Hi Scott........ Hm..........Difficult question to answer. I would have need both planes side by side and then fly them to provide an accurate answer. Here is what I understand from my perspective. Keep in mid I know much more about the Pitts than I do the Eagle.

I think your latter comment is probably more accurate. Meaning, they basically took the same airframe and changed the covering. However, the Eagle fuse is a bit longer, which may help with the ground looping tendency on the Pitts. The cabbane and interplane struts are the same. G.P. sent out new cabbane and IP- strut brackets at no charge to Pitts owners who requested them. I think this is standard with the Eagle. In the earlier Pitts model these had a tendency to break, but all kits now come with the upgrade. The cowling on the Eagle comes with a cowling ring which is an improvement. I think they beefed up the mounting box and the firewall on the Eagle to be more accommodating for gassers, though on the Pitts this is easily resolved with pinning, tirstock and fiberglassing. Like I said, when I lost Pitts-I, including the engine, the firewall remained intact. Also, the newer model Pitts now have better ply on the mounting box firewall, which may be what they are now using on the Eagle. Regardless, I still reinforced mine just to be sure.

As for flying, from what I have read on the Eagle and experienced on the Pitts, I think they are pretty similar. Both are easy once in the air, but can be a handful on the ground. Rudder and throttle application are important on both. Landing requires power to the ground.

Maybe someone else can provide more info on this though this is off the topic for the original thread. There are several good threads on the Eagle for those interested. Here is one.
