My Bean had a Black Widow and the first honest to goodness good looking finish I had done in red, white and blue. Up until that time I had never even flown a plane inverted until a more experienced fllyer took it in hand and wrung it right out. Iwas never that good with it, but *** sure helped me move up the ladder to the larger stuff.
Ihad noticed the resemblence to the Shoestring and will likely build another even if Ihave to "eyeball engineer" it since I'm too cheap to pay "market" (ahem) for it. Ican imagine it must have been quite the handful with that .09!
