I find both of those planes you listed pretty easy to hover/torque roll. Can you hover them? Is it just that the plane is not rotating? Anyway... Check your CG. I like to have mine towards the rear. Make sure you have 45* of throw on all surfaces. The plane will rotate in a torque roll quicker if you have a longer less pitch prop than it does with a shorter higher pitch prop. (12x6 rotates the plane slower than a 14X4) And most important of all....practice,practice, practice.
Hope this helps, now go practice
