I have a new ZDZ 50NG and I'm wondering what type of readings others are getting with this engine and other 50 class motors.
I have about 7 1/2 gallons thru mine. The last 2 1/2 was Amsoil 100 to 1 premix that I mixed at 40:1. I was informed by a fellow flier that this should have only been mixed at 100:1 because it has added additives to be able to run at this low oil content.

Anyways I'm turning a Menz s 22 x 10 at 6000 rpms. Seem really low to me, Thrust hp says I'm only getting about 24.5 static thrust.
