Subject: [FlyRotary] First flight
RV-4 #2366, tail # N52BT made it's first
flight today. It didn't make enough power , so only one lap of the traffic
pattern was made before the pilot landed it. From a standpoint of flying
qualities, it was just like any other RV-4s- no out of trim conditions or other
bad habits. No note was made of MP at WOT, either on the ground or in the air,
that's first on the agenda tomorrow.
But-- I only revved up to 4800 rpm on the
downwind, so the flight was terminated. I have gotten 5500 on the ground with
the cowl removed, which means the air cleaner was not in use. I am using a Fram
paper filter, 6 inches by 14 inches. I think I am getting a big restriction
from it, so I will remove it and try some ground runs. I also think I'm running
way too rich, about 34- 7/8s up the scale on my EM2.
The good news is that neither the oil or
coolant temps got over 160 the whole time, and the plane was waiting on the
ground for around 15 minutes due to traffic in the pattern prior to
the flight.
So, I'm happy about the flight, but now
must find out why I'm not making more umph.
