Well, sorry, I have not much to say. I would say that the ramped wings should be better for wheel drag but I'm not sure.
I'm astonished by the lack of support from mods even when new members are asking "pretty please". It's painful to see how the threads about F1 in Schools have degenerated into nothing. I used to believe that moderators were here not only to erase OOT posts and profanities, but to encourage people to become members by enriching discussions, but it seems I was wrong: more members seem happy these days with fewer discussions and, alas, few original threads.
read the links above there is tons of good info in there you will find most of your questions have been answered some with colorful pictures. The point of F1 in schools is not for us to give you the answers but to show you the way to find them them.
