This is a very comprehensive set of lesson plans that is well worth the money. I highly encourage cfi applicants to purchase their lesson plans. If you decide to build them yourself, that’s great, and you’ll be better off for it (having researched all the material and referencing it with official FAA publications for literally weeks on end) however for those that just want to get their CFI certificate done, this is for you. Time is money and let’s face it, you’re not supposed to reinvent the wheel here. These lesson plans are so well written that if you really wanted to you could teach straight out of. I gave “the whole shebang” 3 stars because 1. There are a lot of typos here and there, and I’ve seen one huge error (in their airspace VFR night wx requirement for class G airspace) and another because they tailored their lessons for a diamond plane. You have to go through literally all the lesson plans and make sure that the flow, organization and correct aircraft are used. So basically it is a great starting point, besides a couple of errors here and there, they’re a pretty solid lesson plan. Mad props to the organizers of these lesson plans.
