Jay, I have a 415 with the O-200 and a 69-50 prop. Climb is great. I cruise at 2500rpm (max recommended is 2525rpm) and burn 5.2ghp down low, and as low as 4.2 up above 10k. I see about 90kts or 104 mph. With the alon, the 69-48 prop will be very under pitched. You will climb well but won't be able to take advantage of the alon's lesser drag. The alon's have no problems cruising at 115mph, but you will need a different prop to hit those speeds. With your prop you should expect to see about 100-105 mph @ 2525rpm. Good luck Dan N93805

I am curious about what sort of performance to expect from this plane. It has the O-200 with a McCauley 69-48 prop. If any of you are flying something similar I would enjoy hearing about cruise speeds, climb rates, fuel burn, etc. Also, I have a set of wheel pants that I have not installed yet. Would like to have opinions as to whether they are beneficial when compared to the extra weight. Thanks! Jay
