The search for the bacterial flagellum would take about 2^30000 trials or more depending on unseen complications. This would need to start from an organism that has never had one.
I am sticking with the assumption of 50% amino acid substitutions generating a null allele and a combined residue count of 300000. This is less than Behe’s number of 70%.
Now this number is not close to feasible so I would assume you disagree.
