Hi guys,

I dont know anything about the theory..... But I can make a guess, a 3D comes with big control surfaces(and with big throws) , big ailerons,big rudder and big elevator.

From what I have seen up to now you need very very big elevator/s for a 3D plane. I think they are to control a (slow) plane with an aft CG. Other wise a nose heavy plane will not benefit too much from a big elevator. Or with a very fast plane, you get flutter at speeds more likely. So what is the difference between a plane with normal elevator and a plane with big elevator/s. Is elevator stab helping the plane to float ( as a surface like wings do ).

Could anyone tell us about those stuff with a language that we can all understand.

Happy new years.

Regards.

Zafer
