Mosquito 6pdr not dealing damage

I've been getting the same problem with the spitfires rockets. They detonate before getting anywhere near the enemy plane, causing no damage. Its like enemy planes have a force field, the only ways I can do damage with rockets to planes is if I'm touching  the enemy so the explosion does damage to both of us. To quote the 5.2 update notes "This also makes them more viable air to air weapons"... this update is a joke!
