   Post on Ideal Idle RPM in Avidfoxflyers General Hangar

   By SlyRoo, posted 17 Aug 2022

   Team,
    
   I am looking for what everyone has there idle rpm set to? I have the Rotax 670. I have been seeing 2200-2500, is this correct? Also do you have your throttle control set to when it is all the way pulled out it is set to this idle speed or do you have it set a little lower and just add a bit of throttle to bring rpm up.
    
   Thanks again.

   Post on Weight and Balance with new 670 in Avidfoxflyers General Hangar

   By SlyRoo, posted 9 Aug 2022

   Hey Guys,
   I just installed a 670 on my Avid MK IV HH. I am now doing a weight and balance. I just wanted to see what line do you use to level the plane. Do you use the bottom of the door? I have the Excel file and my old WB from builder. Also what do you use as the datum line, my paper work is showing the leading edge. Just want to confirm. Also any info on doing this process would be appreciated. thanks.
