To better show the outline of the new windshild (for the photo) I put tape around the edge. If you compare the windshild with the tape to the front windshild without the tape you can see the change I made. I'm sure someone else can come up with a better design but it works for me. The front windshild (old design) was 6" taller than the front of the cockpit and the new windshild is 9.5" above the cockpit. Tonight I'll be making a new windshild for the front. The white vertical lines you can see in the new windshild is where I bent each side about 30 degrees to bend around the cockpit. The front windshild is also bent but you can't see the lines in this photo. Hopes this helpsGene________________________________________________________________________________

This is a second and last photo of the windshild. This time without the tape and it may make it easier to understand what I'm trying to explain.Gene________________________________________________________________________________Date: Sun, 2 Nov 2008 18:38:07 -0400

GeneI also have an over sized windshield and the wind goes right over me making it confortable and quiet.One very nice thing on the Piet design, is that you can trim out the balance using the flying wires on the horiz stab. I made a couple of changes recently which left my plane a little nose heavy at cruise. I let off one turn on the front leading wires and tightened one turn on the bottom. Now it flies perfectly.It was also a beautiful day in NW Wisc. It's weird flying over some of the local snow Ski areas which are open any I was in a light jacket. Soon the lakes will be frozen which will make for some exciting flying at 1-3 ft.Dick N.----- Original Message -----

Jeff. Good catch! Yes I have noticed a small amount of tail heavyness but I believe once I make and install the front windshild that it will do away with it (I use to fly without a front windshild and experienced the same tail heavyness until I installed the front windshild). It wasn't much, but enough so that N502R was not flying hands off but instead wanted to climb a bit at cruise. I think that rather than have any effect on the fin, I'm getting the climb because the windshild slopes back and is installed near the trailing edge of the wing. I believe the air over the taller sloping windshild is pushing down on the airplane behind the CG (sort of like holding your arm out the side causing the airplane to turn in that direction. The front windshild, on the other hand, is located forward of the CG and I believe the wind pushing down on it will even things out. Even if the installation of the taller front windshild does not return it to hands off flying, I will leave them on as the flying is so much more enjoyable in cool weather with the taller windshild and the change is so small. I did not notice any other effect. I have flown with it for two hours, hard climb, fast descent, steep turns and cruise plus slow flight and was unable to detect anyother area where there was a change in the flight characteristics.Gene----- Original Message -----

Gene, When I bought Felix the GN-1 the seller gave me an extra windshield that was about10" tall. He said he replaced it with a smaller windshield because it blankedout the rudder and it scared him so he took it off. I flew the plane all summer2007 with the short windshield. About this time last year it started toget cold so I cut down the tall windshield to 7 1/2" and installed it, much better.I probably have at least 50 hours on it with the taller windshield and cannot detect any rudder blanking. Another thing that really helps on colder days is a front cockpit cover, keepsthe cold air from coming up the pant legs.Skip----- Original Message -----

Jeff, this is the only side photo I have. I don't think the angle it's bent at is all that important as the windshild is flexable and can be formed around the cockpit. I used a brake to bend the windshild and I bent it somewhere around 30 to 45 degrees (just eyeballed it). If you want more photos let me know and I'll send them directly to you.Skip, glad to hear that the cockpit cover helped cut down the draft. I've been considering making one to see if it would. Now I know and I'll be making one for sure.Dick, I'm really envious. Wish Tennessee had some real winter with frozen lakes to land on. I've spent most of my life in Alaska and do miss a "real" winter. Winter flying is like tail wheel flying. If you haven't done it, you've miss out on the best part of flying. The info on adjusting the flying wires is very much appreciated and if installing the front windshild does not take care of the tail heavyness, I'll adjust them.Gene________________________________________________________________________________Date: Mon, 3 Nov 2008 06:59:21 -0800 (PST)
