Hey Guys,
I have the Dynon D180. My rpm's randomly fluctuate down and back up while doing ground runs. I have also noticed that if I do a full power run up as soon as I get the rpm green arc, I will get as an example 5200 for full power. After reducing power to idle and then going back up I will be 100 rpms short of 5200. Maybe a heat issue? Reductions in power and back to full power may increase rpms +30. I don't believe that I'm actually losing 100 rpm's and that this is an indication issue. It mostly only happens at full power on the ground during run up. Cruise rpm's
have little fluctuation. Ignition checks are perfect. Oil temp and pressure perfect. CHT and EGT perfect. Run up done into the wind.
Any thoughts appreciated.
Thank you
