So my question for you is are they drawing that power the whole time? Wont that make them get hot?

Ok. I'm still working on the power issue and I have an idea for a solution but would like some feedback. What is everyone's opinion of having a rechargeable li-po battery pack inside the helmet? I know that there may be some people that do not like the idea, so I'm looking to hear what the general consensus is about it.
Got the email, it may be a possibility but after getting some info on one of the parts, it turns out the 12v may be too much. I do have a solution for that problem, but I want to try a few ideas that I have first.
Andy, I will let you know if I need anything.

i am all for rechargeable btw 
Just about ready to get the boards made. I ran the kit using a NIMH 6v rechargeable battery pack with a modified version of the code to continually rotate the servo every 30 seconds and it ran for over 5 hours with only less than a volt loss on the battery. I am going to try it with regular alkalines as well as lithium and nicad rechargeables to see which is the most cost effective and runs the longest. I am hoping to get a similar battery like out of standard alkalines, that way I don't have to add a power switch (there is one on the battery holder) as well as not having to worry about providing a rechargeable pack and charger.

I ran the kit last night with 4 regular alkalines AAs and it ran for over 5 hours non stop before I shut it down. They were batteries that I had used before, so brand new ones should theoretically run for 6 or 7 hours, but don't quote me on that. I was going to try 4 non-rechargeable lithium AAs, but I forgot them at home. I will try those tomorrow, but given that the standard alkalines lasted over 5, the lithiums should do more than that easily.
So it looks like the entire kit should run off of 4AA batteries (i don't know if 4 rechargeable AAs like NICAD and NIMH will work since their normal voltage is 1.2v not the 1.5v that alkalines and lithiums have). I also shrunk down the size of the PC board down to 2 inches square, so it shouldn't take up too much room inside the helmet. Right now I don't think I will provide an enclosure for the board, but I may later on if I find one that I like.
Once I get the boards made and am ready to start the run, I will post here. I will be using sellbuddy for these kits just like my other ones. I haven't decided on a final price point yet, but it will be less than $200, and it will include the servo, servo extension, controller board, battery holder with switch, wireless transmitter, as well as accurate alco mpa106f gauntlet switches. These switches are momentary ones, not push on/off ones like used in the film, but they look exactly the same.
