> We re engined our Skyhawk with a 180 hp upgrade. It required a test fly off that I think was 15 hours, but may have been more. I spent the first 2 circuits in very close to the field and the next 3 hours circling over the field at varying altitudes above the pattern making power and mixture setting changes till we could be sure nothing would go away. After that we were a little more comfortable with putting a bit more space in between turns.

Yes, that is also the operating procedures which FAA require, anytime you get an Amateur-Homebuilt Inspected. I was restricted for first test flights for a few hours in the pattern, as you said.
I sent this information and it didn't appear on the Group Website, when Gary was "feeling his Censorship oats"
I'll send a copy of this one DIRECTLY to you in case Gary is in a Censorship mood again.
