try a low wing sport plane like a Sig Somthing Extra . its a tail dragger mid wing will do all the stunts you can think of.
take your time setting the P-40 up read the manual a few times just to get the basics of the plane down. also check the Warbirds section there is a huge section on the H-9 P-40 lots to read you will be surprised this plane is more of a sport plane in warbirds clothing just take your time you will be ready before you know it.
