i had both the BB and still have the ChinYak,the BB flies just ok and is very fragile.the ChinYak is one of the best 3dr's out there.nothing response to control inputs like the CY,but is also a little weak in the fuse, with the build up frame.it has a carbon fiber rod that runs the length of the fuse but still breaks just behind the canopy.the kit built ones have a foam fuse covered in balsa,those are the ones to have,if you can find one.
