UPDATE! 9/29 - My DR - modded to accept standard 6V Rx packs...
 

I have modified it to accept 6V Rx packs instead of $12 worth of Lithium batteries! I am still working out a solution to mount it and get it waterproof and stuff like that though. I also plan to add a Tamiya 1/32 Ford F-350 body to it very soon, so keep up on updates!

here is the link to my webpage where the Steps to do it are explained:

I also have a 4 minute vid of the DR in action with music and audio. You will need the FREE divx codec to view it. You can get the codec from (right click, save as)http://download.divx.com/divx/DivX505Bundle.exe.
