How do you complete mission mad dog D on grand theft auto san Andreas?

To regain control of Madd Dogg's mansion, CJ has to fly in from Las Venturas with some of the triad mob, in the mission A Home In The Hills. They have to parachute on to the roof of the mansion and kill off the Vagos gang protecting the outside, before moving in for a difficult battle with the rest of Big Poppa's men. As CJ only has a handful of triad guys left to help him, he often ends up on his own. If he manages to down all the Vagos gang, the final part of the mission is to chase Big Poppa, who runs outside into his car. CJ has to drive and catch Big Poppa and eliminate him (a hard job!). Once he has done this, the mansion belongs to CJ, and Mad Dogg can start recording inside his studiOS again.
