Remember flying low to the ground makes engine run richer. Looks like you have a winner. Thought about you with all the shut down of activities. The local race tracks are getting back in action, but I guess the state and county fairs are a no go. Too bad the politicians don't have to foot the bill out of their pocket instead of the tax payers. Any way glad to see you are still with us. D>K

NEVER ever break in a PA AAC engine or most any other ABC AAC engine in by running it slow and rich in the air, You can damage the engine, kill the rod, and you will NOT properly break-in the piston sleeve fit, These type engines require you getting them up to operating temp for the parts inside to grow to the size it needs to, to be properly seated and get a stable engine
Regards

Duly noted for future.
Seems to be flying well for me. Maybe I got lucky. I did have a good bit of ground break in time on it. Enjoying it.
Ran it too rich a few time and too lean a few times but have a good setting now.
5.2-ish lap times. Seems slow but great tension on the lines and goes through all stunts without a hitch
