Ok I might be harsh here but follow along. If you know the drill and it's not rocket science how come with all your hours you didn't make it through RAH on a much easier plane to fly? Everybody learns at different paces as we all know but you're trying to imply that because you have 1700 hours (not many at all) grew up in aviation got your Private early on and flew in the NE not sunny FL you're somehow better than 400hr guys? Mind you many 400hr guys made it through RAH's and other more difficult programs but with all your experience you didn't....

What Chrisw said is valid, but mind you he also went through the 1900 program before Saab, he had a good hand flying foundation down pat before hand and was also indoctrinated in the 121 flying environment before going through transition as did I which helped immensely in the switch to the Saab. You say you are used to flying equipment like the Saab I'm assuming you are correlating the fact that you flew non/partial glass 6 packs and turbo props which is great and a lot more similar than the 170 you started training on but the glass is there to help not hinder so just because this is similar to what you have it's not going to be anymore easier.

I think it's more an attitude problem in keeping you back from excelling rather than an actual deficiency in skills many of us have been there done that in regards to that department as have I fix that first and you'll have a chance at passing training.
