Couldn't tell you? my wattmeter isn't set up for that small of a plane. You need to be conscious of your full burst, it will only go vertical for a 100 feet and then it runs out of steam but you can hover it for a good 20 seconds and still Pulls out fine. Reminds me of the early days of 3D.
Perfect for indoor. I even had a 5 mile an hour breeze today and it wasn't an issue on 2s.
