Hi ive been reading through martin simons basic of model aerodynamics and so far its been really helpful but i still go a couple things that a dont understand:
1) It says the lift is equal to weight and drag is equal to thrust. I understand the second part but about the first part i dont get. If a plane is going 250mph its giving more lift than 50mph right but the weight will still remain the same? So why is the weight always equal to the lift.
2) I haven't read this in the book but theoratically on a wing (and only the wing) is lift = drag. Cause if i increase camber, AOA, thickness,speed, air density they all increase both lift and drag? (this true)
3) Vescocity is drag, right?
4) For some reason i still cant get the P factor if a prop turns clockwise from the cockpit view shouldn't the P factor shift the plane right not left?

Thats all the dumb questions i can think of now probably haev some more later.

Thanks alot,

Papa
