So last year flying my Inspire in Sportsman I never gave a thought to "setting an idle". Then young Joseph Sczur flew my plane after the competition one day and suggested "setting an idle" plus I noticed several other "pros" doing it at the last competition I attended. So I started "setting an idle" as well. Then recently someone mentioned that you want to set enough idle to keep some airflow over the rudder during a stall turn, and now with the help of my new "fancy-shmancy" Castle HV80 I'm getting prop data for every flight and I see that my idle is roughly 800RPM.

So whats the science behind what you set? Are there pros and cons? Can I set to high of an idle? What about to little, does it do anything positive?

Anyways, just wondering what the "big boys" do


Thanks as always,



Joe
