Hi People

The Glasair has finally left the ground and had a successful first flight.
I’ve attached a graph of the data. OAT was 63F
I was really very pleased given our smallish 20in2 coolant inlet area and <9in2 oil inlet area for ~190hp.
The temps are a bit hot (~220F) but we didn’t go beyond 110 knots. I suspect when we get the airspeed up above 150knots into her nose we’ll see some improvement.
My hunch is we might have too much pressure in the cowl. The exit air area is approx. 30in2.

Appreciate any of your thoughts from the first flight data.

Cheers
