Hi.
I'm using SAB 710mm Jason blades on my R90.
I'm pretty happy with them but i would like to try the V-blades some time. Haven't tried the 700mm.

I am running either SAB or TT 710's on both my 90's, I run an 8.27 gear ratio to get the motor "into the pipe" at 1850HS. Running a YS91/MP2 and soon an OS91CSpecPS/MP2 on the other.. Cannot load them unless I botch it real bad. Running 11/-11 pitch and 7.5 cyclic. If this configuration gets loaded up either the engine is not at peak power and into the pipe, maybe rich, the setup is wrong, or poor collective management.

The SAB's are weighted differently for cord CG and will give you extremely nice autos compared to the TT's, I would like to try other blades so I have more comparisons. During flight and maneuvers I cannot tell a difference between the blades, just autos forever on SAB's

Just my .02

I have tried both the Jason baldes 710 mm and v2 blade 690mm.

Jason blades 170gram
V2 baldes 187,2gram

It´s much easier to bog the engine with the v blades but you also get a little more snap... In autos a prefere the v blades because the have a little more hangtime, but thats maby thanks to the weight diffrence!?

I think the sab blade are a better blade, much smoother and the helicopter seems to sit better, but for the persons that only fly hard 3d and want a blade with a little more snap.. Buy the V blades.

It´s hard to explane the diffrence between these two blades.. I like them both very much... If you have the money, buy both!, you want be dissapointed.
