We flew our redesigned gliders using our rubber band
launch system.
All students used an elliptical design for the wings. We used basswood
bodies to help with the breakage problem. Everyone improved flight distance.

Recent Results:
Here are the flight records from the second batch of gliders (wing modification).
We went with basswood for the bodies because the balsa wood was so fragile.

Flight Procedure:
All flights were indoors.
There was limited space to fly, so gliders that flew straight had an advantage.
We had no wind indoors.
Each glider was tossed 3 times. The longest flight was recorded.
Modifications:
Most flyers put clay on the nose of their gliders.
All flyers had 1-piece wings this time.
About half the flyers rounded the tips of their wings.
Some flyers also rounded the tips of the stabilizer.
One group made a trapezoid-shaped wing.
One group tried making their body flat.
Two groups shaped their wing in a semi-circle.
James's Glider had clay on the nose. The body was
broken just before it was to fly so a fast repair was made with scotch
tape. The wings were rounded in the front and square in the back. The
stabilizer was tilted slightly down to the left.
Conclusions:
The amount of force used to launch the glider depended on the weight.
These planes were smoother.
They were balanced better right-to-left and front-to-back.
Our Earlier Results:
We flew our gliders last week. Here are the results: Each glider was tossed
three times and we took the farthest distance- We flew the gliders indoors
so the wind would not influence the test. Quinton's Team - Weight 4 grams

Some planes broke when they hit the ground.
Suggestions for the next plane:
Try to make the wings even on the body.
Try to even the weight over the entire glider.
Make the wings rounder.
Put more weight on the front of the glider.
Try to duplicate the back of the glider.
Try to make the weight even between the front and the back.
Try to make the plane heavier.
