Hi my name is Chris, I'm in 8th grade at my school and I'm asking for oppinions on a good science fair project. Last year I did one on how the pitch of a propeller affects the thrust on an airplane. I got 1st place. This year I would like to something a little more exciting, and at the same time, doesn't require lots of money.
Heres one of my Ideas:
How does the CG affect how a plane flys.
Please help,
Chris K
