I do all my training part 61 and I was satisfied with the Gleim Private Pilot course kit and while I am considering their instrument course kit I figured I would ask to see if someone has a recommendation for a kit they have used? Maybe a mini-review of sorts?
I have never used Gliem or Sportys, but I do have the King instrument. If you can stand to listen to the dry King humor, they are very informative. Then again I didnt pay for them, so I am biased when they are free!! But I do lend them to my instrument students and suggest they watch them.
