I have flown a corsair and well it is quite a handfull and I overpowered it. It definatly needed it. Meaning that it was a GP arf and it was very heavy and it needed all the power it could get to motivate. But I plan on getting one someday, probly the H9. I have flown the Exrta 300. I love the way it handles. If you have low wing experiance then I would go with the 300. Mine was a kit from GP 40 size and I love it. Lands great, and flys like it is on rails.
