Default SHORTY ? ? ? ? My newest bird.

For this one, I started with a fully symetrical wing for a pylon racer and this is what I ended up with.

Fully symetrical 72in triple tapered wing, 10in at the root, 5in at the tip, 2 in ailerons tapered to 1in, 19in fuse, soda bottle canopy, .32sx, 6oz tank, AUW 3.3lbs.
This started off as a pylon wing, but I thought it might not be strong enough. Sooooo, I built a sm fuse for it. Very fast, decent roll rate, whips around the turns! Slow stall speed, but too much up elevon and it will tip stall. A very fun plane to fly.

Hey,

What are the dimensions of the spar? 72 x ??? Did you use a standard yard stick, or two of them spliced together.

Where's your CG?



Looks cool, very cool.

I used a total of 4 yardsticks (2 butted end to end and a doubler on both sides). I tapered the spar
from full height down to 1/2 of that at the tips. I used the CG calc to determine 15% of the avg chord,
11 to 18% on flying wings. I have since built another, with smaller simpler wings:

Semi-symetrical 48in wing, 10.75in avg chord, 2.5 in ailerons tapered to 1in, 19in fuse, .32sx, 6oz tank,
AUW 3.0lbs. I have an available Leo .37 I might put on this one.

This is a very similar wing to the one that's on my combat rail, which is a smooth flying, fast,
maneuverable plane. I wanted to fly this one yesterday, but the torenchal(sp) down pour has washed
out the road to the field. Florida is sinking!

LOL ! I could use a small boat. The water level in some of the rivers here are approaching 11ft above normal. I saw an alligator in a cow pasture on Saturday. They're all over the place now, not just in the lakes
