FAQ "The Power System Corner" -INDEX- w/Lucien Miller on AllThingsThatFly&InsideHeli

[rpmrpm]

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.

Introduction of the PSC by Lucien......

Hello again everyone,

I am sure that many of you listen to the great shows on the All Things That Fly website. There are two different segments each week, Inside Heli and ATTF. Inside Heli, as the name would imply, is dedicated to discussion of helicopters and helicopter products. The ATTF show is primarily focused on fixed wing aircraft, and hobby related topics in general. Their website can be found at www.insideheli.com .

Starting tonight, Innov8tive Designs will be sponsoring a new segment on the show called "The Power System Corner". This will be a short section of the show, around 5 minutes or so in length, that will be dedicated to answering questions about Electric Power Systems in aircraft and helicopters. This new segment will be a part of every show from now on, and I will be fielding questions that are submitted on the show site by viewers. I will be answering the Helicopter related questions on the Inside Heli show, and General Power System questions and those dealing with airplanes on the ATTF show.

Tonight we will be recording the first segment for the ATTF show, which should be Episode #70. Innov8tive Designs will be providing prizes to the submitter of each question used on the air, and we will also be providing some nice Motor and ESC combos for the monthly raffle prize on the show. If you have a question that you would like to have answered live on the air, then please submit them to the guys over at All Things That Fly.

For those of you that are regular listeners of the show, you may have heard the interview that I did back in June this year, where we discussed my trip to the Scorpion Factory. If you missed this show, you can find it at Inside Heli Episode #24. I put together a 5-page website with all of the photos that go along with the show as we discuss the various topics during the interview. A link to this page is provide in the show notes, just below the show description.

Both the Inside Heli and the ATTF shows are great to listen to, and every episode has a bunch of good information, so be sure to stop by and check it out. Each of the shows can be listened to on the web, and for those of you with MP3 players, each show is available as a PodCast. You can subscribe to the show and download all the new episodes to your I-pod and take them with you to listen while you work, or why you drive in the car.

I am really excited about our involvement with the show, and hope that you all can listen in and get some good information!

See you all later!

Lucien

Reserved, To be used if additional details need to be added at a later date.

[apriliamille]

sweet.
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

[bullseye000]

Someone made a nice compilation episode of all the PSC segments and they posted it on the ATTF site before SEFF. I've listened to it a couple of times while waiting to pick up my kids.

[rpmrpm]

Yes but I do not believe it has all the content in it, Does it?

[Diggs]

Ah yeah. I am there when Lucien does the PSC and I am happy to see this. He has great info and has helped me a ton! Thanks for hooking us up with the index!

Diggs

[cmulder]

i you have time make the data into links so people can dl the potcast straight away

[rpmrpm]

Good idea, I will look into that.

[rpmrpm]

Thanks Diggs, I added that link to the index header.

[rpmrpm]

I am shocked how much material the show/shows have covered in just over 2 years. The PSC's are just a small portion of the total content. I find myself searching for the PSC's and stopping to listen through the hole show instead. Awesome job guys, Thanks

[GFBurke]

Thanks for this! I'm sorry you have to listen to us so much... He is sacrificing for YOU guys!

If I here Burkes voice in my head as I fall asleep tonight, I QUIT............
