Luca,
What are you guys in Australia running on your 21 Hydros?
Is there many JAE-21's in Australia? So what are you guys
having the most success with? As you can see not a lot of
input from across the ocean? 1455's are working well here
in a variety of diameters depends on your motor and pipe
set up.
Aaron,
46 to 47 mm in diameter with a custom profile like
I have on a H-7 or 1450. We have just been doing lap
times and they are getting better. Remember the S-15
is based on a 1655, so the 1455 cut down is not really
that much propeller pitch wise. Try cutting some down
sometime and see how they work for you?
Thanks For Reading,
