I now have 14 flyable planes (and I fly'em all). One has an LA .40 which I have found to be a very reliable user friendly engines of all. I also have 2 Super Tigre .40 engines which are also very easy starting and trouble free. They also have a heck of a lot more power and haul much larger planes with good authority. For the same or less than the LA I vote for the Super Tigre hands down.
