What is the RPM I should expect from my DA-50 at idle. The engine has 6 gallons of gas thru it, it's now running a 23 X 8 NX prop at about 350 ft above sea level. Plane is a WH 300 extra. Belray H1R oil @ 50:1.

I set mine at 1200 rpm, I get 6400rpm with 23x8 mejzlik, 30% yak, 20ft.altitude, 5gal. on belray mc1 50:1
