easy, to get 6k feet just get ful upgrade, then go down slop and stay at same angle. then boost to 200 wen speed drops to 125, then carry on and wait until it drops to 125 again, then boost back to 200. wen it drops to 125 again spend the rest of ur boost on it and make sure ur at 0% but just at 0, press up and down until its just between 1 and 0. then u should od it without a breeze. wen u hit near the end and ur about to hit the water pull up a bit so u dont. thats only if u havent finished and r bout 2 hit teh water
