Hoss, The directions for the Pitts stated that you should put the two machine screws in the holes at the top of the Cabane struts and then position over the pre-tapped holes. Don't tighten just make them snug. This way you won't get the alignment wrong when using the pre-tapped holes. The holes are simply a positioning point. If you mount the cabanes joined together, this will guide the wood screws in place as you finish tapping the holes with the larger screws. I started each screw and then turned a few turns and then went to the next screw. Did the same until I had them in place. This helps to avoid getting the alignment off. Check the directions for the CE. I would think G.P. would list this direction point as well for the CE. If the holes are way off then of course this won't help. I did this wrong on Pitts-1 and had to plug one of the holes with a dowel pin and epoxy and then re-tapped with a new hole. Always something.

Texas-3D - I was fortunate to have someone recommend Aerografixs to me as well. Roger is a really great guy and he does beautiful work. I'm confident you will be pleased. I used a True Turn with the DA 50 and had them cut the spinner back plate for the four mounting bolts. They also cut the slots to match the Menz 22 8 prop. I have read where guys do this on their own, but for the minimal charge it sure seemed worth it to have True Turn do this for me.
