I have a DLE 55 on a Top Flite Tarheel Hal. It turned a 22x10 Xoar at about 7k on the ground. Flight performance was crisp and fast. A Beila 20x10x4 turns 6k on the ground. It flies scale-like if not a little sedate. The choice is one of taste, really. Check out a Youtube video by "Hans Thunderbolt" called "Maidenflight rc P-47DThunderbolt Top Flite."
Best regards.
