Ok the 300kv 5320 out powers the 4330 310kv. The 5320 300kv pulls 3000watts and pushes the 19x8 cf 110gram prop 7850rpms. The 4330 310kv pulls 2740watts and pushes the same prop to 7540rpms. So ken tested the 4430 and said it was 310.58 kv.
So is both of my 5320s l had a higher kv than the 300? Yeah the 4330 is going to have to have a 20x8 prop to have the same power as the 5320. I asked for higher kv than the 5320 as a were looking for more power???

That makes sense...
Well if you go with the 20x8 here's what performance gains you may get: APC 20x8E Weight 112g Peak: 8167 RPM, 3123 watts, 69.8 amps, 44.8 volts Settled in: 7990 RPM, 2749 amps, 63.1 amps 43.6 volts Xoar 19x8 PJN Weight 54g Peak: 8330 RPM, 2855 watts, 63.8 amps, 44.8 volts Settled in: 8124 RPM, 2518 watts, 57.8 amps, 43.5 volts Xoar 20x8 PJN Weight 61g Peak: 8102 RPM, 3180 watts, 71.3 amps, 44.6 volts Settled in: 7947 RPM, 2863 amps, 65.5 amps, 43.7 volts Looks like close to 325350 watts more, should will make it slightly more powerful then the 5320 on the 19x8.

I'm sorry, I don't. The system that is in my 71" Slick is the same system that I took out of my 70" Slick when I sold it, and that was set up when the A606XS motors became available (I got the first one that went out to a customer), and that was a while back, and I didn't have a tach then...

I've just had three test flights on my 71 Slick with an APC 20x13E on my A606S on GensAce 60C 6S 2300s On the ground the current is 100 amps at full throttle. I like the hover pullout performance much better than that of an Xoar 21x10 or a Xoar 20x10. I also like the lower price and durability of the APC. The motor temp was fine, although the outside temp was 40 deg.

I assume you mean the A606XS, as, to the best of my knowledge Hacker doesn't make an A606S, That said, I was told by Mike Donovan at AeroModel that the A606XS would swing up to a 22" prop, (but I would think that a 22" prop on a 71" Slick might be a bit too much torque) so a 20X13 should be no problem at all.
