Once your in PFA mode you have no control until the sequence is finished. I think there is four parts to the sequence cycle to each one using the DIR button. In the last sequence the engine will ring the bell and move out at the speed it came in on, when the bell stops ringing you have control. On my pike the PFA button is off limits unless you are competent with its operation.
As far as taking off to fast , did you set your acceleration speed ?
Hope this helps
