hi, i have this plane with a Brison 2.4. weight came up at 12.5lbs. power is what you will call "unlimited" but the plane is too heavy for its size. At first i thought it was light on the scale but when i flew it. she snaps pretty hard. harriers are tough cuz of the weight issue. if you wanna hover. you would have to gently bring it into a position where it will hover or she will snap out.
