OK Addy, I don't have the A2A Cub - it's on the shop list! - nor the Scout. However, I do have crash detection turned off, though at the point of "water contact" FSX should throw the aeroplane back into the air automatically, and I don't get that. I have a couple of images in an archive of the ultralight water skimming. I will try and dig them out, and get some of a cub. I'll post them here sometime next week.
Have you asked the "cofig" question on the Scout support forum?
