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

how about how airfoils create lift? like how some have an under camber, or a semi symetrical, fully symetrical, or flat bottom

i had a friend do that last year in our science fair and he placed first also

Good Luck,
Scott

i've got an idea. check out this thread. i was in 8th grade when i started this project, and i am sure with my help and the help of some of the other active members on the thread that you would be able to get this together in no time. check this out. that is, if you have a computer radio and a bit of $$ to spare...
