In my review of the electric series I wrote "These are not eye candy for model helicopters, I also wouldn't suggest watching them before driving long distances or operating heavy machinery"

They are scripted but there's lots of corrections with sub titles. He's not the least bit entertaining, but the information is good and presented well.

To answer your question, based on my estimation of your knowlege level from our conversations you would honestly be bored and feel that you wasted your money. Will you pickup a nugget or two? Yes, sure. I appreciated the way he did a few things differently than me but I can't say I "learned" much by watching them and they drag on like the English Patient (a movie that was probably longer than the actual war).

The E series is another matter, I've learned quite a few things watching 7, 8, and 9 but its an area I havent devoted a whole lot of time on. Infact I'll be applying some of the things I picked up from the e series during the upcoming Trex SA and Mini Titan reviews.
