no doubt players of GTA Vice City finds demolition man mission difficult to play, most players prefer to skip the mission, mostly because of the fact that the RC helicopter is not an easy control. However, with the right settings your helicopter moves easily. I actually found out that I enjoy playing demolition man mission easily.
so just follow the following setup;

open GTA Vice City
go to settings
standard controls
redefine controls
change forward button to: the shift button or any button of your choice
scroll down to look left + turrent L: press the left button
look right + turrent R: press the right button
turrent + lean up: press the Up button
turrent + lean down: press the Down button

making this settings will disrupt the default settings which will change the previous keys to Unbound so be sure to change those Unbound keys to other keys other than the keys used for the turrent settings. Go back to control your RC Helicopter easily.

Remember the trick is to go to the area first and kill the workers and securities there before activating the timer. if you cannot keep up with the timer, it is advisable to activate the cheat 'booooooring' to slow the timer, to increase the speed of the helicopter while on 'booooooring' cheat you should fly your helicopter above ground level. enjoy your demolition man mission, and don't forget to share how this settings benefits you.
