Location of AT-400 (747) 

In Las Venturas Airport there is a very large, lone hanger at one end of the main runway. If you walk up to it it opens top to bottem.

Its difficult getting it out undamaged, but you can reach max height with it, plus you fly so high that flying over area-69 wont get you a wanted level. A must for the skydiver.

Use the Vortex as a Submarine 

Use the Vortex between El Quebrados and the abandoned airfield to take the small unique jump ramp that's on the back of the small shack it's parked next to. When you land in the water, the unique jump slow-motion cinema should keep going, with the camera fixed in one spot. Drive way out into the reservoir, and towards the dam, to the left of the camera's view. You'll disappear from view, but keep going. Eventually you'll run into the side of the dam and the cinema will end, leaving you under water and able to steer the Vortex like a submarine, without draining lung capacity or anything, as if you weren't underwater at all.


Chilliad Challenge easy win alternative way 

Another way to easily complete every race in the Chilliad Challengeis quite simple, throw a grenade at your opponent(s) and they will be eliminated from the race. Normally, using a weapon will get you disqualified, but using a grenade is fine by the games standards, and this method is a lot less cheap than the other one for this challenge, and works just as effectively.
