Flaring when you are head high is too high. I see that a lot at the field with the new guys. Keep the nose slightly down like the previous posters said. The T28 will slow down and float. Descend and round out about a foot high to level flight then start the flare. If you want to show off, drag it flared like that about 3in high for a distance with the throttle( a headwind helps), then let off the elevator and cut the throttle to a main wheels landing or leave the elevator in and drag it on the mains. You are still learning about the planes responses, but having more fun doing it.
