I had a u-can-do and lost it in the sun[8D[>:] but found it in the ground[:@] I replaced it with the Harrier and wish I had gotten another u-can-do. I powered both with the same engine, OS50SX (fyi both planes needed more). I felt more comfortable with the u-can-do than I do with the Harrier. I had to change the covering on the Harrier on the bottom wing so I could tell the difference. The clear covering is nice but I like to have the top and bottom very different. Just much easier to see.
