I have a strong DA150 on compact mufflers in mine, and a Sullivan Skywriter and 48 oz of smoke oil, and it in no way flyes heavy. No, it's not like a 129" TOC1/SD 40%Yak with a DA150, but it in no way feels heavy. As Kris said, it's an excellent IMAC plane, especailly with a 150 in the nose. Up lines are same speed as down lines, unlimited snaps on up lines, slows down well on down lines probably due to its rather thick airfoil.
