Well, I finally got the bird off the ground.
I made 2 flights today. The 1st was 1/2 hr long. I had high cylinder temps & a very slight oil leak. I found out where the leak was from, Cyl #1 pushrod tube seals. They weren't seated in far enough. I tapped them in & the leak is fixed, confirmed by my 2nd flight. Also made the bottom cowl exhaust opening a little larger but the 2nd flight still showed high cylinder temps. Probably need to make a front centerline baffle as others have. Noticed that the engine baffles that curve underneath the cylinders, connected by the springs, are too long & don't allow enough air to pass thru the bottom of the cylinders. Anyone have any other ideas ?

VERY short takeoff roll. Don't know the distance yet. Will get that later when all the more important problems have been solved.

Too Kool. A big congrats to you.... Glad you have got the bird in the air. I am just guessing here since my 801 is water cooled but the 801 flies at such a slow airspeed I bet the reduced airflow diminishes your engine cooling as bad as it does mine. Ya got to love the very short takeoff rolls as compared to all the other planes you have flown. A quick caution,, don't park the plane into a strong wind with very little fuel and then get out. It will try to lift off.... Congrats again Rich..

Congratulations on your achievement.

My 601 is getting bigger day after day, and I think it would be finished next year !!

Take care
