A very Slight pull toward canopy or belly is quite normal. You can probably trim out most of that tendency.
Drifting up towards vertical is the pilot however!
Trimming fir good knife edge may require some c of g changes. There are some good guides in setting up models for this kind of aerobatic stuff. Triangulation trimming is the name I remember - try Google.

Most of my models have required a small elevator to rudder mix for relaxed knife edge.

As above, but also be aware it is quite possible to apply too much ruder - try using as little as you can get away with to just hold level flight.
IF you still find it is pulling into a turn then you will need to compensate with elevator, and you might need some opposite aileron as well if its trying to roll with the rudder.
When you have worked out what the model is doing then you might be able to mix this compensation in - I have a scaled down Challenger which needs 10% up elevator slaved to left rudder, and 5% up elevator slaved to right rudder to stop it pulling towards the U/C for instance, but I would strongly advise you figure out what is going on before you reach for the mixes - its very easy to over - complicate things otherwise.
