RE: Landing Warbirds
You said you crashed on landing, but that's all we know. There are a lot of reasons for a crash and we don't have that info, so I can't help you with WHY you crashed or how to avoid it.
However, an instructor could.
Get on a buddy box with a qualified instructor, (or at least an expert pilot who can take the plane from you if you get in trouble) and you'll learn to land in no time
