Mr3putt, you cannot do both exactly the same. A true flat spin requires the plane to be stalled, the plane cannot be in a true spin and climb. If you will notice that anytime a person gets one to climb it is always more of a tight flying circle and the wings are tilted some. If you are having problems getting your sledge to do both, it goes to one of two things
1 set up is incorrect
2 your thumbs
Do not take that as criticism, it took me a while to figure it out on the sledge but it has its spot and you will find it with persistence. I have found that most guys have too much aileron in the sledge and therefore they go into a spin and it just blows out of it because they want to shove the sticks to the stops. THe sledge must be finessed to find that right stick position and you will see it does both nicely. Best of luck, do not stop trying. If you are ever at a probro I will show you on mine.
