I maidened my Thunder Tiger Lazy P-51 yesterday. I have an OS 25FX on it........I set up 50% low rates.....40% exponential in the ailerons and elevator. As I'm a beginner, I'm not ready for the high rates but I found this plane very easy to fly.....about the same as my Sig 4*. The Lazy P-51 has huge thick wings and a pretty much scale P-51 body. Its looks great in the air, will fly very slow, and is very stable.
