Vindicator experience and the failed Brewster Buccaneer

If France entered a war in 1942, how quickly would it recognize the weaknesses of the Vought Vindicator and Brewster Buccaneer?

The Vindicator could perform its dive-bombing task, while the Buccaneer had serious defects and attracted little operational use; no precise French recognition date is offered.

The Vindicator could carry a bomb, dive on a target with reasonable accuracy, and return. Falling short of the later SBD Dauntless did not make it incapable of its intended task. The Brewster Buccaneer was a much weaker proposition, plagued by problems and judged unsuitable even for RAF training. There is disagreement about how revealing that RAF rejection was, because the aircraft arrived after the Battle of Britain, when British requirements were clearer. The US services' lack of enthusiasm reinforces the criticism of the Buccaneer. No precise timetable is given for a hypothetical French discovery of these problems.
