what max rpm are you getting with the different props?

With the 11X6 APC on the final tank leaned a bit more I saw 12.4K. I'll be testing it on a 13X6 APC next.

Back on post 50 I attached a full sheet of max RPMs with a range of props that we tested. You can look there if that's what you're looking for.

Running the ninth tank of fuel and I tried an APC 12.25X3.75 prop to get some RPM readings.

Still on the ninth tank. Changed over to an APC 13X6 prop and got some readings. I will run three more tanks using this prop and the 20:1 dino-oil mix. Then I'll switch over to 20:1 using Klotz oil and test fly the plane.

I have about 18 tanks through mine and she has been very reliable thus far. She starts easy, idles nicely and has pretty good power. I'm currently running a 13x6 prop in the new Meridian 70" and it has good power for the plane. So far so good!

just wondering how this compares in power to a 55ax....?

I seem to be getting higher static rpm's with a 13x6 than what would be seen on a 55ax. I hope to get it in the air to test it late next week as I'm waiting on a muffler manifold extension .

Sound great!! I have a 55ax in a GP Extra 300sp and apc 13x4 and it hovers but not very quick punch out tho. just let us know what you find out.

Have you tried the APC 12.25 X 3.75 prop ? That works quite well on 46-55's .

No I haven't... will have to give it a whirl. (no pun intended)
