Thats good to hear, what i'm doing will probably be almost perfect. The only thing that concerns me a little is the span.
I'm using 2 sheets of 1/4x6x36 balsa to cut a profile fuselage out of (looks similar to sud-o-khoi with large side area) between them i will sandwhich 1/4 square balsa sticks. Having that space between the 2 sheets should add a lot of strength because in order for the fuse to break, the sheets will now have to stretch and compress more.
It's going to have a 35" span (similar to the pen knife, which i'm sort of using as a starting point for dimensions) and about a 13" chord (including the 3" wide flat ailerons). That gives... 455 sq. in.
I used profili to export a slightly modified NACA 0018 airfoil into autocad and from there i added spar notches and cuts for LE and TE stock, then printed out templates. I cut the ribs out last night. Using 1/8" balsa for them.
For the dimensional relationships between all the different part i've just been looking at other FF planes and using the T.L.A.R. method. This is my first attempt at either design or scratch building. It may be slightly overbuilt, if so, i figure the worst that can happen is it's a little heavy and instead of being a good FF plane it'll just be a cheap small sport plane.
Here's the stats i've determined so far:
Span: 35
length: 39
Airfoil: NACA 0018 (slightly modified to move "Fat" part a little further forward)
Wing centerline on the thrust line, stab centerline 7/8" above
Stab LE 12" behind aileron TE
Stab span 16"
Fin height: 10" (from bottom of fuse
Wing LE 5" from front of fuse.
If anything looks terribly wrong there, please let me know. The main reason the span is 35" is because that way i can use single pieces of 36" stock for LE, TE, spars, etc. and because thats about what the Pen Knife is (36"). As for the fuse length, first i figured it should be the same as the wingspan, but the TLAR was telling me there just wasn't enough space between the aileron TE and the stab LE so i added 4" to the fuse in that space to come up with the 39" total length.
I think i'll draw up the fuse on Autocad after i finish this post. I'll try to put it up here so maybe i can get somebody to tell me that it'll never fly
before i build it
