well Guy I love my 2 strokes been behind a 582 for more then 12 years and never had a failure , I have just bought another lightwing and will be powering it with enother 582 oil injection unit I think it depends on how u run the engine on start up and making shoure u warm them up probley ,all those video are true ultralight aircraft in the early days from the looks I would not be game to fly any single engine aircraft over some of that terraian but people do ,even todays four bangers do let u down and most times its when u take the risk of flying over tiger country so for me it a warning to all be careful where u fly weather 2 or 4 banger murphys law will bite us when we list expected it , fly safe....
