Gross weight differences O-2 vs. 337

[awilps]

Herb is right. The O-2A/M337B, from my limited experience with it, has a type certificated max gross of 4300lbs. Higher weights were possible for takeoff and landing in military use, but I believe the extra weight had to be in the form of jettisonable wing stores. Landings above a certain high weight number also warranted completion of paper work and a special inspection by the military, post landing.
