Presenting the BB J3 Cub. This plane was my entry in the BB Tribute Contest, but was not finished by the dead line. In fact it has taken me a 3 months since then, because of more pressing issues. The plane flys better than my 42" RET BB, I built this one with ailerons, my first. I have a vid of it flying for about a minute before the batteries ran out of juice and I hit a tree. Remember to always charge your batteries before you go fly.

Here is the vidio of the maiden flight.
