfoil, rotor, or wing.

Folks just use different terms to indicate an airfoil's ability to work with the ether. With sailplanes, we used to talk about 'bite' as the quality the wing had, when considering an airfoils percent thickness, leading edge radius, and such, to carry energy through a high-speed turn. With a helicopter, some consider the 'catch' as the abilty to bite into the air under rapid pitch change, with the least amount of lost energy. A very small change in radius, chord, and/or thickness can truly effect the 'bite.'

couldn't of said it better myself boid! I think catch just means as if you shot the heli toward the ground with neg, and than "catch" it with positive pitch..

My buddy has Hyperions and I just got some of the non branded Hyperions from HeliDirect. They are identical in look, balance and weight...and they are $24 per pr.

The Hyperions are supposed to be the best balance of stability, agility and amp draw. The SAB's fly great but they are fat and pull more amps.

Thank you all for the info. I guess both SAB and V are good. I got some V to try it out this weekend and will get SAB to try out too.

Thanks again,

I believe so. Will only be flying 325 pro woodies though, as a friggen rock claimed the life of one of my KOK's early and I only have 1 good kok now
