They removed the limitation, and you can put launches up and down hill.
I tried using LSM's (on torque coaster) as a lift hill (30-35 degrees) for the train like Maverick does (in the video above).
In the game's current state, once the train reaches its target speed, it starts to slow down and fall backwards. The LSM's in the game right now only have launching capability instead of keeping the train at its target speed when going uphill.
Maverick is at my home park and in real life, the LSM's aren't "launching" the train up the hill, they are carrying the train up the hill at a steady speed. The only launch on this coaster is in the tunnel underneath the station. I hope the devs see this feedback.
Oh and to rdrunr7 and AngryGumball: "Blitz" is Intamin's model name for Maverick
