@garyhNot having the horsepower to effectively run the PT19 is one thing. And I think that can be addressed. However, not spending any real time figuring out how the various levers, switches and dials work is quite another. This model is not one you jump into and go fly somewhere. The entire preflight thing is a work of art. Enjoy it or don't but please do not rant about your inability to do so. If you would just take a breath and learn the model you would be much happier. And if I understand correctly, you are simply lacking in RAM. Not a big issue these days. Purchase more. It's cheap. Relatively speaking. Post a log.txt file. Perhaps there is something more going on.
