As I'm starting to think about how to redesign the tail pieces, I'm first curious how the Antic geometry compares to the Jenny. Unfortunatly I only have a really small plans printed for a Jenny (1/47 scale!), but it should be enough for me to calculate lengths and areas. My goal in redesigning the tail pieces is to try to match the area of the stock Antic, or at least not be smaller. Just looking at the Jenny I can see that it has a much larger rudder than the stock Antic but the vertical stab is really small compared to the stock Antic. I think it's best that I try to match total area of the vertical fin rather than each piece. The horizontal stab and elevator look pretty close, but let's start looking at numbers:
Here are the dimensions of the Antic:
1/6 Scale Antic Antic Scaling Factor Antic Full Scale
Wingspan top (in) 56.75 6 341
Wingspan bottom (in) 56.75 6 341
Wing Area (sq in) 1133 36 40788
Fuse Length (in) 40 6 240
Total Length 44 6 264
Vertical Stab Area (sq in) 21.35 36 769
Rudder Area (sq in) 21.9 36 788
Horizontal Stab Area (sq in) 88 36 3168
Elevator Area (sq in) 40.8 36 1469


Here are the dimensions of the Jenny from the plans I found:
1/47 Scale Jenny Model Jenny Scaling Factor Jenny Scale
Wingspan top (in) 11 46.66 513
Wingspan bottom (in) 8.62 46.66 402
Wing Area (sq in) 24.22 2177.16 52731
Fuse Length (in) 6 46.66 280
Total Length 6.9375 46.66 324
Vertical Stab Area (sq in) 0.235 2177.16 512
Rudder Area (sq in) 0.815 2177.16 1774
Horizontal Stab Area (sq in) 1.914 2177.16 4167
Elevator Area (sq in) 1.5 2177.16 3266

So what I found from this is that the Jenny is a larger airplane so I need to scale it down a little. Here's the ratio of Antic to Jenny:
Antic to Jenny ratio
Wingspan top (in) 0.6634
Wingspan bottom (in) 0.8466
Wing Area (sq in) 0.8795
Fuse Length (in) 0.8573
Total Length 0.9031
Vertical Stab Area (sq in) 1.2257
Rudder Area (sq in) 0.6666
Horizontal Stab Area (sq in) 0.8719
Elevator Area (sq in) 0.6706

I'm thinking it is best to scale to wing area and fuse lenth, and luckly they are pretty close. This means I'm going to reduce the Jenny to 86% so it is closer to the Antic size wise. After scaling the Jenny to 86% and then further scaling it down to 1/6 scale, this is what I came up with:

1/6 scale 86% Jenny 1/6 Scale Antic
Wingspan top (in) 74 56.75
Wingspan bottom (in) 58 56.75
Wing Area (sq in) 1083 1133
Fuse Length (in) 40 40
Total Length 46 44
Vertical Stab Area (sq in) 11 21.35
Rudder Area (sq in) 36 21.9
Horizontal Stab Area (sq in) 86 88
Elevator Area (sq in) 67 40.8

Okay, this was a pain but I think it tells me that if I was to build Jenny style tail sections based on my 1/6 of 86% scale, my combined vertical stab and rudder would be slightly larger than the stock Antic and the horizontal stab would be about the same and the elevator would be more than 50% larger than the stock Antic. I could scale them down further I guess to get closer to the stock area, but I would like to see how this look so I'm going to draft up some plans based on this scaling. I'm not positive that what I'm doing is legit, so any comments are welcome. Attached is a tab delimited version of the Excel file I developed to do the calculations.

thanks,
