Here is the program I am running: clearscreen. lock steering to heading 0 by 90. lock throttle to 1. stage. wait 5. lock steering to heading 0 by 30. lock throttle to 0.8. wait until stage:liquidfuel < 300. stage. wait until stage:liquidfuel < 1. stage. lock throttle to 0. until alt:radar > 0 { wait 1. print "Radar Altitude:" + alt:radar. }. until alt:radar < 5000 { wait 1. }. lock steering to velocity:surface + V(1,0,0). until verticalspeed < 10 { print "Radar Altitude:" + alt:radar. lock throttle to 1. }. set VSC to 0. lock throttle to VSC. Until alt:radar < 5 { if verticalspeed > 4 { set VSC to VSC + 0.02. }. if verticalspeed < 2 { set VSC to VSC - 0.02. }. }.
