I was wondering if anyone could help me out on this one. One of my buddies offered to supply me with the spruce for my KR2S project, but all he has is 2X6X8 stock and it will have to be split into smaller pieces. Since I haven't got my plans YET, one of my fellow builders was kind enough to let me have a look at the spruce list so I can figure out how many I will need. Maybe my arithmetic's are a bit rusty, but when I was done adding up, the numbers didn't look right at all (they would look great I were counting stars). I would just need to know how many pieces of 2X6X8 I would need to suffice for the KR2S so we can get it shipped all at once rather than in small instalments. Thank you, Florin florinpi@home.com ---------------------------------------------------------------------- Subject: Re: Please comment!

Perry >> Perry, in this case increasing the size of the horizontal stab will do nothing but increase the stability of the airplane. I don't have the charts in front of me but the plan built area of the horizontal stab doesn't even approach the bottom of the chart. A good number to start with is add about 4-5 inches to each tip of the stab. If you want to leave the elevator the same size then do what Mike and Troy did and allow the horizontal tip to extend aft to meet the trailing edge of the elevator. This is an area where any addition size does matter...............
