Not every plane had dive brakes. The dive bombers, of course, did. Some (all?) marks of the P38 had them. The Hog's dive brakes were the wheel covers. You can deploy the Corsair's gear up to about 300 mph to slow down, and, as was mentioned, cross-controlling will slow you down alot. I'm hoping prop drag is introduced soon, as this will help a great deal, also.
