Hi guys, I just finished mine. The 120 in a great choice. I would not go any bigger as you just don't need it. Take off is 3/4 power, flying aroung at a scale speed is just under half ( without full flaps). There is plenty there for those high cuban eight, and not a problem on landing either with static thrust. 1 pound to 1.5 extra lead in the nose. She lands in as little at 300' . Rotates is 450'. By far the best fly'n plane I personally have ever flew. This plane is awesome in the air and on the ground. DDennison feel free to call me if you have any questions. Welcome to the hog family.
