I ve got the h9 hellcat, p51, 150 size p47, and the 60 size p47 and the new spitfire, the retracts are a bit cheap but i have not had that much trouble with them. I think the 60 size p47 and the hellcat fly the best, but the new spitfire seems to like to snap on you in a fast tight turn, it happened to me on my maiden flight and scared the crap out of me, i thought i had lost her for sure, but i was able to recover., its did it several more times, but i fly them like a bat out of hell anyway, and i should fly them more scale like.....so thats probley why. Why dont you try the h9 p51 pts version, its a good little warbird, i have one of those all so and its one of my favorites......
