Both of these mods (PWM & DNA75 Squonker) were built with basic hand tools.It's an idea @bombastinator. At least if you put something together and sensibly, it can always be repaired or upgraded.
First thing to look at is lipo or li ion, and then chipset and work around the components. Maybe even get a few small pieces fabricated by local Engineering and or sheet metal companies.
Seriously considering this myself, but it's just some thing need the proper equipment to be done. Can only do so much with an electric hand drill, a hacksaw, a file and sandpaper.
Please ignore the liberal use of hot glue, I ran out of epoxy at the time and actually detest using hot glue. It's hidden on the inside, nobody sees that anyway.
