In the case of my plane based on your definition I would say Hover yes, Unlimited vertical definitely not. I can get it to hang there but can't pull out vertically. Like others have already said, if easy torque rolls and unlimited vertical is what you are looking for then go with another plane. If you are still learning to fly you are lacking the flight time and experience to be trying these types of maneuvers - but the LT-40 is a great place to start.
My suggestion... put a Webra .50 or Irvine .53 on the LT-40 and fly it until you know it better than the back of your hand and have the ability to try and hang it on the prop without getting into trouble. Then go out and buy a Hangar 9 Twist or a U-Can-Do .46 and transfer the engine from the trainer to the new plane. You will be able to hang on the prop and have unlimited vertical.

I've had two seperate occasions where my experience with a particular engine did not match up with what others were saying. The first was with an ultra stick where some guy said it had unlimited verticle with a TT46 pro. The second was with a pacific aeromodelers edge 540. This guy said he could maintain a hover with a .46 fx. (6lb plane)
Just so I am clear, I want to explain what my definitions are of the the words hover and unlimited verticle.
If I am wrong in my understanding of these words, please correct me.
1. Unlimited verticle - Person holds the plane by the tail and the plane will climb from a dead stop. (Not a buzz the runway at 80mph and pull up and watch it go)
2. Hover - The plane is oriented in a verticle position (not sorta verticle like a harrier) and the engine will maintain it's altitude.
