"The Power System Corner" -INDEX- w/Lucien Miller on AllThingsThatFly&InsideHeli
AllThingsThatFly and InsideHeli podcast are great podcasts, The originals in my opinion.
I find it...
1. Very entertaining. Like setting at the field w/the guys and just BSing about RC.
2. Very informative. Great to hear others comments on products and experiences.
3. A resource. If you know nothing about RC flying and just listened to every episode you could gain A pretty good knowledge of RC flight.
One of these resources is "The Power System Corner" sponsored & hosted by Lucien Miller of http://www.innov8tivedesigns.com/ the US dist. for SCORPION Products.
I have found myself wanting to go back and listen to specific questions & answers but have had a hard time finding them. SO..... This will be the -INDEX-
This is in no way an attempt to cut out the hard work that the Host's(Jamie, Chris, Diggs & James) put into each episode. You would be missing alot if you skipped the full episodes and jumped around.
THE -INDEX- I am going back and listening to all episodes and pulling out the episode # and the time stamp of the questions and will form this index as a resource for myself and others, If you don't want it, don't look. All comments and suggestions will be accepted. IE; If you have better/different verbage to describe the question being addressed, that would help other understand what is being asked, please post and I'll ad/change the list. This will be a work in progress, and will be updated/added to.

couple times i have wanted to go back and re listen to stuff that is way beyond my primitive mind's ability to understand. or i simply forgot. this will help a bunch
i pulled up 79 the other day for someone to listen about dual motors on a single esc. its at the 24:40 mark there are some others in that episode i.i.r.c. just remember that one specficially from the other day
