Mine is 32 lbs, G62, 24/8 plenty of power. Does loops just fine, need to push the nose down first, (scale). A pup needs a heavy motor up front, even with a G62, mine has about 2 or 3 lbs. of ballast (can't remember the exact amount). More power doesn't really do you much good, it will only go so fast with all the drag from 4 wings and all the flying wires. All the new engines are pretty lightweight, so more balance weight needed.
