GOOD combo for EFX

[KORN]

I have a EFX with the 8.45 ratio
I plan on using the YS91 with the new MP5 and a revmax
will this be a good match?
what size blades should I use?
What kind of blade is suited for the EVO90 head?
What head speed should I try with this combo?
Thanks for any help in advance

8.45 ratio with the YS is the perfect combo....Alot of guys are running 690mm blades on the EFX with great results.....i had an EFX but had the CX head...I was running 710mm blades with 95mm tails....some 690's would perform awesome and not load the motor quite as much plus you could up the tail blade size to 105's to get a little more tail authority.
Hope this helps.

Thanks for the info Vance ,
I think I will start with 690s then...
I read that the MP5 will like a higher rpm , do you think the muscle pipe is a good choice?
is the collet from the EVO90 kit the same for YS as OS
the Avant had a C-spec in it previously
Is there any issues I should avoid using a DX7 and Arizona setup on a Avant?
so many questions :oops:
