I have about one dozen flights on the plane. It handles great in the air and tracks like it is on rails. I'm still finding that the landings can be challenging as I get the right combination of flaps and engine idle. My last flight was the first time I landed it without a head wind, and I found that the full flaps and air brakes are not enough to slow it down unless I get the big 17X10 prop idled down a bit. As I get the engine set better and get a few more flights on it I should be more comfortable with the landings.

As for the mods, I'm happy with everything I have done. The opening for engine cooling seems to be working well and the exit flap even held up through a belly landing the other day. My retract valve vibrated loose causing the gear to stay up. After the mods I made the controls are tight and I see no evidence of flutter even when wide open at 120 mph. I had to glue the williams bros. wheels onto the rims since one popped off during a landing, but other than that I have had no problems. I was a bit worried about how it would handle with full flaps deployed, but it seems to be fine.
