yeah i made it to 6000 feet heres how to Get eveything. Then get your resistance to exactly 3% or at least pretty close. Then use your rocket to get up to 200 mph. Once the speed goes down to 175 mph, boost it back up to 200. Keep doing that until you are out of fuel. Then when you are out or rocket fuel, go down then up. Don't let your resistance go up to more than 6%. When you go back up you should have your resistance back at 3%. If you have done this correctly, you should have gotten far. This does work. I know coz i did it just then wewt!
