I have bought most of Captain Sim's products for FSX. I'm a little curious about this one though. In effect we paid to beta test the product ( I bought it). However the things that we can point out are things that should have been noticed in the first place. Like switches that function backwards and mispelled graphics. The "meat" of any of these simulators/software are the flight dynamics and how the systems function. My hope is that Captain Sim is not really looking for that type of feedback. That should come from some research into the actual 737 and including some former pilots or boeing engineers. I happen to like the "steam" 60's and 70's aircraft. Hoping someone will do DC-8
