This is a really nice video filmed by my friend Audun Thinn. It shows the first flight of the blue Lorenz Laser, powered by the OS 200 FS with an added Perry pump. The exhaust is a Hatori #824 pipe. The engine runs rough and rich and finally dies but the plane lands safely. The 200 failed to perform as hoped after break-in and was sold in July 2009, will be replaced very soon by a YS 1.60 DZ. A larger version of the video can be found on Youtube
