That's TWO things, and they were both mentioned before your post- they weren't forgotten! I sometimes bring planes that I am in the process of building to show my friends, and then let them check 'em out a week or so later to see them fly. I love kit building, and always end up swapping out the hardware that comes with the kits- I bring this stuff to the flying field to donate to some hapless soul who is in need of something quick to get back in the air.
