My Bad. I opened my big mouth without running the numbers first. Here are the #'s
The tail as bought from the previous owner. H/S is 827 sq in and the elev is 827 sq in. If I use this tail I will add 100 sq in to the HS to round the ends. The previous builder added lead shot in the elev to add a counterweight. Mine will be internal so this will be removed at the ends. This would remove 84 sq in of the elevator. The difference between the added area to the H/S and the removal of the weight from the elev will effectively be a 20% change in the ratio of the area of the H/S to the elevator area. Also my elev controls are going to be adjustable so I can increase the throw of the elevator if I need to. This is a small change in area and I believe the effects on controlling the plane will be positive. Most landing will be two wheelers with the speed brake deployed. Hope this helps Craig www.kr2seafury.com ________________________________ From: john pellegrino <pelle...@verizon.net> To: kr...@mylist.net Sent: Sun, October 17, 2010 2:24:10 PM Subject: KR> comments for Craig and his Seafury replica Hi Craig, I have been a fan of the KR2S for a long time. I joined this net to seriously consider building one. First of all, I am not an aeronautical engineer, I am a Pilot, but I have been an aviation fanatic since I was 7 and I am 70 now and I am always working on increasing my aviation knowledge. I am submitting this comment to you with the best of intentions for you to consider and maybe a discussion can develop where we all can learn more. You say you will only have about 75% of the horizontal tail area compared to a stock KR. You want to "tame the beast" but in my humble opinion you are going to make it worse. You are after a special Seafury look and that is really neat. It looks like you will probably increase the vertical stabilizer area and that will should be fine, but with the decreased horizontal area and the short moment arm of the KR, (at least compared to the Seafury) again IMHO, there is going to be stability issues, at least at lower speeds. I suspect you would need to fly your approach at a higher speed just to be able
