There's something really odd about that frame. The tubes that come down in front of the engine look like they don't come back as far as they should and the tube that comes down around the back of the engine doesn't stop on that one, it comes down into the rear subframe area.
Is that a Kasea SkyHawk 150 with blaster plastics on it? They're VERY similar in size and shape but they're just a little different....
