I'd look at the E-Flite Alpha 450 Sport. Has some sport characteristics and some trainer characteristics. I have had a parkzone ultra mini T-28, parkzone t-28 and the Alpha 450. The Alpha is a MUCH easier plane to fly than the T-28 which is supposed to be easier than the Corsair. It also takes the same size battery as the hawk (but has a different plug). I love the plane and wish I had purchased it earlier.
I've never flown the hawk, so i can't really compare the two. If you can fly the 4 channel hawk, I'm guessing you can fly and land the Alpha 450 with out a someone to help you. As far as ruggedness, I don't know. Its so easy to fly, I've never had anything but lovely landings and flights.
