bird, It was directed at more than just you, I didn't feel like listing all the people that think the FW's are functional or should be. And its not about being right or winning a 'pissing' contest, its about education and putting out the right information. If you guys really want functional FW's, you are going to need to reinforce the ribs with plywood, screw plywood blocks to the reinforced ribs, then you will need probably 4-40 wire and some heavy duty clevis'.
How is a wing failure going to cause the plane to hit someone or fly into the pits if its being flown in the correct area of the field? We aren't talking radio failure. Some of your original comments point out structural failure and hitting people.
As for the crimps, no the wire will not come completely out but it will pull on the loop pulling the clevis against the crimp effectively lengthening the wire and now your saved wing is flopping in the breeze making the plane uncontrollable. I have pulled the wire through and when I applied more squeeze to the tube, it either split or got a stress fracture.
As for the engine coming lose, read through some of the other Pitts threads, several people have had to reinforce the bulkhead, granted they had bigger than needed engines, but the stress caused problems. I was doing maintenance on mine and just happened to notice that the front sides of the fuse moved when touched. Found that half the balsa had come unglued from the bulkhead and one of the hardwood longerons had come unglued from the bulkhead. Another guy at the field notice the covering on his didn't look right, when he got the cowl off he found that the bulkhead was only being held on by the four hardwood longerons. SO check your bulkhead everyone.

BATTER UP!
