Dan,
I hate to say it but I have not flown a Club 40 plane with an Evolution 46NX on it. I have flown a 424 plane with one. I have run the 46NX on the bench only for prop testing.
I can't speak for what the other guys have been doing with props, but what I found was that with my APC 7.8x6C props that I use for break-in, the 46NX was only 200-300 above the best TT PRO 40 I have left. With an APC 9x6, my TT PRO 40 would turn 16,800 to 16,900 and the 46NX could do 17,200 to 17,400 really peaked. I did not have my Fromeco TNC tach at that time.
I did tests with heavier props and the 46NX could pull a 10x7 to more than 1000 rpm's over a TT PRO 40 trying to turn it. With our heavier and draggier Club 40 planes, the prop makes a big difference because of the additional torque that the 46NX seems to have.
As I said, the Evolution 46NX is still legal for Club 40 Gold. The .40 c.i. limit with no exceptions applies to Club 40 Silver.
