With the rates turned down - it's a friendly kind of a plane

With the rates turned up - it's still a friendly kind of a plane - it's just that the friend has now gone wild

As long as you've learnt the basic aerobatic skills (Inverted flight, loops rolls etc) and the recovery from them - I say go for it they are a great plane to fly. Like any of these style of planes - there are no "Self righting" qualities - it's what makes them good 3D'ers - they go exactly where you tell them even if it's not what you really meant. As a trainer - they are tough as nails so when you do make that mistake, they often survive unscathed.
