Default Speed plane

I am thinking about building a speed plane. I built an electric one and it does ok, I think its about 120 with a 4 cell lipo and 5X4.2 prop. I tried to fly it with a bigger pack and tore the wing off.
Now I want to build a .15 size plane and see how fast I can make it. I got a MVVS 15 with a pipe, I know its not the hottest engine but it should do for now.
I played a little in SW and this is what I got so far
Please let me know what you think, any positive and negative comments are appreciated.

Default RE: Speed plane

Looks like a Hotliner. I'd say you don't need that big of a stab, T tails are usually heavier, give yourself some fuse. Figure out what percentage the fuse is of the frontal area, you'll be shocked how small it is.

With a .15 and a pipe you probably want it to look more like a FAI racer than a hotliner. Do a search of European speed planes to get a starting point.
