I also have a concept, It's hard to find parts, I've been on line for weeks looking for alternatives for Tower Hobbies, I found a nice set of Composite blades, and I'm thinking about going up to 8 cell pack so I can get a Brushless motor,

I'm trying to think up a good way to mount the battery also,
heres a pic of my setup
