I installed the Rosen visors several years ago and experienced similar difficulties. As I recall the stiffeners were not even close to the proper size, shape or form requiring a couple of hours of grinding, bending, trial fit and repeat until I had a servicable arrangement. I found the visors to be an effective sun block but found their two claims to fame, transparency and adjustability, more hype than substance. You wouldn't want to bet your life on spotting conflicting traffic while trying to see through them and although they are somewhat adjustable the sun is somehow always just out of their range. On the wingtip installation; I assume you or your mechanic have strap duplicators but if not they are a slick little tool for match drilling the new tips to the existing nut plates that you definitely want to employ.

Wing tips w/ winglets are from Owen Bell at Aviation Enterprises
www.aviationenterprises.us I will post some more photos. We got them ready to drill the new holes tonight. I am not sure about the strap duplicator but the instructions that Owen has calls out a 2 inch wide .020 aluminum to duplicate the holes in the original tips and transfer to the new tips. Should work fine, I'll find out tomorrow. I have the Horton Stol and this should only enhance the performance and stability of that kit. Flying the Monster with these wing tips was amazing, especially on landing. They also claim to increase cruise speed at higher altitudes, we'll see. Thanks for all the confidence on the Rosen's Steve. :-) I hope I like them. After spending that much money do I have a choice?

Herb has been busy, and gone, so I know he hasn't seen any progress. However, there has been some. I have been working with his A&P/IA, and we actually have gotten a few things finished. The new winglets are on. These really are huge, but very light. They are made out of carbon fiber. There is a lot of matching holes, to make sure they line up, but they are now on.
As part of the upgrade, Herb got new LED position lights, and brighter strobes. Or maybe his old ones were just weak  In any event, the position lights use clear lenses, and rely on the LED to give the correct coloring.We also got the boom fairings on. These are also carbon fiber, and huge. There is quit a bit of work involved with getting these in exactly the correct position. Then fastened. We observed that in some places the boom fairing edges would lay up against a rivet. Herb talked to Owen Bell, and he gave advice on how to remedy that. The end result is very clean. With the comments on the Skymaster that went down in the Artic, Herb got cold weather inlet restrictors, and these are mounted. As well as insulating the crankcase ventilation line. One of the pieces that connects the stut to the wing (strut fairing) was cracked, and generally in poor shape, so that has been replaced. Getting the old one off was easy. Getting the new one on, was very difficult. We still have to mount the window in the door, and a couple other things, but we are close.
